What additional tests are included in the comprehensive metabolic panel (CMP) beyond the BMP?

The comprehensive metabolic panel (CMP) includes a broader range of tests compared to the basic metabolic panel (BMP). Specifically, in addition to the parameters measured in the BMP, the CMP also assesses liver function through a series of tests that evaluate various enzymes and substances associated with the liver. These hepatobiliary function tests are critical because they provide information on liver health, including how the liver processes and excretes substances.

The CMP typically includes tests for glucose, electrolytes, kidney function (such as creatinine and blood urea nitrogen), and various liver enzymes, bilirubin, and proteins. This combination allows for a more comprehensive assessment of a patient's metabolic and organ function compared to the BMP, which mainly focuses on renal function and electrolyte levels.

By including hepatobiliary function tests, the CMP enables healthcare providers to pinpoint issues related to liver health along with renal function and electrolyte balance, making it an essential tool in routine medical assessments.
