Use

This test is used to evaluate kidney function by measuring the level of creatinine in serum or plasma and estimating the glomerular filtration rate (eGFR) using the CKD-EPI equation. The eGFR is adjusted for a body surface area of 1.73 square meters and provides an assessment of kidney filtration function. This is useful in diagnosing and monitoring acute kidney injury, chronic kidney disease, and acute glomerular damage. It is most accurate in individuals 18 years and older and less reliable in patients with unusual muscle mass or those on specific medications affecting creatinine metabolism.
