What is a normal direct bilirubin level?
The short answer
A typical US lab calls direct bilirubin normal up to 0.3 mg/dL. That range exists to catch disease, not to describe your best.
Nobody we follow has said what your Direct Bilirubin should be. It comes up on the shows, but never with a number.
What Direct Bilirubin measures
The portion of bilirubin your liver has already processed.
When it runs high, the problem sits in bile flow more often than in the breakdown of red cells.
