Which is the normal serum creatinine range?

The normal serum creatinine range for most adults is generally accepted to be approximately 0.6 to 1.2 mg/dL, but it can sometimes vary slightly depending on the laboratory reference values and individual factors such as muscle mass, age, and sex. The choice that reflects a range that encompasses typical normal values can be seen as widely accepted.

The selected range of 0.5-1.5 mg/dL is appropriate because it includes the more frequently cited average normal range while allowing for individual variations that may occur in different populations. Values below this range may indicate issues such as low muscle mass or certain renal conditions, while consistent values above the upper limit could signify impaired kidney function.

In the context of the other options provided, the correct range is distinguishable as it represents a realistic overview of acceptable serum creatinine levels in the general adult population. Other ranges either fall outside of this generally accepted normal limit or include values that are indicative of renal dysfunction.
