The measurement of direct (conjugated) bilirubin used in conjunction with the measurement of total bilirubin can give an estimate of the amount of unconjugated (indirect) bilirubin present. The relative amounts of direct and indirect bilirubin in the circulation are of value in helping to determine likely causes of raised total bilirubin.
