An ALT (Alanine Aminotransferase) test measures the level of this enzyme in your blood. ALT is found primarily in the liver, making it one of the most specific markers for liver cell damage.
What This Test Measures
ALT (SGPT):
An enzyme concentrated in liver cells. When liver cells are damaged or inflamed, ALT leaks into the bloodstream, causing elevated levels. ALT is more specific to the liver than AST.
Reference Ranges
• Men: 7-56 U/L
• Women: 7-45 U/L
Who Should Consider This Test
• Evaluating liver function
• Monitoring hepatitis B or C
• Suspected fatty liver disease (NAFLD)
• Monitoring medications that may affect liver
• Evaluating elevated liver enzymes found on other tests
• Routine screening for those at risk for liver disease
What Elevated ALT May Indicate
Liver Conditions:
• Hepatitis (viral, alcoholic, autoimmune)
• Non-alcoholic fatty liver disease (NAFLD)
• Cirrhosis
• Liver damage from medications or supplements
• Drug-induced liver injury
Degree of Elevation:
• Mild (2-3x normal): Fatty liver, chronic hepatitis, medications
• Moderate (3-10x normal): Acute hepatitis, toxic exposure
• Severe (>10x normal): Acute viral hepatitis, drug toxicity, ischemic liver injury
