# 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.
