What is PharmChek?

PharmChek is a continuous drug-monitoring product built around a sweat patch: a small adhesive patch worn on the skin that collects sweat over several days and is then analyzed for drugs of abuse. According to the site, the patch detects marijuana, cocaine, opiates, amphetamines and methamphetamine, PCP, fentanyl, oxycodone and oxymorphone, hydrocodone and hydromorphone, benzodiazepines, methadone, and buprenorphine. The company presents it as a long-established, economical option for long-term continuous testing, positioned against urine, saliva, and hair testing. PharmChek is now part of SCRAM Systems, which the site describes as the manufacturer and sole source provider.

The practical appeal is wear-and-collect rather than point-in-time sampling. A patch stays on between appointments, so it can capture use across a window instead of only what is detectable in a single urine or saliva sample. That makes it relevant to courts, community supervision agencies, treatment programs, and employers that need monitoring over weeks rather than a one-off screen.

H3 Trade-offs to weigh

  • Continuous coverage: suited to ongoing compliance monitoring, where sporadic testing might miss use.
  • Collection routine: the patch must be applied and removed correctly, so training and certification matter. PharmChek offers virtual training sessions and a 25-question certification exam for applying and removing the patch.
  • Method fit: the site claims advantages over urine, saliva, and hair testing, but the right choice depends on detection window, budget, and what a program is legally required to use.

H3 A concrete scenario A community corrections officer supervising someone on a treatment court docket might use a sweat patch for a two-week monitoring window, then send it for laboratory analysis, rather than relying on random urinalysis alone. Before adopting it, check whether your jurisdiction accepts sweat-patch results and how your lab handles chain of custody.

Next step: request a quote or start certification through PharmChek, and compare the patch against your current method using detection window, collection burden, and cost per monitored day.

How does the PharmChek sweat patch work for continuous drug monitoring?

The PharmChek Sweat Patch is a wearable, bandage-like device worn on the skin for an extended period to collect sweat continuously and test it for drugs of abuse. According to the site, it detects marijuana, cocaine, opiates, amphetamine, methamphetamine, PCP, fentanyl, oxycodone, oxymorphone, hydrocodone, hydromorphone, benzodiazepines, methadone, and buprenorphine. PharmChek presents it as a long-term, continuous monitoring option that it says offers advantages over urine, saliva, or hair testing, and notes it has been in use for over 30 years. The site also highlights training through the PharmChek Academy and a 25-question certification exam covering application and removal.

How it works in practice

A patch is applied to clean skin and worn continuously, collecting sweat over the wear period rather than capturing a single point-in-time sample. When removed, the patch is sent to a laboratory for analysis. This design supports monitoring windows of days to weeks, which can suit programs that need to detect drug use between appointments rather than only at the moment of a visit.

Where it fits

  • Community supervision and court programs: the site's blog discusses choosing testing methods for these settings, where continuous coverage can reduce gaps between scheduled tests.
  • Treatment and recovery monitoring: longer collection windows can give a more complete picture than intermittent urine screens.
  • Workplace or safety-sensitive roles: continuous collection may deter and detect use across a work cycle, though program rules and legal requirements vary.

Trade-offs to weigh

  • Continuous vs. point-in-time: a patch covers the whole wear period, so it can catch use that a single urine sample might miss, but it does not give an instant result at the moment of application.
  • Detection scope: the panel is broad but specific; confirm the analytes you need are included before choosing it.
  • Operational needs: application and removal require trained staff, and results depend on laboratory processing, so plan for turnaround time.
  • Program fit: cost, chain-of-custody rules, and participant acceptance differ by setting; the site's "Request A Quote" and "Pay Your Bill" pages suggest pricing is handled directly rather than published.

Practical next step

If you are selecting a method for a supervision or treatment program, list the drugs you must detect, the monitoring interval you need, and your acceptable turnaround time. Then compare the patch against your current method on those three points. For hands-on readiness, the site's Academy training and certification exam are the starting point for staff who will apply and remove patches.

For related context on monitoring technologies, see SCRAM Systems.

How does PharmChek compare to urine, saliva, or hair testing for detecting drugs of abuse?

PharmChek positions its sweat patch as a continuous-monitoring alternative to three point-in-time methods: urine, saliva, and hair testing. The core difference is the collection window. A patch is worn for an extended period, so it accumulates exposure across days rather than capturing a single moment. Urine and saliva are snapshots; hair gives a long retrospective window but cannot show recent use in the last several days.

Practical comparison

Method Typical detection window Main strength Main trade-off
PharmChek sweat patch Continuous wear over an extended period Detects use across the whole wear period, not just one moment Requires correct application, adhesion, and removal; results depend on proper wear
Urine Hours to a few days Familiar, widely accepted, low cost per test Easy to dilute or substitute; misses use outside the window
Saliva Roughly a day or less Quick, observed collection, hard to adulterate Very short window
Hair Weeks to months Long retrospective history Cannot detect very recent use; slower turnaround

PharmChek states it detects marijuana, cocaine, opiates, amphetamine, methamphetamine, PCP, fentanyl, oxycodone, oxymorphone, hydrocodone, hydromorphone, benzodiazepines, methadone, and buprenorphine, and describes itself as a long-standing, economical option with advantages over the other three methods. It is now offered through SCRAM Systems, which also runs training and a certification exam for applying and removing the patch.

How to choose

If your program needs to know whether someone used at any point during a supervision period, continuous sweat monitoring fits better than a single urine or saliva sample. If you need a long history at intake, hair testing answers a different question. If you need a fast, low-cost checkpoint, urine or saliva may be sufficient.

A concrete scenario: a community supervision officer who tests a client only on scheduled visit days will miss use between visits. A patch worn continuously closes that gap, but it also shifts the burden onto correct application and wear compliance — a loose or removed patch undermines the result. That is why the certification and training components matter as much as the device itself.

Next step: request a quote and confirm which panel and wear period match your program's requirements, then compare the per-client cost against your current urine or saliva schedule. For background on how courts weigh these methods, see the site's blog article on drug testing in court.

What drugs can PharmChek detect?

PharmChek’s sweat patch is described as detecting marijuana, cocaine, opiates, amphetamine, methamphetamine, PCP, fentanyl, oxycodone, oxymorphone, hydrocodone, hydromorphone, benzodiazepines, methadone, and buprenorphine.

That list covers several common drug classes:

  • Stimulants: cocaine, amphetamine, methamphetamine
  • Opioids: opiates, fentanyl, oxycodone, oxymorphone, hydrocodone, hydromorphone, methadone, buprenorphine
  • Depressants: benzodiazepines
  • Dissociative anesthetic: PCP
  • Cannabinoid: marijuana

For a practical next step, confirm the exact panel and cutoff levels with the testing program before relying on the patch for a specific substance. A supervision agency, court program, or treatment provider may need to verify that the drug it cares about is included in the ordered panel and that the result will meet its legal or administrative requirements. PharmChek’s own site presents it as a continuous monitoring option and notes that it has been used for long-term drug testing for over 30 years.

How can I get certified to apply and remove the PharmChek Sweat Patch?

PharmChek offers a dedicated online certification path through its PharmChek Academy. According to the site, this involves comprehensive virtual training followed by a 25-question exam; passing certifies that you can apply and remove the PharmChek Sweat Patch.

Practical route

  1. Go to the PharmChek Academy section on PharmChek and sign up for the training session.
  2. Complete the virtual training at your own pace or as scheduled.
  3. Take the 25-question certification exam.
  4. Once certified, you can apply and remove the patch in your own setting.

Who this is for This is aimed at professionals who need to conduct continuous drug monitoring—typically those in community supervision, court programs, treatment centers, or workplace testing. If your role involves collecting samples or managing a testing program, this certification lets you handle the patch directly rather than sending it out.

What to expect from the exam The site describes it as a 25-question exam, so it is not a lengthy credential. The training is virtual, which means you can complete it without traveling. The emphasis is on correct application and removal technique, which matters because improper placement or removal can affect sample integrity.

Trade-off to consider The certification is product-specific. It qualifies you to use the PharmChek Sweat Patch, not drug testing methods in general. If your program uses multiple testing methods—urine, saliva, hair, or sweat—you will likely need separate training or procedures for each. That said, the patch itself is designed for long-term continuous monitoring, which is a different use case from point-in-time tests.

Next step Visit the PharmChek Academy on the official site and sign up. Before you start, confirm with your organization whether they require this certification for your role and whether they have any additional internal training. If you are comparing methods for a court or supervision program, the site's blog post on choosing the right testing method may help you decide whether the sweat patch fits your needs.

How do I pay my bill or request a quote for PharmChek?

You can pay an existing PharmChek bill online through the company's payment page, and you can request a quote for products or services by using the "Request A Quote" option on the site. Both actions are aimed at organizations and individuals already working with PharmChek's drug-testing products, such as community supervision agencies, treatment programs, and courts.

  • Pay a bill: Use the "Pay Your Bill" page linked from the site: PharmChek Pay Your Bill.
  • Request a quote: Look for the "Request A Quote" button on the PharmChek homepage. It is the main path for pricing inquiries, since the site does not publish product prices directly.

If you are evaluating PharmChek for a program, the quote request is the more useful first step: it lets you describe your testing volume, the substances you need to monitor (the patch covers marijuana, cocaine, opiates, amphetamines, methamphetamine, PCP, fentanyl, oxycodone, oxymorphone, hydrocodone, hydromorphone, benzodiazepines, methadone, and buprenorphine), and whether you need training or certification for staff who apply and remove patches. PharmChek also offers an online certification exam and virtual training through its academy, which may be relevant if you are comparing vendors on onboarding support rather than price alone.

A practical next step: before requesting a quote, write down your expected number of participants per month, the drugs you must detect, and your preferred testing interval. That information will make the quote conversation faster and give you a clearer basis for comparing PharmChek with other monitoring options. For general context on how agencies choose among testing methods, the PharmChek blog post "Drug Testing in Court" discusses strengths and limits of common approaches.

What Is NASA GMAO? Global Modeling and Assimilation Data Explained

NASA's Global Modeling and Assimilation Office (GMAO) is the part of NASA's Earth science effort that builds global models of the Earth system and combines them with satellite and other observations through data assimilation. If you need research-grade atmospheric, land surface, ocean, or ozone fields — especially for subseasonal-to-decadal timescales — GMAO is a primary source. If you need a consumer weather forecast or a simple point-and-click local outlook, GMAO is not that; it produces the underlying model and reanalysis data that other services build on.

What GMAO actually does

GMAO's work sits at the intersection of two activities:

  • Global modeling — running numerical models that simulate the atmosphere, land surface, ocean, and chemistry on a global grid over time.
  • Data assimilation — merging those model simulations with real observations (largely satellite) to produce a physically consistent, gridded estimate of the Earth system state.

The assimilation step is what separates a reanalysis or analysis product from a pure forecast: observations constrain the model so the output stays anchored to what actually happened, while the model fills gaps where observations are sparse.

The main product areas

GMAO's stated scope covers several Earth system components. The table below maps each to what it typically means for a user.

Domain What it covers Typical use
Atmospheric Winds, temperature, humidity, pressure fields Weather and climate diagnostics, model evaluation
Land surface Soil moisture, surface fluxes, land-atmosphere exchange Drought, hydrology, agriculture research
Ocean Sea surface and ocean state variables Coupled climate and seasonal prediction work
Ozone Atmospheric ozone fields Atmospheric chemistry and stratospheric studies
Subseasonal to decadal Forecasts and analyses on weeks-to-years timescales Seasonal outlooks, predictability research

If your question is "what did the atmosphere look like over a region last month" or "what does the model project for the coming season," these categories tell you which product family to look in.

How to access GMAO data and documentation

GMAO publishes its research, model descriptions, and data products through its site at gmao.gsfc.nasa.gov. A practical path:

  1. Start with the research/product pages to identify which model or dataset matches your variable and time range.
  2. Read the documentation for that product — resolution, time span, and known biases determine whether it fits your use case.
  3. Download or query the data through the access method the product page specifies.
  4. Validate against your own observations before relying on it, since reanalysis and model fields carry resolution and bias limitations.

The site is documentation- and research-oriented, so expect to read product descriptions rather than find a single unified download button for everything.

When GMAO fits your work — and when it doesn't

Good fit:

  • You need gridded global fields for research, model evaluation, or downstream processing.
  • You work on subseasonal-to-decadal timescales or Earth system components like land, ocean, or ozone.
  • You can handle scientific data formats and read documentation.

Poor fit:

  • You want a ready-made local forecast for planning your day — use a consumer weather service instead.
  • You need a guaranteed, plug-and-play API with no setup.
  • You need commercial support or a service-level guarantee; GMAO is a NASA research operation.

Common limitations to plan for

  • Resolution and bias. Global model and reanalysis fields are gridded estimates, not point measurements. Local accuracy varies.
  • Documentation-dependent use. Correct interpretation requires reading the product notes; using a field without checking its time span or version can lead to wrong conclusions.
  • Research orientation. Access methods and formats assume a technical user.

If your task is research or development that needs global, physically consistent Earth system data, GMAO is worth checking first. If your task is a quick local forecast, look elsewhere.

What Is a Family Crest and How Do You Find Yours?

A family crest is not the same thing as a coat of arms, and that distinction matters if you want to research or use one correctly. Strictly speaking, the crest is only the emblem that sits on top of the helmet in a full heraldic achievement. The shield, helmet, crest, and mantling together make up the coat of arms. Many people casually say "family crest" when they mean the whole design, but in heraldry the words are not interchangeable. A crest belongs to a specific person and is passed down by inheritance, not shared by everyone who happens to have the same surname.

Crest vs. coat of arms: the parts and the terms

A complete coat of arms, often called an "achievement," can include several components:

  • Shield (escutcheon): the central surface carrying the main design.
  • Helmet: sits above the shield and indicates rank or status in some traditions.
  • Crest: the figure mounted on top of the helmet, often an animal or object.
  • Mantling: the cloth-like drapery flowing from the helmet.
  • Motto: a phrase on a scroll, sometimes but not always present.

So when a product advertises "your family crest" as a shield with your surname under it, it is usually using the term loosely. The shield design is the coat of arms; the crest is the smaller piece above it. Knowing this helps you ask better questions when you research or buy anything heraldic.

How heraldry is inherited

Heraldry developed in medieval Europe as a way to identify individuals in battle and on seals. Because it identified a person, it was granted to that person and then passed down according to rules that varied by country and tradition. In many systems:

  • Arms descend to descendants of the original grantee, often through a specific line.
  • Different countries and heraldic authorities apply different rules for cadency (distinguishing branches of a family).
  • A surname alone does not entitle anyone to arms. Two unrelated families can share a surname, and only one may have a recorded grant.

This is the single most important point for research: sharing a last name with someone who had a coat of arms does not mean those arms are yours. A reputable heraldic source will say this plainly. A novelty seller usually will not.

Steps to research your family's heraldic history

Research works best when you move from your own family outward, documenting each generation before jumping to a famous name.

  1. Start with what you know. Collect names, dates, places, and documents from living relatives and family records.
  2. Build a documented pedigree. Use civil registration, census, parish, immigration, and military records to trace each generation back.
  3. Identify the country and region of origin. Heraldic records are organized by nation and often by region, so this narrows your search.
  4. Check the relevant heraldic authority or register. Many countries keep official records of grants and confirmations.
  5. Look for a proven connection to a grantee. Only when you can trace descent from a person who was granted arms can you reasonably claim those arms.
  6. Record your sources. Note where each fact came from so your conclusions can be checked.

If your research does not connect you to a grant, that is a normal and common result, not a failure.

Reputable sources vs. novelty sellers

Signal Reputable source Novelty seller
Language Explains that arms belong to individuals, not surnames Implies every surname has "a crest"
Evidence Cites registers, grants, or documented pedigrees Offers no provenance
Scope Tells you when nothing is found Always has a design ready to sell
Product Research services, transcriptions, reference works Mugs, plaques, and prints with a surname

A useful test: if a seller claims to have "the" crest for your surname without knowing your lineage, treat the design as decorative, not genealogical.

What you can legitimately use if no crest exists

If your research finds no grant connected to your family, you still have options:

  • Use the arms only if you can prove descent from the person they were granted to.
  • Apply for a new grant where a heraldic authority exists and accepts petitions; this creates arms for you personally.
  • Design a personal emblem for non-heraldic use, clearly not presented as an inherited coat of arms.
  • Display arms as decoration if you understand they are not yours by right, though some traditions discourage this.

The honest answer to "how do I find my family crest" is often: first find out whether your family ever had one, and only then decide what you may use.

What Is the PharmChek Sweat Patch and How Does It Detect Drugs of Abuse?

The PharmChek® Sweat Patch is a wearable device for continuous, long-term drug testing. Worn on the skin, it collects sweat over days or weeks and is then analyzed for drugs of abuse. According to PharmChek, the patch has been used for over 30 years as an "economical device for long-term and continuous drug testing," and the company positions it as an alternative to urine, saliva, or hair testing. It is manufactured and supplied by SCRAM Systems, which PharmChek describes as the manufacturer and sole source provider.

How the Patch Works

The patch is applied to the skin and worn continuously. While it is on, it absorbs sweat, which carries traces of substances the body has metabolized and excreted. When the wearer removes the patch (or when it is removed by a monitoring professional), the collected sample is sent for laboratory analysis.

This design produces a cumulative record of the wear period rather than a single point-in-time snapshot. That is the core difference from a urine or saliva test, which reflects a much shorter window.

Application and Removal

PharmChek offers an Online Certification — a 25-question exam — for people who need to apply and remove the patch. The company also runs the PharmChek® Academy, described as "comprehensive, virtual, and engaging training sessions to get the most from PharmChek®." If you are a program administrator or officer setting up testing, certification is the practical starting point.

What the Patch Detects

PharmChek states the patch detects the following substances:

Category Substances listed by PharmChek
Stimulants Cocaine, Amphetamine, Methamphetamine
Opioids Opiates, Fentanyl, Oxycodone, Oxymorphone, Hydrocodone, Hydromorphone, Methadone, Buprenorphine
Depressants Benzodiazepines
Cannabinoids Marijuana
Dissociatives PCP

This is a broad panel covering the major drug classes typically monitored in court and supervision settings.

How It Compares to Urine, Saliva, and Hair Testing

PharmChek claims "distinct advantages over urine, saliva, or hair testing," but the useful comparison is about detection window and collection logistics, not a blanket ranking:

  • Urine and saliva — reflect recent use over a short window; collection happens at a single appointment.
  • Hair — reflects a longer retrospective window, but requires a hair sample and has its own detection characteristics.
  • Sweat patch — provides continuous monitoring across the entire wear period, so it captures use that occurs between appointments rather than only what is present at the moment of collection.

The trade-off: a patch must be worn consistently and remain intact, and results depend on laboratory analysis of the collected sample. PharmChek's own framing is that the patch is "better, cleaner, and smarter" — a marketing claim, so weigh it against your program's requirements rather than treating it as a neutral benchmark.

Typical Use Cases

PharmChek's materials point to community supervision and court programs as core applications. The company's blog discusses "Drug Testing in Court: Choosing the Right Testing Method," exploring "the strengths and limits of common drug testing methods for community supervision and court programs." Treatment and monitoring programs that need continuous rather than episodic testing are the natural fit.

How to Get Started

PharmChek lists several entry points on its site:

  1. Request a quote — for organizations evaluating the patch for a program.
  2. Online certification — complete the 25-question exam to be certified to apply and remove the patch.
  3. PharmChek Academy — virtual training sessions for getting the most out of the product.
  4. Pay your bill — an existing billing portal at pharmchek.com/pay-your-bill.

Pricing is not published on the pages reviewed here; a quote request is the route to cost information.

Website Overview

Identifiable technologies and additional version or configuration signals make the service easier to fingerprint, which may help targeted scanners narrow their checks. An established domain and managed infrastructure suggest continuity of operations and may support dependable delivery, although neither guarantees service quality.

Domain and Registration

Registered in 2013, this domain has about 13 years of history. That suggests continuity, although ownership and purpose may have changed. Transfer-protection status is present, helping reduce the risk of unauthorized domain transfers. The domain uses the common .com extension, which is not an independent safety signal.

DNS and Email

Nameservers are provided by Cloudflare, indicating managed DNS hosting. No MX record was found. A conventional explicit inbound-mail route is not configured. TXT records include verification markers for Google. Such markers may also remain after a service stops being used. DNSSEC signatures were not detected, so this additional DNS authenticity protection is not confirmed. The lowest observed DNS TTL is 300 seconds.

TLS and Certificates

The certificate uses an RSA 2048-bit public key, offering broad client compatibility. The server supplied a complete certificate chain. No organization name is present in the certificate; the available fields are consistent with domain validation. The certificate was issued by Let's Encrypt, commonly associated with automated certificate services. The certificate's total validity is about 89 days, consistent with a short renewal cycle.

HTTP and Browser Security

The Server header exposes the software version: Apache/2.4.38 (Debian). This makes version-targeted checks easier, but is not proof of an exploitable vulnerability.
