Measuring renal function: traditional methods and iohexol clearance
An accurate measure of glomerular filtration rate (GFR) is required in a variety of clinical situations. Plasma creatinine and creatinine-based equations have served as convenient estimates of GFR but they are subject to limitations. Formal assessment of GFR using clearance methods traditionally necessitates the use of radioactive traces such as 51Cr-EDTA. More recently, iohexol has […]
