Laboratory Testing for Diabetes Diagnosis and Management. Test Summary. Cystatin C with Glomerular Filtration Rate, Estimated (eGFR) Test Details. Methodology. Particle …The incidence of CKD is projected to increase during the next 20 years because of increasing obesity rates and an aging U.S. population. 1. Early-stage CKD is often asymptomatic, making laboratory testing imperative for at-risk patients. This typically includes two tests, a serum creatinine with estimated glomerular filtration rate (eGFR), a ...Cystatin C–based eGFR (eGFR cys) testing offers an alternative for these groups. Although associations of elevated cystatin C levels with diabetes, obesity, and inflammation have been reported, 4,5 eGFR cys is less influenced by diet and muscle mass and is therefore more appropriate for patients in whom creatinine-based results may be misleading.

The cystatin C equation increased C ‑statistics for death prediction (p < . vs. creatinine, p = . vs. combined equation). In conclusion, this

The 2012 Kidney Disease Improving Global Outcomes (KDIGO) guidelines recommended using cystatin C to confirm the diagnosis of chronic kidney disease (CKD) determined by creatinine-based estimated glomerular filtration rate …In nonselective glomerular proteinuria, the urine electrophoretic pattern is often a nonspecific one which may be called “mirror image” to that of the serum. Contamination of the urine with blood can give a similar pattern. With selective glomerular permeability, albumin, α 1 -proteins, and transferrin are the predominant proteins ...Cystatin C has been around now for over a decade. It is not affected by tubular secretion, it is not affected by race, and it is a better marker of subsequent bad outcomes (see NephJC summary of study from Lees et al, Nat Med 2019). Right now it is more expensive, but the equations incorporating cystatin C seem to be the best of the lot.

Cystatin C is similar to creatinine in that it is produced at a constant rate and is freely filtered by the glomerulus. However, unlike creatinine, cystatin C is not solely produced in muscles and consequently, not linked to skeletal muscle mass. As a result, serum cystatin C correlates more closely to GFR than serum creatinine, especially in ...

Serum 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. Abstract. Purpose of review: The goal of this update is to raise awareness of clinical scenarios where cystatin C has clear and immediate benefits as an alternative glomerular filtration rate (GFR) biomarker to supplement creatinine. An additional goal is to focus the estimated GFR (eGFR) controversy onto medication prescribing for agents with ...
