About this test
A Liver Function Test (LFT) measures SGPT (ALT), SGOT (AST), bilirubin, alkaline phosphatase, total protein and albumin to assess how well your liver is working. It helps detect fatty liver, hepatitis, alcohol-related damage, bile-duct problems and the effect of medicines on the liver.
Clinical significance
Raised SGPT/SGOT point to liver-cell injury (fatty liver, hepatitis, alcohol or drug effects), while high bilirubin and alkaline phosphatase suggest jaundice or bile-flow obstruction. Low albumin can indicate long-standing liver disease. The pattern of abnormality helps your doctor pinpoint the cause and track treatment.

Frequently asked questions
What is the Liver Function Test (LFT)?
A Liver Function Test (LFT) measures SGPT (ALT), SGOT (AST), bilirubin, alkaline phosphatase, total protein and albumin to assess how well your liver is working. It helps detect fatty liver, hepatitis, alcohol-related damage, bile-duct problems and the effect of medicines on the liver.
What conditions does the Liver Function Test (LFT) detect?
The Liver Function Test (LFT) helps detect and monitor conditions including Fatty liver disease, Hepatitis, Liver cirrhosis, Jaundice / bile-duct obstruction, Drug-induced liver injury.
How should I prepare for the Liver Function Test (LFT)?
Avoid alcohol before test
What is the normal range for the Liver Function Test (LFT)?
SGPT (ALT): 7–56 U/L
SGOT (AST): 8–40 U/L
Total bilirubin: 0.3–1.2 mg/dL
Albumin: 3.5–5.2 g/dL Note: reference ranges may vary by laboratory and should be interpreted by your doctor in the context of your overall health.
How much does the Liver Function Test (LFT) cost?
The Liver Function Test (LFT) is available at ₹699 (MRP ₹2019) on PingMeDoc™ with free home sample collection. Prices are inclusive of sample collection charges.
What does a high result on the Liver Function Test (LFT) mean?
A raised total bilirubin can cause jaundice and may relate to the liver, bile ducts, or increased red-cell breakdown. A raised direct (conjugated) bilirubin may suggest a problem with the liver or with bile flow. A raised indirect (unconjugated) bilirubin may be seen with increased red-cell breakdown or with a common, harmless condition called Gilbert's syndrome. These are general associations, not a diagnosis — discuss your report with your doctor.
What does a low result on the Liver Function Test (LFT) mean?
A low bilirubin is not clinically significant. A low direct bilirubin is not clinically significant. A low indirect bilirubin is not clinically significant. A result outside the reference range should always be interpreted by your doctor in context.
Do I need to fast for an LFT?
An 8-hour fast is preferred for the most reliable result, especially if it is combined with a lipid profile or fasting sugar. Water is allowed, and you should avoid alcohol for 24–48 hours before the test.
What does a high SGPT or SGOT mean?
Raised SGPT (ALT) and SGOT (AST) indicate the liver cells are stressed or damaged — most commonly from fatty liver, hepatitis, alcohol or certain medicines. Mild elevations are common; your doctor interprets them with the rest of the panel.
Can fatty liver be detected by an LFT?
An LFT can flag fatty liver when liver enzymes are raised, but enzymes can be normal in early fatty liver. An ultrasound is often added for confirmation. Weight loss, exercise and limiting alcohol and sugar help reverse it.
Does the Liver Function Test (LFT) test require fasting?
No fasting is required for the Liver Function Test (LFT) test. You can eat and drink normally before sample collection.

Understanding your results
What high or low results may mean
For the 10 parameters below, here is what a value outside the reference range may be associated with. These are general, textbook associations — a result outside the range is not a diagnosis on its own.
Parameter
If higher than range
If lower than range
Total Bilirubin
A raised total bilirubin can cause jaundice and may relate to the liver, bile ducts, or increased red-cell breakdown.
A low bilirubin is not clinically significant.
Direct Bilirubin
A raised direct (conjugated) bilirubin may suggest a problem with the liver or with bile flow.
A low direct bilirubin is not clinically significant.
Indirect Bilirubin
A raised indirect (unconjugated) bilirubin may be seen with increased red-cell breakdown or with a common, harmless condition called Gilbert's syndrome.
A low indirect bilirubin is not clinically significant.
SGOT (AST)
A raised SGOT (AST) may reflect liver-cell stress or injury and can also rise with muscle injury.
A low SGOT is generally not clinically significant.
SGPT (ALT)
A raised SGPT (ALT) is a fairly specific marker of liver-cell stress or injury, including fatty liver.

Total Protein
A high total protein may be seen with dehydration or with certain chronic conditions.
A low total protein may relate to nutrition, the liver, or the kidneys.
Albumin
A high albumin is most often due to dehydration.
A low albumin may relate to nutrition, chronic illness, or the liver or kidneys.

A high globulin may be seen with chronic infection or inflammation and with some immune conditions.
A low globulin is uncommon and may relate to immune or kidney factors.
Gamma GT
