Hepatitis Alanine Aminotransferase (ALT) reaches how much

Under normal circumstances, the reference range for alanine aminotransferase (ALT) in patients with hepatitis is generally 0-40 U/L. Levels exceeding 40 U/L suggest abnormal results and may indicate liver cell damage. If concerned, it is recommended to seek medical advice in advance. Detailed analysis is as follows:

When ALT levels range between 40-120 U/L, this typically indicates a mild increase, which may be caused by early-stage hepatitis, mild liver cell inflammation, or increased metabolic burden on the liver. Some patients may not exhibit obvious symptoms, and further evaluation with hepatitis B and C virus testing and liver ultrasound is needed to determine the underlying cause.

If ALT exceeds 120 U/L, especially reaching above 200 U/L, it indicates a moderate to severe elevation, suggesting significant liver cell damage, possibly during an active phase of hepatitis. This is often accompanied by symptoms such as fatigue, decreased appetite, and jaundice. Prompt antiviral and liver-protective treatments are necessary to prevent progression to cirrhosis.

The degree of ALT elevation does not always correlate directly with the severity of liver damage. Comprehensive evaluation combining other liver function parameters and etiological tests is required for accurate assessment.
