Know More About This Test

LFT is a group of blood tests assessing liver enzymes, proteins, and bilirubin levels. It evaluates liver health, detects liver injury, and monitors disease progression or treatment response.

The liver performs vital metabolic and detoxification functions, and early damage may be asymptomatic.

Why Is This Test Recommended?

This test is recommended for:

• Suspected liver disease
• Alcohol use monitoring
• Drug toxicity evaluation
• Viral hepatitis screening

Understanding LFT

Abnormal enzyme levels indicate liver cell injury, bile duct obstruction, or impaired synthetic function.

• Jaundice (yellowing of skin and eyes)
• Fatigue
• Abdominal pain
• Dark urine

How Do I Prepare for the Test?

Fasting is often recommended for accurate results.

How Is the Test Performed?

A blood sample is collected from a vein in your arm.

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.
