At these levels, unconjugated bilirubin exceeds the amount of available albumin to bind it. Direct bilirubin correlates with conjugated bilirubin but tends to overestimate actual conjugated bilirubin, as it includes both the conjugated bilirubin and bilirubin covalently bound to albumin (delta-bilirubin). If you are on medicines like penicillin G, Phenobarbital, theophylline, or furosemide, the recommendation is to consult your doctor before the Bilirubin test, to confirm if you have to stop the medications or not.
