What is the normal range for creatinine in mg/dL?

• A. 0.7-1.3
• B. 0.5-1.0
• C. 1.2-1.6
• D. 0.9-1.4

Answer: (A)

Creatinine level reflects how well the kidneys are filtering waste from the blood. In adults, the normal serum creatinine range is about 0.7 to 1.3 mg/dL, with men typically toward the higher end due to greater muscle mass and women toward the lower end. This range is what NBRC practice items use as the standard reference. Values above 1.3 mg/dL suggest reduced kidney function or dehydration, while values below 0.7 mg/dL are uncommon and may indicate lower muscle mass or reduced creatinine production. The other options fall outside the typical adult reference range, so they don’t match the standard NBRC value.
