Bilirubin (Direct)
Direct bilirubin mainly reflects the bilirubin the liver has already processed, known as conjugated bilirubin. It is water-soluble and can be measured directly.
Why it matters: A higher level of conjugated bilirubin can appear when the body is having trouble clearing it, which might indicate a biliary or gallstone disease.
