Kidney disease is silent until it's advanced, and the standard test is systematically wrong in muscular people. This panel measures function the way it should be measured in this population and adds the urine test that catches damage years before eGFR moves.
The 6 markers — and why each one is here
Not muscle-dependent — the only valid kidney read if you lift or take creatine
Creatinine, urea and electrolytes — the standard comparison
Anaemia is an early consequence of declining kidney function
Ordering the panel tells you your numbers. The protocol tells you what to do with them — why creatinine is a muscle-mass test that mislabels lifters and creatine users, the cystatin C result that settles it, and the high-protein myth the evidence doesn't support.

A normal cystatin C eGFR with a scary creatinine eGFR means you're muscular, not sick — that's the most common finding here in this community. Protein or blood in the urine needs a doctor regardless of eGFR. Raised uric acid points at metabolic problems and gout risk. A genuinely falling cystatin C eGFR across two draws is the finding that matters, and it needs a physician.
