Do doctors check liver function when pregnant?

Yes, doctors typically check liver function during pregnancy. This is because certain liver conditions, such as intrahepatic cholestasis of pregnancy (ICP), can develop specifically during pregnancy and can affect the health of both the mother and the baby.

Routine prenatal care usually includes liver function tests as part of blood work, especially in the third trimester. However, if there are any signs or symptoms that suggest liver problems, such as itching, dark urine, or jaundice, the doctor may order liver tests earlier in pregnancy.

Common liver function tests during pregnancy include:

1. Alanine aminotransferase (ALT): This enzyme is found in liver cells. Elevated ALT levels in the blood can indicate liver damage or inflammation.

2. Aspartate aminotransferase (AST): Similar to ALT, AST is also an enzyme found in liver cells. Increased AST levels can signal liver injury.

3. Alkaline phosphatase (ALP): This enzyme is present in the liver and bones. Elevated ALP levels may indicate liver problems, bone disorders, or biliary obstruction.

4. Total bilirubin: Bilirubin is a yellow pigment produced when red blood cells break down. High bilirubin levels can suggest liver dysfunction or bile flow issues.

5. Direct bilirubin: This test measures the amount of conjugated bilirubin, which is a form of bilirubin that has been processed by the liver. Elevated direct bilirubin levels may indicate liver damage or biliary tract problems.

By monitoring liver function during pregnancy, doctors can identify any potential issues and take appropriate steps to ensure the well-being of the mother and the fetus.
