[QUOTE="phoenix, post: 694487, member: 12578"] [USER=94045]@Bluetit1802[/USER] which one? The first one doesn't give the result as an egfr but like this Calculated creatinine clearance [B]132.97(ml/min[/B] (that's for a 40 year old male weighing 80kg) the second with the same parameters minus weight gives [B]GFR = 108 ml/min/1.73m2[/B]> 90 = Normal GFR The 90% confidence interval for this estimate is: 76-140 ml/min/1.73m2 Calculated for creatinine = 74, age = 40, sex = male, race = other So basically a slightly higher estimate but within the same confidence interval. Both would be considered fine.If you google it you find there is some controversy about which equation should be used when. Just double checked and both calculators have an input in micromoles/litre The second one also gives the caveat about local labs giving differing results If you have an eGFR value calculated by a local laboratory, use that. It is likely to be more accurate than this calculator, which cannot take into account local variations in creatinine measurements edit at 66kg the two calculators are about the same [/QUOTE]
