Liver Function Test (LFT) in Delhi

Do I need to fast for an LFT?

Yes, 8–10 hours of fasting is typically recommended for the most accurate results, particularly when the test is combined with other panels like lipid profile or glucose.

What are the most common causes of mildly elevated liver enzymes?

Fatty liver disease, recent alcohol consumption, certain medications, and even vigorous exercise can all cause mild, often temporary elevations in liver enzymes.

Can LFT results be normal even with liver disease present?

Yes, some chronic liver conditions, particularly in early stages of cirrhosis, can show near-normal LFT results, which is why imaging or further specialized tests are sometimes needed alongside blood work.

How often should LFTs be repeated if I'm on long-term medication?

This varies by medication, but many doctors recommend checking liver enzymes every 3–6 months for drugs known to affect the liver, or sooner if you develop symptoms.
