WebIntroduction. Assessment of glomerular filtration rate (GFR) is a crucial step in the evaluation of kidney function or failure. Ideally, GFR should be measured directly using substances that are freely filtered by the kidneys but neither secreted nor reabsorbed, such as inulin, iohexol or iothalamate.
