CompuNet Clinical Laboratories is pleased to announce the launch of Cystatin C with eGFR testing beginning July 14, 2025. Cystatin C is a biomarker that can be used as an alternative to creatinine to estimate kidney glomerular filtration rate (eGFR). It may serve as a more reliable marker of renal function in situations where previous kidney function tests have provided unclear results or in individuals with higher muscle mass. This test offers clinicians an additional tool for more accurate assessment of kidney function, helping support improved diagnosis and management decisions for patients with or at risk for kidney disease.
