Direct Bilirubin Measurement

Preferred Label : Direct Bilirubin Measurement;

NCIt related terms : BILDIR; Direct Bilirubin;

NCIt definition : The bilirubin is bound to glucuronide to form conjugated bilirubin (direct bilirubin). Direct Bilirubin measurement is accomplished by a colorimetric method. Direct Bilirubin in biological fluids reacts with sulfanilic acid at acidic pH to produce a red colored complex. The optical density of produced color has a direct relationship with Direct Bilirubin concentration in the solution.;

Alternative definition : CDISC: A measurement of the conjugated or water-soluble bilirubin in a biological specimen.;
