Shop - Cystatin C

Description

• Definition: Cystatin C is a protein produced by all nucleated cells in the body and serves as a biomarker for kidney function. It is filtered by the kidneys and its levels in the blood can indicate changes in glomerular filtration rate (GFR).
• Purpose: The Cystatin C test is primarily used to assess kidney function, especially in cases where serum creatinine measurements may be less accurate, such as in individuals with normal or low muscle mass, obesity, or in the elderly.
• Clinical Relevance: Cystatin C is considered a sensitive marker for detecting early renal impairment. It may provide more accurate estimates of kidney function compared to creatinine, particularly in populations at risk for kidney disease.
• Interpretation: Normal Cystatin C levels typically range from about 0.6 to 1.2 mg/L. Elevated levels suggest decreased kidney function and may indicate acute or chronic kidney disease. It can also be used to monitor disease progression and response to treatment.
• Testing Method: The Cystatin C test involves a simple blood draw, with the sample analyzed in a laboratory to determine Cystatin C concentration. Results are usually available within a day, offering timely insights into renal health.
