What is normal cystatin C level?
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 causes high cystatin C?
If you have an abnormally high concentration of cystatin C in your blood, it may mean you may have a kidney condition, such as chronic kidney disease. Higher levels of cystatin C may also be caused by diabetes, cancer, HIV, hyperthyroidism, or hypothyroidism.
What is difference between GFR and eGFR?
GFR is Glomerular Filtration Rate and it is a key indicator of renal function. eGFR is estimated GFR and is a mathematically derived entity based on a patient’s serum creatinine level, age, sex and race.
What is considered high cystatin C?
We categorized cystatin C into tertiles of low (≤1.230 mg/L), middle (1.231-1.710 mg/L), and high levels (>1.711 mg/L).
What is the normal range of eGFR?
A normal eGFR is 60 or more. If your eGFR is less than 60 for three months or more, your kidneys may not be working well.
How to measure cystatin C?
Kidney Function Can Be Assessed by Measuring Cystatin C in Blood. A new, international study from the Chronic Kidney Disease Prognosis Consortium found that use of blood levels of cystatin C to estimate kidney function – alone or in combination with creatinine – strengthens the association between kidney function and risks of death and end-stage renal disease.
What does cystatin C stand for?
What is the abbreviation for cystatin C? cystatin C is abbreviated as CC. (also CysC, CyC, Cys, Cyst C or CST-C)
How to calculate eGFR formula?
eGFR calculator. eGFR stands for estimated Glomerular Filtration Rate. eGFR is calculated from blood test results using a formula that looks at the level of creatinine (a waste product) in your blood. Results consistently below 60mL/min/1.73m2 indicate chronic kidney disease. eGFR can also be calculated by using the eGFR calculator below.
When is GFR cystatin C better used?
In clinical practice, the glomerular filtration rate (GFR) is often determined with serum creatinine. However, studies have shown cystatin C to be a better parameter for the diagnosis of impaired renal function. We compared GFR estimated by plasma cystatin C with GFR estimated by serum creatinine in a sample of 50 pediatric renal transplant recipients and 24 healthy children.
