The eGFR is an index of how well the kidneys are functioning. This can be calculated using serum creatinine (eGFRcreat) or serum Cystatin C (eGFRcys). While an eGFRcreat sees more use due to its measurement in common lab screening tests like the Kidney Profile, there are individuals where an eGFRcys may be more reliable, such as in those with:1,2.Cystatin C (CysC), a cysteine protease inhibitor and low molecular weight protein, is an endogenous marker for glomerular filtration rate (GFR). Thus, the kidney function may be estimated based on CysC . It is produced by all human nucleated cells at a stable rate, as it is the product of a housekeeping gene . In ...Cystatin C testing on site allows a more rapid turnaround time and will facilitate using the eGFR cr-cys equation because the creatinine and cystatin C results will both be available to perform the calculation. When the cystatin C result comes from a referral laboratory, there are challenges to incorporate that value with a previously …Blood should be collected in a blue-top tube containing 3.2% buffered sodium citrate. 1 Evacuated collection tubes must be filled to completion to ensure a proper blood-to-anticoagulant ratio. 2,3 The sample should be mixed immediately by gentle inversion at least six times to ensure adequate mixing of the anticoagulant with the blood.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 ...After adjustment for GFR, cystatin C was 4.3% lower for every 20 years of age, 9.2% lower for female sex but only 1.9% lower in blacks. Diabetes was associated with 8.5% higher levels of cystatin C and 3.9% lower levels of creatinine. Higher C-reactive protein and white blood cell count and lower serum albumin were associated with higher levels ...Cystatin C (CYSC) analysis Assay. ...

You are older or have lots of muscle (such as a bodybuilder), where creatinine levels can vary. In these cases, a cystatin C test may give a ... Vitamin C is an essential cofactor for the conversion of dopamine to norepinephrine and in the metabolism of tyrosine and folate and the conversion of cholesterol to bile acids. In addition, vitamin C in the diet improves the absorption of non-heme iron, the form of iron present in plant-based foods. 9. LabCorp test: 121251 ( LabCorp ) Components: Cystatin C.

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. Abstract. Blood concentration of cystatin C is independent of muscle mass and tubular secretion. It can be used, in the absence of a reference method, as an alternative marker to creatinine for the evaluation of renal function and the estimation of glomerular filtration rate (GFR).
