What is PTC Laboratories?

Updated

PTC Laboratories is a genetic testing laboratory based in Las Cruces, New Mexico, USA, founded in 1996. It operates internationally and offers DNA testing in several areas: relationship testing, forensic DNA testing, medication metabolism, and disaster management. If you need a DNA test for paternity, family relationship verification, forensic purposes, or related applications, PTC is one of the labs that handles such cases — including through a network of more than 2,000 collection locations across the United States.

What services does PTC Laboratories provide?

Based on the lab's own description, its work falls into four main areas:

Service area What it covers
Relationship testing DNA testing to establish biological relationships, such as paternity
Forensic DNA testing DNA analysis for forensic applications
Medication metabolism Genetic testing related to how the body processes medications
Disaster management DNA identification work connected to disaster response

The site groups its offerings under headings including "DNA Services and Products," "Forensic DNA Testing," "Relationship Testing," and "More DNA Testing Services," so the exact menu of individual tests is best confirmed on those pages.

Who does PTC serve?

PTC describes three broad customer types:

  • Private entities — organizations that contract with the lab for testing
  • Government agencies — public bodies using its DNA services
  • Individuals — people arranging their own tests, including internationally

For relationship testing in particular, the lab says it performs DNA paternity testing worldwide through contracts with these groups.

How does sample collection work?

PTC states that it handles DNA cases from over 2,000 collection locations throughout the United States. In practice, this means you generally do not need to travel to the lab in New Mexico — a case can typically be routed through a local collection site, with the sample sent to PTC for analysis. If you are outside the United States, the lab's international contract work is the relevant path, and you would need to confirm with PTC directly how collection is arranged in your country.

What to check before choosing PTC

  • Test type fit — confirm the lab offers the specific test you need (paternity, other relationship questions, forensic work, or medication metabolism testing), since these are distinct service lines.
  • Collection logistics — ask whether there is a collection location near you, or how international collection is handled.
  • Pricing and turnaround — the site has a dedicated Pricing page; current costs, payment options, and processing times should be taken from there rather than assumed.
  • Legal vs. personal use — for relationship testing, whether results need to meet a legal standard affects the collection process, so state your purpose when you inquire.

The most reliable next step is to visit ptclabs.com directly, review the service page matching your need, and contact the lab to confirm availability, cost, and collection arrangements for your location.
