Cystatin C Test: Early CKD Detection & Better eGFR

When a second filtration marker can clarify kidney function—and why it still needs clinical context.

A cystatin C test measures a blood protein that can be used to estimate glomerular filtration rate, or eGFR. It is generally less influenced by muscle mass than creatinine, making it useful when a creatinine-based […]

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

How paired kidney results, confirmation, and trends help clarify chronic kidney disease risk.

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 […]
