Hepatitis is diagnosed when liver enzymes are how many times the normal value?

• A. 1-1.5x
• B. 4-5x
• C. 2-3x
• D. 6-7x

Answer: (C)

Hepatocellular injury raises liver enzymes, and the level often used to flag hepatitis is when ALT or AST climbs to about two to three times the upper limit of normal. This range reflects a meaningful amount of liver cell injury suggesting hepatitis, whereas only mild elevations (around 1–1.5 times) can occur with many minor issues and aren’t as diagnostic. Larger increases, like four to five times or higher, can happen with more acute or severe liver damage, but the typical threshold clinicians use to consider hepatitis is in the 2–3 times range. Remember that ALT is more liver-specific than AST, and in true hepatitis you’d expect these enzymes to be elevated above normal, with context from symptoms and other tests guiding the diagnosis.
