A METHOD FOR PREPARING A TEST DEVICE FOR DETECTING BILIRUBIN IN A URINE SAMPLE

摘要

A test composition, device, and method for detecting bilirubin in urine. The test composition includes a diazonium compound reactable with urinary bilirubin to produce a color change, an acid pH producing constituent, and a potentiating agent for the test reaction. The potentiating agent is an adduct of a ureido compound and an organic sulfonic acid or a salt form thereof. Particularly useful as the ureido constituent of the adduct are urea and substituted and unsubstituted cyclic ureido compounds, particularly those belonging to the xanthine family. The test device comprises a carrier, such as an absorbent matrix, incorporated with the test composition. The test method is carried out by contacting a urine test sample with the test composition and observing any resulting colorimetric response.[US4038031A]
