Analytical Services for Preclinical and Research Applications

Birdrock Laboratories, located in San Diego, is an accredited analytical laboratory certified by CLIA and COLA. With a wealth of experience in clinical diagnostics, we recognize the significance of analytical services for early-stage companies. We understand that the expenses associated with such services can be daunting, particularly for those with constrained budgets. Our primary objective is to deliver top-notch, hands-on laboratory solutions at affordable rates.

Our services are designed to cater to the specific requirements of the biotechnology and medical device sectors, with a particular focus on supporting preclinical and research endeavors.

Our Lab

Urine Drug Testing for the healthcare professional is more than just a useful tool in pain management. It provides additional valuable objective information to guide and assist in the diagnostic therapeutic decision-making process. Reports from the results of the urine drug tests provide confirmation of the agreed upon treatment plan. Testing can provide the patients proof of adherence and compliance. Testing can also diagnose a possible relapse or drug misuse, which would then warrant and set the stage for a firm conversation with your patient about their medications.

Birdrock Laboratory utilizes the most sophisticated platform for urine testing. We provide an industry standard immunoassay testing, which is fast and used as the preferred initial test. But we go further, running the urine through mass spectrometry as an additional confirmatory test to help eliminate the false-positives and negatives. These are common issues when using the immunoassay testing alone. Birdrock Labs services are designed to better improve patient care by providing the tools to assist the healthcare professional to advocate on the patients behalf.
