WebGlomerular filtration rate (GFR) was measured directly by plasma iohexol disappearance. The equations were derived to estimate GFR using either serum creatinine or IFCC … WebGFR (glomerular filtration rate) is equal to the total of the filtration rates of the functioning nephrons in the kidney. GFR is considered the optimal way to measure kidney function, which in conjunction with albuminuria, can help determine the extent of CKD in an individual. The level of GFR and its magnitude of change over time are vital to:

WebCystatin C is freely filtered at the glomerulus. After filtration, Cystatin C is reabsorbed and catabolized by the tubular epithelial cells, with only small amounts excreted in the urine. Cystatin C levels are therefore measured not in the urine, but in the bloodstream. Equations have been developed linking estimated GFR to serum cystatin C levels. WebBecause mild and moderate kidney injury is poorly inferred from serum creatinine alone, NIDDK strongly encourages clinical laboratories to routinely estimate glomerular …
