Cystatin c clearance rechner
WebCystatin C is a non- glycosylated, basic protein ( isoelectric point at pH 9.3). The crystal structure of cystatin C is characterized by a short alpha helix and a long alpha helix which lies across a large antiparallel, five- stranded beta sheet. Like other type 2 cystatins, it has two disulfide bonds. WebBias was similar among the three equations, with a median difference between measured and estimated GFR of 3.9 ml per minute per 1.73 m 2 with the combined equation, as compared with 3.7 and 3.4 ...

WebInsights from Dr. Cockcroft: Calculating creatinine clearance was a "simple" resident research project designed by Dr. Henry Gault, my mentor at the time. We set out to evaluate the accuracy of a creatinine clearance nomogram by Siersbaek-Nielsen (1971). Our data, almost identical to that used to create the nomogram, resulted in our formula.
