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 […]

Kidney Function Tests: eGFR, Creatinine, Cystatin C, uACR, and Urinalysis

How Blood and Urine Tests Assess Kidney Filtration, Kidney Damage, Electrolyte Balance, and Chronic Kidney Disease Risk

Kidney function tests are most useful when they are interpreted together rather than as isolated numbers. A blood Creatinine Test supports an estimated glomerular filtration rate (eGFR), Cystatin C with eGFR can add a second […]
