eGFR by Cystatin C

The eGFR by Cystatin C test measures the estimated glomerular filtration rate (eGFR), which is an indicator of kidney function. Unlike the traditional eGFR test that relies on creatinine levels, this test uses cystatin C, a protein produced by cells throughout the body, to assess kidney function more accurately, especially in individuals with muscle mass abnormalities or those with extreme body weights. Abnormal levels of cystatin C can indicate kidney impairment, as the kidneys are responsible for filtering this protein from the blood. The eGFR value helps doctors determine the degree of kidney function and stage of chronic kidney disease (CKD). By integrating the information from the GFR With Cystatin C, this test provides a clearer picture of kidney health. It helps detect kidney problems earlier and allows doctors to make better decisions for managing and treating kidney conditions.
