Liver function tests (LFTs) check enzymes, proteins, and bilirubin to assess your liver’s health. But interpreting the patterns can be confusing. This page explains the basics and how AI Lab Result Interpretation helps make them clear.
Important: Abnormal liver enzymes don’t always mean serious disease. Medications, alcohol, or temporary illness can affect values. Always consult your clinician.
Key markers
- ALT (Alanine transaminase) — often rises with liver inflammation.
- AST (Aspartate transaminase) — enzyme found in liver and muscle.
- ALP (Alkaline phosphatase) — linked to bile ducts and bone health.
- Bilirubin — buildup can cause jaundice.
- Albumin/Total Protein — reflect nutrition and liver synthesis function.
Common patterns
- High ALT + AST → possible hepatitis or fatty liver.
- High ALP + bilirubin → possible bile duct obstruction.
- Low albumin → possible chronic liver disease.
