Clinical Information

The comprehensive metabolic panel measures 14 analytes and calculates an anion gap. It is used to assess kidney or liver status, electrolyte and acid/base balance, and blood glucose This comprehensive metabolic panel can also provide information about a patient's response to medications that would impact kidney or liver function.
