What Is This Test?

Why this test is performed?
Helps detect and monitor hepatitis, fatty liver, alcohol-related liver disease, jaundice, gallbladder and bile duct problems and side-effects of medicines. It is part of most routine health check-ups.
Who should take this test?
Jaundice, nausea, abdominal pain or swelling, alcohol use, fatty liver, hepatitis risk, or people on long-term medicines.
