Chronic Kidney Disease: Why eGFR and Urine Albumin Must Be Read Together

How eGFR measures kidney filtration, UACR reveals kidney damage, and both results together strengthen CKD detection, classification, and risk assessment.

Chronic kidney disease testing uses two complementary measurements: an eGFR test, usually calculated first from serum creatinine, and a urine albumin test, most often reported as the urine albumin-to-creatinine ratio (UACR). The eGFR test estimates […]

Cystatin C Test: Early CKD Detection & Better eGFR

A practical guide to cystatin C testing for early CKD detection—what it is, why it outperforms creatinine in many cases, how combined eGFR (creatinine + cystatin C) sharpens staging, and which labs to order through Ulta Lab Tests and Quest Diagnostics.

Cystatin C kidney function testing is rapidly becoming the gold standard for early detection of chronic kidney disease (CKD), providing a muscle‑independent, highly sensitive measure of glomerular filtration that often outperforms creatinine and BUN. In this in‑depth guide, […]
