LONG-TERM ADHERENCE TESTING TO HELP PREVENT HIV INFECTION

Our dried blood spot (DBS) objective adherence test measures levels of tenofovir-diphosphate in the blood via a liquid chromatography–mass spectrometry test. The test indicates the average level of PrEP adherence for the patient over the past several weeks – all through a simple fingerstick.

The DBS adherence test can be collected at-home or in-clinic by either the patient or provider. After the sample is collected, it is then shipped to a CAP accredited, CLIA licensed laboratory for processing. Within a few days, the provider receives the test result and interpretation. If the patient is non-adherent, the provider or PrEP navigator can work with the patient on an effective intervention.

Research shows that adherence testing and targeted counseling leads to a 50% improvement in PrEP adherence.¹

Objective adherence testing fits seamlessly into clinical workflow and enhances HIV care, providing actionable adherence insights without any extra clinical visits.
