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-LabTest 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.
