The Metabolic Panel: 14 Numbers From One Blood Draw
If you’ve ever had blood drawn for a general checkup, there’s a good chance the Comprehensive Metabolic Panel (CMP) was part of it. It’s one of the most frequently ordered blood tests, because it covers so much ground in a single draw.
The CMP measures 14 things: glucose (blood sugar), calcium, sodium, potassium, and other electrolytes, along with markers of kidney function (BUN and creatinine) and liver function (ALT, AST, and more). It’s less a single test than a broad status report on several organ systems at once.
Why people order it
- A yearly checkup, even with no symptoms
- Establishing a baseline before starting a new medication or diet
- A doctor monitoring an existing condition
What to expect
Fast for 8 to 12 hours beforehand. Results are reviewed by a physician and typically appear in your portal within a few business days.
