Liver Function Test (LFT)

What is a Liver Function Test?

A Liver Function Test (LFT) — also called a hepatic panel — is a group of blood tests that assess how well your liver is working. The liver plays a vital role in detoxification, protein synthesis, bile production, and metabolism. When liver cells are damaged or inflamed, they release specific enzymes into the bloodstream that LFT panels measure.

At Red Bio Path Labs in Patna, our LFT panel is processed on calibrated auto-analyzers with quality controls at every step, ensuring results your hepatologist or general physician can rely on.

Why is an LFT Done?

Your doctor may recommend an LFT for several reasons:

• Suspected liver disease — hepatitis, fatty liver, cirrhosis, or jaundice
• Alcohol use monitoring — chronic alcohol consumption elevates liver enzymes
• Medication review — statins, antibiotics, and other drugs can affect the liver
• Diabetes and obesity screening — non-alcoholic fatty liver disease (NAFLD) is increasingly common
• Pre-operative assessment — evaluating liver function before surgery
• Routine health checkups — especially in patients with metabolic risk factors

Preparation Instructions

1. Fasting for 8–12 hours is recommended for the most accurate results
2. Avoid alcohol for at least 24 hours before the test
3. Inform your doctor about all medications and herbal supplements
4. Avoid strenuous exercise the day before testing, as it can temporarily raise AST levels
5. Stay hydrated with water during the fasting period

Parameters Included

Our comprehensive LFT panel covers the key markers used by clinicians to assess liver health and guide further investigation when abnormalities are found.

Understanding Your Results

Elevated ALT and AST suggest liver cell injury. Raised ALP and GGT may indicate bile duct problems. High bilirubin levels can cause jaundice (yellowing of skin and eyes). Low albumin may reflect chronic liver disease or malnutrition. Your doctor will interpret results in context of your symptoms, imaging, and medical history.

Normal Ranges (Adults)

| Parameter | Typical Range | |-----------|--------------| | ALT (SGPT) | 7 – 56 U/L | | AST (SGOT) | 10 – 40 U/L | | ALP | 44 – 147 U/L | | Total Bilirubin | 0.1 – 1.2 mg/dL | | Direct Bilirubin | 0.0 – 0.3 mg/dL | | Total Protein | 6.0 – 8.3 g/dL | | Albumin | 3.5 – 5.0 g/dL | | GGT | 9 – 48 U/L |

Reference ranges may vary. Always discuss your report with a qualified physician.
