A BMP (Basic Metabolic Panel) and a CMP (Comprehensive Metabolic Panel) are similar but not the same. Both panels include tests for electrolytes and kidney function. However, a BMP focuses on basic electrolytes (sodium, potassium, chloride, and bicarbonate) and glucose, while a CMP adds liver function tests (ALP, ALT, AST, and bilirubin) to the BMP. So, a CMP provides a more comprehensive view of your metabolic and organ functions. The choice between a BMP and CMP depends on your healthcare provider's specific diagnostic needs and the information they require.
