When Kidney Tests Don’t Match: What Test Discrepancies Mean for Your Health
Understanding Kidney Tests: Creatinine and Beyond For decades, clinicians have relied on blood tests that measure creatinine to gauge kidney function. Creatinine is a waste product produced by muscles, and its level in the blood helps estimate how well the kidneys are filtering. The most common tool derived from this measurement is the estimated glomerular…

Kidney Test Discrepancies Signal Health Risks
Understanding the Test Discrepancy A growing body of research indicates that mismatches between two common kidney function tests could reveal greater health risks than either test alone. Traditionally, clinicians have relied on creatinine-based estimates of glomerular filtration rate (eGFR) to assess kidney health. A newer approach uses cystatin C, another biomarker, to calculate eGFR. When…
