GFR Calculation

Glomerular filtration rate (GFR) can be calculated by measuring any chemical that has a steady level in the blood, and is freely filtered but neither reabsorbed nor secreted by the kidneys. The rate therefore measured is the quantity of the substance in the urine that originated from a calculable volume of blood. The GFR is typically recorded in units of volume per time

Formulas to calculate Glomerular Filtration Rate:

GFR for male :(140 - age) x wt(kg) / [72 x Serum Creatinine]
GFR for female :GFR(females) = GFR(males) x 0.85

There are several different techniques used to calculate or estimate the glomerular filtration rate (GFR or eGFR).FREE medical calculators online
