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.

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 ₹880 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 SGOT (AST) may reflect liver-cell stress or injury and can also rise with muscle injury. A raised SGPT (ALT) is a fairly specific marker of liver-cell stress or injury, including fatty liver. A raised GGT may relate to the liver or bile ducts and can rise with alcohol use or certain medicines. 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 SGOT is generally not clinically significant. A low SGPT is generally not clinically significant. A low GGT 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.

What this test measures
11 parameters in the Liver Function Test (LFT)
The Liver Function Test (LFT) reports the following parameters. These are this lab’s own reference ranges: the same ones your result is reported against, not a generic table. Adult values are shown; where a range differs by age, the range for your age is applied automatically when the result is released. Always read results with your doctor.

Understanding your results
What high or low results may mean
For the 7 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.
Your liver
The organ that processes what you eat and drink, filters your blood and makes proteins. These markers are enzymes and pigments that rise when it is working hard or under strain.
Parameter
If higher than range
If lower than range
SGOT / AST (Aspartate Aminotransferase)
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 (Alanine Transaminase)
A raised SGPT (ALT) is a fairly specific marker of liver-cell stress or injury, including fatty liver.
A low SGPT is generally not clinically significant.
GGT (Gamma-Glutamyl Transferase)
A raised GGT may relate to the liver or bile ducts and can rise with alcohol use or certain medicines.
A low GGT is not clinically significant.
ALP (Alkaline Phosphatase)
A raised alkaline phosphatase may relate to the liver, bile ducts, or bone, and is normally higher in growing children and in pregnancy.
A low alkaline phosphatase is uncommon and usually not a concern.
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.
Globulin
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.
Reference ranges vary by laboratory, age, sex and method, and results must be interpreted together and in the context of your health. This information is educational and is not a diagnosis or medical advice, always discuss your report with your doctor.
