What is the typical range for creatinine levels in the blood?

The typical range for creatinine levels in the blood is significant for evaluating kidney function. In healthy adults, normal serum creatinine levels typically fall between 0.5 and 1.5 mg/dL. This range can vary slightly depending on factors like muscle mass, age, and gender, but the majority of clinical references agree on this range for general assessments.

Creatinine is a byproduct of muscle metabolism and is usually produced at a fairly constant rate. The kidneys filter creatinine out of the blood, and the levels of creatinine can indicate how well the kidneys are functioning.

When interpreting these values, elevated levels can suggest impaired kidney function, while lower levels usually indicate good kidney health. Recognizing and understanding the typical creatinine levels helps healthcare professionals make informed decisions related to renal function, which is crucial in fields such as radiology, particularly when considering imaging procedures that may require contrast agents.
