for quantification of BRT. In addition, in another study a liquid chromatography-tandem mass spectrometry technique (LC-MS/MS) was developed for the simultaneous determination of BRT and methotrexate in biological fluids [ 4 ]. The mobile phase used

treatment, which is tedious to operate; enzyme linked immunosorbent assay (ELISA) has cross reaction and poor specificity; the sensitivity of HPLC is low. Bollini et al present a sensitive, specific LC-MS/MS assay for thebaine in urine [ 15 ]. Kikura
