Cystatin C Test and its Function
The cystatin C test is a laboratory test used to measure the levels of cystatin C in the blood. Cystatin C is a protein produced by cells throughout the body, and its levels in the blood can be used as a marker of kidney function.
Conditions that may require Cystatin C Test
- Chronic Kidney Disease (CKD): The cystatin C test is used to diagnose and monitor the progression of CKD. Elevated levels of cystatin C indicate impaired kidney function and decreased GFR.
- Acute Kidney Injury (AKI): Cystatin C levels can rise rapidly in response to acute kidney injury, making it a useful marker for assessing kidney function in this condition.
- Drug Dosing: Cystatin C levels may be used to help determine appropriate drug dosing in certain medications that are cleared by the kidneys. Cystatin C-based equations can provide more accurate estimates of GFR for drug dosing adjustments.
Cystatin C Test Procedure
The Cystatin C Test is a simple blood test that can be performed in a laboratory. Before the test, the patient may be asked to avoid certain medications that may affect the results. During the test, our healthcare professional will use a needle to draw blood from a vein in the patient’s arm. The blood sample will then be sent to our laboratory for analysis.
Interpreting Cystatin C Test Results
Interpreting cystatin C test results involves comparing the measured levels of cystatin C with established reference ranges. Elevated levels indicate impaired kidney function and decreased GFR, while normal levels suggest normal kidney function. The results should be interpreted in the context of the individual’s clinical history, other kidney function tests, and overall health.
