Creatinine — Severe

Creatinine 2.5 mg/dL: What It Means

Classification: Severe

Creatinine 2.5 mg/dL represents severe reduction in filtration (eGFR roughly 20-30) — CKD stage G4 territory. Urgent evaluation is needed.

About the Creatinine test

Creatinine is a waste product produced by muscle breakdown and filtered by the kidneys. It is the most common blood test for kidney function — a rising creatinine usually means falling filtration.

A standard blood test (part of the basic metabolic panel). No fasting required, but heavy exercise, creatine supplements, and a large meat meal the day before can raise it.

Reference: Reference ranges per major laboratories (Labcorp/Quest adult ranges); interpretation per KDIGO CKD guideline • Normal range: 0.7-1.3 mg/dL (adult; varies with muscle mass)
