WebSep 1, 2024 · To our knowledge, cystatin C has not been measured prior to this study in Jamaica. The two cystatin C based formulas were positive and fairly correlated with 24-h CrCl, CG, and MDRD and CKD-EPI cr equations. However, they mostly overestimates 24-h CrCl and could not accurately categorized the CKD patients in stage 1–5. WebCystatin C is made by all nucleated cells, not just muscle. As a result, cystatin C production varies less than creatinine production between individuals, and blood concentrations of cystatin C are fairly similar between individuals who have the same GFR. However, cystatin C has other potential confounders.
