WebTotal bilirubin in serum is composed of direct (conjugated) bilirubin and indirect (unconjugated) bilirubin. Since the introduction of the diazo method for bilirubin determination by Ehrlich in 1883,1 several modifications have been proposed to enhance the reaction. The primary reason for these WebThe indirect (or unconjugated) bilirubin can then be calculated by subtracting the direct bilirubin from the total bilirubin. Slide 6: In addition to the diazo methods, there are several other methods for measuring bilirubin. The first of these listed here utilizes a slide‐based method produced by Ortho Clinical Diagnostics on Vitros analyzers.
