About PinPoint Testing, LLC

Consultants for Laboratory and Clinical Drug Tests
PinPoint Testing, LLC offers a simple and effective approach for drug tests.
As synthetic drugs emerged, public and commercial laboratories struggled with detection; the founders of PinPoint Testing, LLC became the industry experts and pioneers in synthetic drug detection. As they flexed their muscles as industry legal experts and widely published subject matter experts they also developed analytical solutions to a true problem: detecting large panels of recognized and emerging drugs in clinical samples. Detection of emerging drugs requires day-to-day vigilance, and the development and validation of new analytical tools is a full time job best handled by the experts.

Let PinPoint Testing, LLC keep you and your laboratory on the cutting edge of toxicology with an unprecedented and cost effective testing menu offering.

PinPoint Testing Abilities

LC-MS/MS Drug Test Consultants

Our scientists are experts in designing and implementing customized tools to detect large panels of drugs simultaneously using LC-MS/MS in human urine and blood specimens. In collaboration with Cayman Chemical Company, the customized production of user-friendly ToxBox® products enables private and public laboratories to quickly establish on-site drug testing.

We offer a broad spectrum of LC-MS/MS drug test Consulting Services, which includes planning of customized Tox Box® products, training of laboratory staff, assistance with laboratory accreditation, and expert witness testimony. Training includes hosting your laboratory staff in our own accredited facility coupled with on-site assistance in your laboratory to ensure rapid implementation of customized tools on your LC-MS/MS. Our goal is to rapidly transition your laboratory to on-line testing for substance abuse drugs and other xenobiotics in human samples relying on the strong analytical, chemical and toxicological expertise of our scientists.

LC-MS/MS drug tests are becoming standard practice for laboratories but often having a sufficient number of trained personnel is an issue. PinPoint Testing, LLC can simplify the testing procedures and train personnel in the new technique. Having trained personnel is always an issue, but simplified procedures minimizes the problem.
