WebAn 80-year-old man with type 2 diabetes and hypertension was referred to the nephrology clinic for persistent hyperkalemia. The patient was frail and sedentary, with a BMI of 37. His estimated glomerular filtration rate calculated using creatinine was 64 mL/min/1.73 m2. How would you interpret these... WebCystatin C is 13,000-D cysteine proteinase inhibitor produced by all nucleated cells at a constant rate. It is freely filtered at the glomerulus, and then, it undergoes catabolism within the kidney tubules, resulting in no urinary excretion. Thus, the serum level of cystatin C depends on GFR, and it can be used as a measure of kidney function ...

New Creatinine- and Cystatin C–Based Equations to Estimate GFR …

WebWhen evaluating a patient’s GFR, it is important to remember that eGFR is an estimate of the patient’s GFR. For eGFR cr and eGFR cys (calculated from cystatin C), 80-90% of values are within 30% of measured GFR. eGFR cr-cys (calculated using both creatinine and cystatin C) is more accurate than either eGFR cr or eGFR cys alone. WebSep 10, 2024 · Assessment of glomerular filtration rate (GFR) is fundamental to clinical practice, public health, and research.

WebUse. Since it is formed at a constant rate and freely filtered by the healthy kidney, cystatin C is a good marker of renal function. Serum concentrations of cystatin C are almost totally dependent on glomerular filtration rate (GFR). A reduction in GFR causes a rise in the concentration of cystatin C. 1,2. Can be used as a confirmatory test for ... 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.
