Essential Blood Tests for Liver and Kidney Function

Liver Function Overview

Liver function tests help assess liver health, detect inflammation, infections, or damage due to alcohol, hepatitis, or medications.

ALT (Alanine Aminotransferase)

Elevated ALT levels indicate liver inflammation or damage, often from hepatitis, fatty liver, or alcohol-related liver disease.

AST (Aspartate Aminotransferase)

AST rises with liver or muscle damage. It is often evaluated with ALT for a clearer liver function picture.

ALP (Alkaline Phosphatase)

High ALP may indicate bile duct blockage, liver disease, or bone disorders. Combined with other tests for accurate results.

Bilirubin

High bilirubin causes jaundice and may signal liver dysfunction or bile duct obstruction. It measures liver’s ability to process waste.

Creatinine

Creatinine levels reflect kidney function. High levels suggest impaired kidney filtering ability or chronic kidney disease.
