Cystatin C Serum

• The Cystatin C Serum Test is a diagnostic blood test used to measure the level of cystatin C in the blood
• Cystatin C is a protein produced by all nucleated cells and is a marker of kidney function
• This Cystatin C Serum Test helps evaluate how well the kidneys are filtering blood and is considered an accurate measure of kidney health

• Cystatin C Serum Test assess kidney function and detect early kidney disease
• Cystatin C Serum Test monitors the progression of chronic kidney disease (CKD)
• Cystatin C Serum Test evaluate kidney function in patients where creatinine-based tests might be inaccurate, such as in older adults or those with muscle mass variations
• Cystatin C Serum Test predict cardiovascular disease risk in certain populations

• Collection of a blood sample from a vein in the arm
• Laboratory analysis to measure the concentration of cystatin C in the serum

• Normal Levels: Indicate healthy kidney function
• Elevated Levels: Suggest impaired kidney function or decreased glomerular filtration rate (GFR), which may indicate kidney disease

• Normal Results: Cystatin C levels are within the reference range, indicating normal kidney function
• Abnormal Results: Higher-than-normal cystatin C levels, suggesting potential kidney dysfunction or reduced GFR

Q. What is the Cystatin C Serum Test?
Cystatin C Serum Test is a blood test that measures the level of cystatin C, a protein that helps assess kidney function

Q. Why do I need a Cystatin C Serum Test?
Cystatin C Serum Test helps evaluate how well your kidneys are working and can detect early kidney disease

Q. How is the Cystatin C Serum Test performed?
A blood sample is taken from your arm and tested in a lab to measure the level of cystatin C

Q. Do I need to prepare for the Cystatin C Serum Test?
No special preparation is usually needed, but follow any instructions from your doctor

Q. What do normal Cystatin C levels mean?
Normal levels indicate that your kidneys are functioning well

Q. What do elevated Cystatin C levels mean?
Elevated levels suggest that your kidneys may not be filtering blood effectively, indicating potential kidney disease

Q. Is the Cystatin C Serum Test better than a creatinine test?
It can be more accurate in certain populations, such as older adults or those with varying muscle mass, making it a useful complement to creatinine tests
