Liver Function Test (LFT)
A standard liver panel measuring enzymes, bilirubin, and proteins—for screening liver health and detecting damage.
Test Information
Reports In
Same day (5-6 hours)
Parameters
8
Requisites
Blood Sample
Sample Type
Blood
Measures
SGOT (AST), SGPT (ALT), alkaline phosphatase, total bilirubin, direct bilirubin, total protein, albumin, and globulin—key markers of liver function and cell integrity.
Identifies
Liver cell damage (elevated SGOT/SGPT), fatty liver, hepatitis, jaundice (elevated bilirubin), cirrhosis (low albumin), and bile duct obstruction.
What is the LFT Test?
The Liver Function Test (LFT) is a panel of blood tests that assess how well your liver is working. It measures liver enzymes (SGPT, SGOT, ALP, GGT), proteins (total protein, albumin, globulin), and bilirubin. Together, these markers reveal liver cell damage, bile flow obstruction, and the liver's ability to produce essential proteins.
Why Should You Take This Test?
Fatty liver is increasingly common in India—linked to obesity, diabetes, and sedentary lifestyle. LFT detects liver damage early. It is also essential before starting medications that can affect the liver, and for monitoring hepatitis.
Who Should Get Tested?
Alcohol Consumers
Even moderate drinking can damage the liver over time.
On Long-Term Medications
Many drugs are processed by and can damage the liver.
Overweight / Fatty Liver
NAFLD is the most common liver condition globally.
Hepatitis Patients
Regular monitoring of liver health.
Yellowing of Skin/Eyes
Jaundice is a key sign of liver problems.

BloodSGPT (ALT) is a liver enzyme released when liver cells are damaged. It is more liver-specific than SGOT. Elevated levels indicate hepatocellular injury from hepatitis, fatty liver, or toxins.
BloodSGOT (AST) is found in liver, heart, and muscle. Elevated with liver disease, heart attack, or muscle injury. Interpreted with SGPT – high SGPT/SGOT ratio suggests liver origin.
