APS 2012 Booth Presentation: Patterns of Opioid Metabolites in Urine - The Buprenorphine Story


Blood is an ideal specimen for evaluating adherence to therapy in patients who cannot provide urine, to support pharmacokinetic studies, and to reduce the opportunity for specimen adulteration. However, testing for drugs in blood with traditional immunoassay-based technologies is associated with many limitations in sensitivity and specificity. This presentation will describe the improvements in sensitivity and specificity gained by a novel mass spectrometric approach to drug screening with blood.

Originally presented on May 17, 2012, in Honolulu, Hawaii.
