What is the lowest value of the normal creatinine range?

The normal range for serum creatinine levels is generally established to assess kidney function, with typical values varying based on factors such as age, sex, and muscle mass. In most laboratory contexts, the lower limit of the normal creatinine range for adults is approximately 50 umol/L. This value represents a baseline that indicates proper kidney function, as creatinine is a waste product of muscle metabolism excreted by the kidneys. Values lower than this threshold could suggest decreased muscle mass or could indicate other conditions that may require further investigation.

Understanding the range can help healthcare professionals interpret laboratory results accurately and make informed decisions regarding patient care.
