SGPT / ALT (Alanine Aminotransferase)
SGPT (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.

What is the SGPT Test?
SGPT (Serum Glutamic Pyruvic Transaminase), also known as ALT (Alanine Aminotransferase), is a liver enzyme primarily found in liver cells. When liver cells are damaged, SGPT leaks into the bloodstream. It's considered the most liver-specific enzyme — elevated SGPT almost always indicates liver cell injury, whether from hepatitis, fatty liver, medications, or alcohol.
Why Should You Take This Test?
Primary marker for liver cell injury. Often ordered with SGOT for complete liver enzyme profile.
Who Should Get Tested?
Liver Health Screening
Most specific single marker of liver cell damage.
On Hepatotoxic Drugs
Monitoring for drug-induced liver injury.
Alcohol Users
Regular liver enzyme monitoring.
Overweight Individuals
Screening for fatty liver disease.
