Cystatin C

Cystatin C is a protein made by all cells in your body and filtered out by your kidneys. This test is a sensitive way to check how well your kidneys are working, sometimes even before other kidney tests show a problem. It’s especially useful if you have risk factors for kidney disease.

What's the difference between this and a standard lab blood test?

Same-day blood test results are processed in our clinic using advanced equipment, so you receive your results quickly and accurately—ideal for when you want fast answers or to monitor your health. The main difference with a standard blood test is that your sample is sent to an accredited external laboratory, and the results come back as a certified lab report. Both options are reliable and accurate; the key difference is that lab-processed results are officially certified, while same-day results are provided directly from our clinic.
