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.
The urine point of care test is currently available for research use. This test will allow providers to test patients’ urine and see their adherence results, all within a few minutes of their visit.
