Question

which of the following markers is an indication of impaired renal function?
a) creatinine
b) ast
c) alt
d) c - reactive protein

Explanation:

Creatinine is a waste product produced by muscle - metabolism and is primarily excreted by the kidneys. Elevated levels of creatinine in the blood are a common indicator of impaired renal function. AST (Aspartate aminotransferase) and ALT (Alanine aminotransferase) are mainly associated with liver function. C - reactive protein is a marker of inflammation in the body and not specific to renal function.

Answer:

a) Creatinine
