What is cystatin C with eGFR?

Cystatin C with Glomerular Filtration Rate, Estimated (eGFR) – Cystatin C is a non-glycosylated, low molecular weight (13,250 kD) cysteine proteinase inhibitor that is produced by all nucleated cells and found in body fluids, including serum.

How is cystatin C clearance calculated?

(iv) GFR calculated according to CKD-EPI creatinine and cystatin formula: 177.6 × ( serum creatinine ( mg dL ) ) − 0.65 × ( serum cystatin C ( mg L ) ) − 0.57 × age − 0.2 . The correction factor of 0.82 was used for women.

What is considered high cystatin C?

The normal range of cystatin C is around 0.62 – 1.15 mg/L. Values can vary between laboratories. Generally, higher cystatin C levels point to poor kidney function [7].

What is a good cystatin C level?

Normal serum creatinine values range from 0.6 to 1.3 mg/dl, and normal serum cystatin C values range from 0.6 to 1 mg/l.

What does cystatin C stand for?

Cystatin C (CysC) is a cysteine protease inhibitor that is present in all tissue and produced at a constant rate, filtered freely, and neither secreted into the renal tubules or absorbed into the blood stream from the renal tubules. From: Biomarkers in Cardiovascular Disease, 2019

What is cystatin C level?

The healthy range for Cystatin C is 0.57 – 1.05 mg/l. The Randox assay can comfortably detect levels outside of the healthy range measuring between 0.4 – 10 mg/l.

What does GFR tell you?

Glomerular filtration rate (GFR) is a test used to check the functioning levels of the kidneys. Specifically, it estimates how much blood passes through the glomeruli (tiny filters) in the kidneys. GFR also tells you how much kidney function you have.

What does GFR stand for?

GFR stands for glomerular (glow-MAIR-you-lure) filtration rate. A blood test checks your GFR, which tells how well your kidneys are filtering. It’s important to know your GFR if you are at risk for kidney disease. A urine test will also be used to check your kidneys.
