We are committed to the patients we serve and stand behind our results, knowing the impact they may have on someone's life. All samples are tested in-house and managed through a rigorous chain of custody process so that you can have peace of mind. Know that any sample we test is treated with the utmost care by skilled, educated, and experienced laboratory professionals—always!

Immuno-Analyzer Screens

These tests are typically performed in a clinical lab. These tests use light absorption to detect the presence of a particular drug class. As these assays are more sensitive and under higher quality controls in a lab setting compared to a point-of-care cup, these are a superior choice for screening purposes. This testing method is ideal for pre-employment, walk-in drug screening, and basic compliance testing. Follow-up confirmatory testing may be required to confirm the presence of a particular drug.

Our presumptive test offering screens up to 12 different drug classes in urine. You can select one or all the drug classes to meet your individual patient's needs.

Definitive Testing

This test, also known as confirmatory testing, is the gold standard of testing when looking to identify specific substances. Unlike point-of-care and immuno-assays that tell you potential drug classes, LCMSMS testing tells you precisely what is present. Confirmatory testing helps identify which drugs and metabolites are present with accurate quantitative information that depicts how much of each drug is detected. This testing uses known retention times and the molecular weights of compounds to quantify specific drugs accurately and confidently. With high sensitivity and precision, this testing can detect compounds for much longer than Immuno-assays, providing the ideal platform for medication monitoring and patient adherence.
