GFR can be accurately measured using radioactive substances, in particular chromium-51 and technetium-99m. These come close to the ideal properties of inulin (undergoing only glomerular filtration) but can be measured more practically with only a few urine or blood samples.

WebThe GFR (glomerular filtration rate) is a measure of how much blood (in millilitres) is ‘cleaned’ by the kidneys in one minute. By using a blood test to measure creatinine levels we can calculate the estimated GFR, known as eGFR. We do this using a formula that takes body size into account. The average adult body size is 1.73 m2.
