eGFR Creatinine-Cystatin C Calculation With Albumin:Creatinine Ratio, Urine

This test measures kidney function by combining blood levels of creatinine and cystatin C to calculate a filtration rate, while also checking the urine for albumin, a type of protein. It helps show how well your kidneys are filtering waste and whether there is physical damage causing protein leakage, which is important for monitoring kidney health. This combination of markers helps identify or rule out different stages of chronic kidney disease more accurately than standard tests alone. However, this test does not determine the specific cause of kidney damage or diagnose a condition without further medical evaluation.
