WebCystatin C inversely correlates with the glomerular filtration rate (GFR), that is, elevated levels of cystatin C indicate decreased GFR. Cystatin C may provide more accurate assessment of GFR for very obese, older adults, or malnourished patients than creatinine. Cystatin C equation does not require patient ethnic data and can be used for ... WebNumerous studies have evaluated medication dosing based on either GFR estimate; vancomycin was the most frequently studied drug and its target level and elimination were better predicted by cystatin C. Overall, approaches to medication dosing and monitoring that include cystatin C concentrations have been shown to result in a better achievement ...

WebApr 14, 2024 · Cystatin C measurement is not generally available in Africa and, in addition, costs significantly more than measuring creatinine. Increasing the accessibility of cystatin C and driving the cost down seems the only practical method of overcoming this problem, although further research for other biomarkers is needed. WebCystatin C could be used in combination with creatinine as a confirmatory test for estimated GFR from creatinine. Summary: Cystatin C may have a role to estimate GFR in selected circumstances, and the next set of studies should be directed at developing implementation strategies for its use. bite block head and neck radiation
