A BMP measures glucose, calcium, four electrolytes, and two kidney markers - the core chemistry snapshot. The CMP adds liver tests; fasting matters for the glucose line.

Common questions
What is a basic metabolic panel?
A basic metabolic panel is a standard blood test measuring eight substances that map your body's core chemistry, per MedlinePlus: glucose - the blood sugar snapshot; calcium - bones, nerves, and muscle function; sodium and potassium - the electrolytes nerves and heart rhythm depend on; chloride and bicarbonate - acid-base and fluid balance; and BUN plus creatinine - the kidney function pair. It is the routine panel in annual physicals, emergency rooms, and hospital admissions because it catches the common dangerous things fast: high or low glucose, kidney trouble, and electrolyte derangements. What it flags: high glucose points toward diabetes; abnormal creatinine and BUN flag kidney strain; low potassium causes weakness and palpitations; sodium out of range causes confusion and, when severe, seizures. Providers also use it to monitor medications - diuretics and blood pressure pills shift electrolytes, which is why follow-up draws get scheduled after starting them. The sibling test: a comprehensive metabolic panel adds liver enzymes and proteins to the same draw - if liver is in question, the CMP is the order. Fasting is typically requested for the BMP because of the glucose line. One abnormal value: hydration status and recent meals explain many mild flags, so a repeat is the usual first move before any worry. Pymander is a free AI doctor, 24/7 by text.
