Renal
Renal markers describe kidney filtration, nitrogen waste handling, urate excretion, and protein leakage. This topic brings together kidney-focused panels and related analytes that help characterize renal physiology and chronic kidney disease risk.
Frequently Asked Questions
What is most central in renal lab testing?
Creatinine and eGFR are the core filtration markers. BUN adds context on nitrogen waste handling, while urine albumin and related urine markers help assess kidney damage rather than filtration alone.
Why do renal markers often overlap with general chemistry panels?
Several kidney-related markers are also part of routine chemistry testing because renal function influences multiple aspects of internal balance. A kidney-focused topic brings those markers together in one place.
