What the Cystatin C Test measures
Cystatin C is a small protein produced by almost all cells in the body at a steady rate and cleared by the kidneys. Because its production is less affected by muscle mass and diet than creatinine, it can give a more consistent estimate of kidney filtration in some people.
Why it's done
- Assessing kidney function, particularly when creatinine-based results may be unreliable
- Monitoring kidney function over time, on medical advice
- Providing additional context alongside other kidney tests
How to prepare
No fasting is needed — eat and drink normally. Wear something with sleeves that roll up easily, and keep a list of any medicines you take handy for your phlebotomist.
Understanding your result
Your report shows your cystatin C level with the reference range. A raised result suggests reduced kidney filtration and should be discussed with your doctor, who may use it to estimate your kidney function (eGFR).
Frequently asked questions
Do I need to fast for a cystatin C test?
No, this test does not require fasting.
How is cystatin C different from a creatinine test?
Both estimate kidney function, but cystatin C is less affected by muscle mass, so doctors sometimes prefer it or use both together for a clearer picture.
