LDH increases with liver damage due to cancer, cirrhosis, chronic viral hepatitis and is described as what kind of lab value?

LDH increases with liver damage due to cancer, cirrhosis, chronic viral hepatitis and is described as what kind of lab value?

• A. ALT
• B. AST
• C. LDH
• D. GGTP

Answer: (C)

LDH is a non-specific marker of tissue injury. It is present in many tissues throughout the body, so when cells are damaged—whether in the liver, heart, red blood cells, muscles, or elsewhere—LDH leaks into the bloodstream and rises. In liver diseases such as cancer, cirrhosis, or chronic viral hepatitis, LDH can be elevated, but it does not point to the liver specifically. That contrasts with ALT and AST, which are more liver-specific enzymes, and with GGTP, which is more associated with biliary or cholestatic processes. So the best description for this scenario is that LDH is a nonspecific lab value reflecting general tissue injury rather than a liver-specific test.
