Possibility of Conjugated Bilirubin Being More Than Total Bilirubin

Increase in serum conjugated bilirubin than total bilirubin is rare. Further investigations to
identify the source of interference needs to be assessed for the interpretation and reporting.
Our communication demonstrates that paraproteins specially IgM was the source of
interference and should be thought of and analysed in case of such abnormal fin
estimation of bilirubin.
