✦ Synopsis

A radiounmunoassay developed for the determination of buprenorphine in human urine samples was examined for its applicability to screening post-race equine urine specimens The detection limit of the immunoassay in equine urine is 0 1 ng ml -1 Confirmation methods using liquid chromatography with electrochemical detection and gas chromatography-mass spectrometry have detection lumts of 02 ng ml -1 (unchanged buprenorphme and N-desalkylbuprenorphine) and 0 1 ng ml -1 (after hydrolysis), respectively The procedures were validated after 1n-field administration of 300 tg of buprenorphine to a test horse The procedures were also applied to screening a large number of random post-race equine urine samples
