The probable explanation for the simultaneous increase of creatinine ratios in patients with eGFRcystatin C < 60% of eGFRcreatinine is that their elimination by the kidneys is decreased. GFR is used to assess the kidney filtering capacity and renal function. Normal kidney filtering capacity ...
Reportable range: 0.25 mg/L-7.00 mg/L The eGFR is calculated using cystatin C measurements calibrated to International Federation of Clinical Chemistry (IFCC) certified reference material, along with the patient's age and sex, according to the Chronic Kidney Disease Epid...
Results Among 965 researchers excluded outliers, male creatinine was (72.68±9.53) μ Mol/L, female creatinine was (56.19±7.56) μ Mol/L, Cystatin C was (0.90±0.13) mg/L, EGFR was non normal distribution. Comparing EGFR formulas of different estimates, it was found that dispersion of ...
While most commonly used, creatinine is not the only substance that can be used to estimate GFR. For example, some eGFR tests measurecystatin C,a protein made by most types of cells in the body. Unlike creatinine, the blood level of cystatin C is less influenced by differences in our body...
The limitations of estimating GFR from creatinine and/or cystatin C include low sensitivity in detecting early CKD and poor prediction of the course of CKD. These limitations have been described previously in detail31,32,33. However, despite these limitations, eGFR is the outcome most often used...
Population Reference Ranges are usually established by measuring an analyte in a large population of apparently healthy individuals and consider the central 95% as within the reference range or normal. For example, the central 95% for K+ is 3.5 to 5.0 mEQ/L (3.5 to 5.0 mmol/L). Likewise,...

Estimates of the prevalence of eGFR <60[absent HT, DM, high ACR] did not differ substantially by measure in Peru, and were lower in Malawi and England when using cystatin C. Similar patterns were seen for eGFR <60[no exclusions] (Table 3 and Supplementary Table S5). Table 3. Age-...
Creatinine serum level augmentation of as little as 0.3 mg/dL could correspond to a great decrease in GFR, so that creatinine serum levels in the normal range or with minor changes could mask sever GFR alteration. Consequently, measuring and reporting both eGFR and creatinine serum level ...
