GFR »

NKDEP promotes routine reporting of estimated glomerular filtration rate (eGFR) with all serum creatinine determinations for patients age 18 and older, when appropriate and feasible. Automatic reporting by laboratories can help increase provider use of eGFR — a clinically important and practical tool for CKD detection and management. Learn more about estimating and reporting GFR.

GFR Calculators »

NKDEP recommends the use of adult and pediatric GFR calculators to estimate kidney function for adults and children. Read more about GFR calculators to estimate kidney function for adults and children.

Urine Albumin »

NKDEP and the IFCC established a joint work group to standardize measurement and reporting of urine albumin. This effort has the potential to redefine how CKD is diagnosed and managed.

NKDEP's Lab Working Group (LWG), a group of professionals representing various sectors of the clinical laboratory community, is largely responsible for conceiving and implementing these efforts. Learn more about NKDEP’s efforts in urine albumin and the efforts of the LWG.

Update on Cystatin C »

Cystatin C is recognized as a useful marker for kidney damage. Several equations have been developed to estimate eGFR from serum cystatin C. Because cystatin C measurement procedures do not produce uniform results, the estimating equations are restricted for use only with results from the specific method used to develop them.
