Overview

The Creatinine, Serum test measures the amount of creatinine in your blood. Creatinine is a waste product produced by normal muscle metabolism and is filtered out of the body by the kidneys. Because the kidneys are responsible for removing creatinine from the bloodstream, its level is a key indicator of kidney function. This test is commonly used to evaluate kidney health, diagnose kidney disorders, monitor chronic kidney disease (CKD), and assess the effectiveness of treatments affecting kidney function. It is often performed as part of routine health checkups and kidney function tests.
