Direct and Indirect Bilirubin Test Overview

A direct and indirect bilirubin test are jointly used by doctors to understand the total bilirubin levels in your body. Bilirubin is formed by the breaking down of red blood cells. The liver takes the bilirubin from the blood and changes its chemical composition. This allows bilirubin to be excreted out of the body with stool.

If you have an abnormally high level of bilirubin in your blood, it could indicate problems with your liver or kidneys. A direct and indirect bilirubin test can help doctors diagnose liver and kidney damage, which if left untreated could lead to serious health complications.
