Cystatin C (Serum (s))

Specimens:	1 ml Serum (s)
Method:	Nephelometry
Dimension:	mg/l
Set-up:	Mon Tue Wed Thu Fri Sat Sun
Duration:	1 day
Indication/Significance:	Renal function test with estimated glomerular filtration rate (eGFR) esp. in patients with unremarkable creatinin
Interpretation:	Elevated values indicate more… Elevated values indicate a restriction of the glomerular filtration rate. The determination of cystatin C has the following advantages over creatinine: The cystatin C concentration is largely independent of age, sex, weight and other non-renal factors. The concentration in the blood increases in accordance with the restriction of the glomerular filtration rate (GFR). Cystatin C is thus an ideal marker for the assessment of the GFR with a substantially higher specificity and sensitivity compared to creatinine, in particular with a low to moderate restriction of the GFR between 80 - 40 ml/min. Cystatin C therefore also detects a functional impairment of the kidney in the "creatinine-blind" area. close
