WebSep 23, 2024 · Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR. WebLarsson formula: eGFR = 77.24 × cystatin C−1.2623 The gold standard for measuring GFR viz. inulin clearance, urinary clearance of exogenous radioactive markers (125I-iothalamate and 99mTc-DTPA (diethylene-triamine -pentaacetate)), was not used in this study due to practical limitations.
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 … WebSerum 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. …
WebNov 4, 2024 · Background: Current equations for estimated glomerular filtration rate (eGFR) that use serum creatinine or cystatin C incorporate age, sex, and race to estimate measured GFR.
