FAQs on Liver Function Test
What are liver function tests?
LFTs are a set of liver protein tests for checking for abnormal liver function. These tests involve albumin levels and total protein levels in the blood. ALP (alkaline phosphatase), ALT (alanine transaminase), AST (aspartate aminotransferase), LDH, and gamma-glutamyl transferase (GGT).
What is the purpose of a liver function test?
A liver panel is essential for detecting chronic or acute types of hepatitis. These are also for monitoring therapy of liver diseases to show if treatment is effective, checking cirrhosis, drug toxicity and side effects of certain medicines.
Why do I need liver function testing?
If you are undergoing long-term therapy for chronic disease or acute hepatic infection or have experienced jaundice, nausea and vomiting, diarrhoea, abdominal pain, dark-coloured urine, pale stool, or fatigue, then LFTs are important.
What happens during a liver function test?
A blood sample is withdrawn from your vein, stored in a tube, and then further sent for analysis.
What do the results mean?
The results either report elevation or demotion of enzymes/proteins in the liver. The doctor must carefully differentially diagnose your condition according to enzyme levels and aid in drug therapy selection.
