Critical — Seek Care

If you have yellow skin or eyes (jaundice), dark urine, clay-colored stool, or severe stomach pain, contact your doctor right away or seek urgent care. These could be signs of a serious liver or bile duct problem.

What It Measures

This lab test checks a type of bilirubin that your liver has already worked on. This processed bilirubin is ready to leave your body. It goes out with bile, which helps you digest food.

Why It's Ordered

Doctors check your direct bilirubin levels to see how your liver is doing. They also want to know if there are any clogs in the tubes that carry bile from your liver.

Reference Range

Reference ranges for direct bilirubin can vary between different laboratories. Your results should always be interpreted by your healthcare provider.
