What is the normal Creatinine range for males?

• A. 0.6-1.2
• B. 0.7-1.3
• C. 0.5-1.0
• D. 0.8-1.4

Answer: (A)

Creatinine levels reflect how well the kidneys are filtering waste and are influenced by muscle mass, since creatinine is produced from muscle metabolism. In healthy adult males, the commonly cited normal serum range is about 0.6 to 1.2 mg/dL. This upper limit accounts for the higher muscle mass typical in men, which produces more creatinine. Some labs report slightly different ranges or use different units (for example, roughly 53–106 μmol/L in SI units), but 0.6–1.2 mg/dL is the standard reference for adult men. Values outside this range can indicate changes in kidney function, hydration, or muscle mass, though individual lab methods and populations can shift exact cutoffs.
