Cystatin C Test

Cystatin C is a protein that is produced by almost all the cells in your body. It is filtered out of the blood by the kidneys, and its levels in the blood can serve as a marker of how well your kidneys are functioning. Unlike creatinine, which is another marker used to assess kidney function, the levels of Cystatin C are not as affected by muscle mass. This makes it a more accurate indicator for patients with conditions that can alter muscle mass, such as the elderly, amputees, or those with muscle-wasting diseases.


  • Profile Name: Cystatin C Test
  • Sample Type: Blood
  • Preparations Required: No special preparation is required for this test.

The Cystatin C test measures the levels of Cystatin C in the blood. It is particularly useful for detecting early stages of kidney dysfunction, differentiating between chronic kidney disease and acute kidney injury, and evaluating kidney function in cases where creatinine measurement may be unreliable.

Frequently Asked Questions

Cystatin C test is a blood test that measures the levels of Cystatin C in the blood. It is used as an indicator of kidney function.

The test is performed to assess how well the kidneys are functioning, especially in situations where other markers like creatinine may not be reliable. It can also detect early stages of kidney dysfunction.

A blood sample is drawn from a vein in your arm. This sample is then analyzed in the lab to measure the level of Cystatin C.

Higher levels of Cystatin C in the blood can indicate that your kidneys are not functioning properly. However, certain medications and other factors can also affect Cystatin C levels.

In some cases, the Cystatin C test may be used instead of, or in conjunction with, a creatinine test to provide more accurate information about kidney function.

People who have risk factors for kidney disease or conditions that can alter muscle mass might benefit from a Cystatin C test. Your doctor will help determine if this test is right for you.

Certain medications, thyroid dysfunction, and inflammation can affect Cystatin C levels.

It is primarily used to assess kidney function, but research is ongoing into other potential applications.

You should consult a nephrologist, a doctor who specializes in kidney care, or speak with your primary care doctor.

There are minimal risks associated with the blood draw required for the Cystatin C test.

Managing underlying conditions, such as diabetes and high blood pressure, and living a kidney-healthy lifestyle can sometimes help to lower Cystatin C levels. It’s important to follow your doctor’s advice.

The frequency of testing depends on various factors including your health status and any underlying conditions. Your doctor will provide the best guidance on this.

For certain populations, such as the elderly or those with reduced muscle mass, Cystatin C can be a more accurate marker of kidney function compared to creatinine.

It's best to consult your doctor regarding any medications you are taking as some might affect the test results.

No, Cystatin C testing must be performed in a laboratory.

The Cystatin C test is a valuable tool in assessing kidney function, particularly in cases where other markers might be less reliable. Understanding your kidney function is crucial as kidneys perform essential roles in filtering waste products, regulating blood pressure, and ensuring the balance of minerals in the blood. If you are at risk for kidney disease, or if you have conditions that might make other tests like creatinine less reliable, ask your doctor about the Cystatin C test. It can provide crucial information to help manage your health.
