Clinical Utility

Elevated in acute hepatitis, chronic hepatitis, liver sclerosis, and cancer. Used to screen pregnant women for obstetric cholestasis. Symptoms of cholestasis include persistent itching in the third trimester of pregnancy and possible risks of the unborn baby including stillbirth, premature labor and bleeding. The frequency of obstetric cholestasis varies and is 1 in 100 pregnant European women vs. 1 in 10 pregnant South American women. Total bile acids levels are the most sensitive indicator for monitoring the effectiveness of interferon treatment of chronic hepatitis C patients.
