Creatinine

Creatinine is the standard marker of kidney filtration function.

Reference range

Adult reference: 0.6–1.3 mg/dL (sex- and muscle-mass-dependent). Functional optimization context only — not a diagnostic assertion. Range varies by lab, age, and sex.

Why it matters

Creatinine is influenced by muscle mass, hydration, and diet — not only kidney function. In members with substantial muscle mass it can sit above the standard reference without indicating renal pathology. REVRCEL panels report eGFR alongside it for a more interpretable read.

How REVRCEL clinicians read it

Always paired with eGFR. Muscle mass and hydration affect the value.
