What is the normal creatinine level for adults?

The normal creatinine level for adults is indeed generally accepted to be within the range of 0.8 to 1.5 mg/dl. Creatinine is a waste product produced by muscle metabolism and is typically excreted through the kidneys. Its measurement in the blood is a useful indicator of renal function.

This range can vary based on various factors such as age, gender, and body mass. However, the established norms for adult men typically hover at the higher end of this range, while women may fall slightly lower due to differences in muscle mass. Consequently, choice C encompasses an appropriate norm that aligns with accepted clinical references for adults, suggesting a reliable measure for evaluating kidney health and function. This makes it the correct choice when one's aim is to assess normal adult creatinine levels accurately.
