What is Alanine Aminotransferase (ALT)?
Alanine Aminotransferase is measured as part of a liver function panel. Your ALT (liver enzyme) is normal — no signs of liver cell damage.
What does a high Alanine Aminotransferase mean?
Elevated ALT indicates liver cell stress or damage. Common causes include fatty liver disease, hepatitis, alcohol, or certain medications. The degree of elevation matters — mildly elevated vs. 10x normal are very different situations.
If markedly elevated: Your ALT is critically elevated, suggesting significant liver injury. Please seek medical evaluation promptly.
What does a low Alanine Aminotransferase mean?
Low ALT is rarely clinically significant.
