Diagnostic device for rapid determination of buprenorphine

摘要

This invention relates to a method of detecting buprenorphine in biological fluids (especially urine), and to a device and kit which use chromatographically mobile reagents labelled with gold clusters. The method involves contacting urine sequentially with anti-buprenorphine antibodies labelled with gold clusters and with buprenorphine immobilised on a porous support, in order to detect the presence of buprenorphine in the sample by means of a competitive reaction. The device according to the invention consists of a rack which can be filled with a number of strips; the kit consists of a box with separate sections for the strips and a separate compartment which holds the rack.
