ABSTRACT:
A colorimetric assay for the determination of conjugated, unconjugated or total bilirubin in biological fluids can be carried out with an improved analytical element. This element comprises a support having thereon a substantially gelatin-free mordant layer comprising a positively-charged interactive mordant having at least one binding site for bilirubin, a radiation-blocking layer, and a porous spreading layer. This element does not contain any colorimetric or fluorometric interactive compositions for bilirubin other than the mordant.
