Cystatin C Blood Test
Monitor your kidney health at a deeper level with the Cystatin C Check Test , a highly sensitive diagnostic profile that measures serum cystatin C levels and estimates glomerular filtration rate (GFR) with greater accuracy than traditional creatinine-based tests. Because cystatin C is produced at a constant rate by all nucleated cells and filtered freely by the kidneys, this test offers valuable insight into kidney function even when other tests appear normal.
Why the Cystatin C Check Test Matters
Kidney filtration plays a crucial role in removing waste, balancing fluids and electrolytes, and supporting long term health. Traditional creatinine based measurements often give inaccurate results because muscle mass, age, or diet can influence them. A Cystatin C test avoids those issues because cystatin C levels remain steady and less affected by physical differences. This makes the test highly useful for older adults, bodybuilders, individuals with low muscle mass, or anyone who may show early signs of kidney impairment. When cystatin C levels rise, they can indicate reduced GFR and a higher risk of chronic kidney disease or cardiovascular complications.
What This Test Measures
-
Serum cystatin C concentration: The primary marker for kidney filtration efficiency.
-
Estimated GFR using cystatin C: A more reliable figure especially when creatinine results are unclear.
-
Optional add-on markers: Available combinations with creatinine, albumin–creatinine ratio or other renal biomarkers for enhanced evaluation.
Who Should Take This Cystatin C Test Test?
This test is ideal for:
-
Individuals with known or suspected kidney impairment where creatinine may be misleading.
-
Young or very muscular people or older adults where muscle mass skews traditional filtration estimates.
-
Anyone wanting an early, accurate measure of kidney function prior to symptoms.
-
People with hypertension, diabetes or cardiovascular risk who need close monitoring of kidney filtration.
