Method: The data of this study were from the National Health and Nutrition Examination Survey (NHANES) 1999-2002. A total of 4,832 older adults aged ≥60 who met the inclusion criteria were included.The CKD Epidemiology Collaboration (CKD-EPI) is a research group with interests in measurement and estimation of GFR (CKD-EPI GFR) and evaluation of surrogate endpoints for clinical trials in CKD (CKD-EPI CT). CKD-EPI was founded by Dr. Andrew S. Levey who served as Director from 2004 to 2018 and continues to serve as co-director.The accuracy of GFR equations that use cystatin C (eGFRcys) or creatinine-cystatin C (eGFRcr-cys) is not well studied in these populations. Study Design. A systematic review of original articles identified from PubMed and expert sources. Two reviewers screened articles independently and identified those meeting inclusion criteria.

Cystatin C is produced by all nucleated cells at a constant rate and the production rate in humans is remarkably constant over the entire lifetime. Elimination from the circulation is almost entirely via glomerular filtration. For this reason, the serum concentration of cystatin C is independent from muscle mass and gender in the age range 1 to ... Cystatin C is considered to be a preferred, unbiased marker to serum creatinine for estimating GFR and is independent of diet, protein intake, ethnicity, sex, physical activity and muscle mass. 2 GFR estimating equations that incorporate both creatinine and cystatin C values together are moreBackground: Precise monitoring of the glomerular filtration rate (GFR) is needed to estimate the allograft function in kidney transplant recipients (KTRs). The GFR is widely estimated with the use of formulas based on serum cystatin C (SCys) and serum creatinine (SCr) levels. We compared the efficacy of SCys-based equations with that of SCr-based …

Invert to mix with preservatives. Centrifuge and transfer the plasma to a labeled plastic transport tube (Note: The whole blood sample may be kept refrigerated at 4°C for as long as two hours before centrifugation, if necessary).The cystatin C equation increased C ‑statistics for death prediction (p < . vs. creatinine, p = . vs. combined equation). In conclusion, thisSerum creatinine and cystatin C are used to estimate glomerular filtration rate, but creatinine-based estimated glomerular filtration rate (eGFRcr), cystatin C–based estimated glomerular filtration rate (eGFRcys), and combined creatinine- and cystatin C–based estimated glomerular filtration rate (eGFRcr-cys) are often divergent, particularly in older adults. We investigated which estimated ... His estimated glomerular filtration rate (eGFR) was calculated using 3 equations that incorporated creatinine (eGFRcr), cystatin C (eGFRcys), and both creatinine and cystatin C (eGFRcr-cys), as shown in Table 2. An 80-year-old man with type 2 diabetes and hypertension was referred to the nephrology clinic for persistent hyperkalemia. Your Cystatin c level of 1.37 is a High Cystatin c level. High Cystatin c levels could indicate health issues. Typically, levels between 0.62 mg/L to 1.03 mg/L suggest no concerns. However, deviations from this range warrant prompt medical attention. Consulting a doctor for abnormal levels is advisable.
