A Basic Metabolic Panel (or BMP for short) is one of the most commonly performed medical tests.

It is a combination serum test for Sodium ion, Potassium ion, Chloride ion, Bicarbonate ion, Blood Urea Nitrogen, Creatinine, and Glucose.

The results are expressed (in order) by the diagram

Na |Cl  | BUN /
- - - - - - -  Glucose
K  |CO2 | Cr  \

Most physicians order it when they want more than one of the above values, and most laboratories offer it at a signficant discount over separate tests. Cynics say that this is because if more values are tested, more will be abnormal, and an abnormal result may require further testing.
