Comparative StudyComparison of three commercial tests for buprenorphine screening in urine.
Rapid and sensitive tests for detecting buprenorphine and its metabolites for drug-screening situations have been long awaited. From the tests available, we have evaluated two on-site drugs-of-abuse testing devices using competitive binding immunoassays and one homogeneous enzyme immunoassay measured on an automated analyser. ⋯ Our results indicate that special care should be taken when selecting immunology-based point-of-care methods for measurement of buprenorphine.
