Liver function tests (LFTs) are blood tests that measure various substances produced by the liver, such as enzymes and proteins. These tests help assess liver health, detect liver diseases like hepatitis or cirrhosis, and monitor the effects of medications on the liver. Common components of LFTs include:

• Alanine aminotransferase (ALT): An enzyme found primarily in the liver; elevated levels may indicate liver damage.

• Aspartate aminotransferase (AST): An enzyme present in the liver and other organs; high levels can suggest liver or muscle damage.

• Alkaline phosphatase (ALP): An enzyme related to the bile ducts; increased levels may point to bile duct obstructions.

• Gamma-glutamyl transferase (GGT): An enzyme involved in bile production; elevated levels can indicate liver or bile duct issues.

• Bilirubin: A waste product from the breakdown of red blood cells; high levels can lead to jaundice and suggest liver dysfunction.

• Albumin: A protein made by the liver; low levels may indicate liver disease or malnutrition.

These tests provide valuable information about liver function and can help healthcare providers diagnose and manage liver-related conditions. It’s important to note that abnormal results may require further testing to determine the underlying cause.
