The CMP is an expanded version of the basic metabolic panel (BMP), which does not include liver tests.

A CMP (or BMP) can be ordered as part of a routine physical examination, or may be used to monitor a patient with a chronic disease, such as diabetes mellitus or hypertension.

Calcium salts, lithium, thiazide diuretics, thyroxine, and vitamin D can all increase levels and may interfere with this test.

Tests of protein levels in the blood help screen for both kidney and liver disorders.

The National Institutes of Health provides ranges considered within normal limits, though optimal levels may vary by individual.
