A metabolic panel is a group of blood tests that check your blood sugar, kidney function, and salts (electrolytes) — and, in the comprehensive version, your liver and proteins too. It gives a broad snapshot of body chemistry.
| Measure | Range |
|---|---|
| Glucose | 70–99 mg/dL (fasting) |
| Sodium | 135–145 mmol/L |
| Potassium | 3.5–5.1 mmol/L |
| Creatinine | 0.6–1.3 mg/dL |
| Blood urea (BUN) | 7–20 mg/dL |
A basic metabolic panel (BMP) checks sugar, kidney function and electrolytes. A comprehensive one (CMP) adds liver tests and proteins. Your doctor chooses based on what they need to know.
Often yes, mainly for an accurate glucose reading. Your lab will tell you whether an 8–12 hour fast is needed.
It screens for diabetes, kidney problems, salt imbalances and (in the comprehensive version) liver problems — a broad first-line health check.
