Conclusion: Cystatin C-based eGFR equations are better than creatinine-based eGFR equations in predicting the clearance of vancomycin. This suggests that utilising cystatin C-based eGFR equations could result in better accuracy and precision to predict vancomycin pharmacokinetic parameters. can a ultrasound detect kidney stones

"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. " - Cystatin c clearance rechner

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.
