Frequently Asked Questions (FAQs)

1. Does abnormal LFT always mean liver disease? No, elevated liver enzymes can occur due to medications, recent alcohol use, or temporary conditions unrelated to serious liver disease.
2. Can medicines alter LFT? Yes, many medications including antibiotics, painkillers, and supplements can temporarily or permanently affect liver enzyme levels.
3. Is fasting required? Often recommended; fasting for 8-12 hours before the test helps ensure more accurate and reliable results.
4. Can LFT detect fatty liver? Suggestive, not confirmatory; abnormal LFT may indicate fatty liver, but imaging like ultrasound is needed for definitive diagnosis.
5. How often should it be repeated? As advised by your doctor based on your condition, risk factors, and whether you're on medications that affect the liver.
