Bile Acids, Total (Enzymatic) Test
This test measures the level of bile acids in the blood to help evaluate liver function and bile flow. It is also used to screen pregnant women for obstetric cholestasis.
About this test
Bile acids are processed by the liver, so their levels in serum serve as a marker of normal liver function. This test measures total bile acids and is described as being used to screen pregnant women for obstetric cholestasis, a liver condition that can arise during pregnancy.
The test is run on a 1 mL serum sample using an enzymatic method.
