A basic metabolic panel (BMP) (also urea and electrolytes or U&E, or urea, electrolytes, creatinine, or UEC or EUC in some countries) is a set of seven or eight blood chemical tests and is one of the most common lab tests ordered by health care providers. The BMP provides key information regarding fluid and electrolyte status, kidney function, blood sugar levels, and response to various medications and other medical therapies. It is frequently employed as a screening tool during a physical exam.
