Laboratory Evaluation of Kidney Disease

Recommended eGFR equations will be changing. Once guidance is adopted, we will update this content accordingly.

Laboratory measurement and reporting are critical to promoting early detection and management of chronic kidney disease (CKD). NIDDK's major laboratory-related efforts address GFR, urine albumin, and cystatin C.

Glomerular Filtration Rate (GFR)

NIDDK encourages routine reporting of estimated GFR with all serum creatinine determinations for patients age 18 and older, when appropriate and feasible. Learn more about estimating and reporting GFR.

Urine Albumin Standardization

Urine albumin measurement and reporting is critical to the early detection and treatment of chronic kidney disease. Read about urine albumin standardization issues.

Frequently Asked Questions

Estimated GFR is a key method for identifying people with chronic kidney disease. Read why eGFR provides a more clinically useful measure of kidney function than serum creatinine alone.
