Basic Metabolic Panel Information

A basic metabolic panel (BMP) is a set of seven or eight blood chemical tests. It is one of the most common lab tests ordered by health care providers. It provides key information that has a variety of applications in guiding the medical management of a patient. For example, values can be used to assess and monitor a patient's fluid and electrolyte status, kidney function, blood sugar levels, and response to various medications and other medical therapies. It is also frequently employed as a screening tool to look for problems that might need to be addressed, as many disease processes can cause a derangement in the blood serum levels of basic metabolites.

Components

The version with seven tests is often referred to by medical professionals in USA as the "CHEM-7", or "SMA-7" (Sequential Multiple Analysis-7).[1] The seven parts of a CHEM-7 are tests for:

Calcium (Ca2+) is often considered part of the BMP,[9][10] though, by definition, it is not part of the CHEM-7. A basic metabolic panel including calcium is sometimes colloquially referred to as a "CHEM-8".

Reporting

Pathophysiology sample values
BMP/ELECTROLYTES:
Na+ = 140 Cl− = 100 BUN = 20 /
Glu = 150
K+ = 4 CO2 = 22 PCr = 1.0 \
ARTERIAL BLOOD GAS:
HCO3- = 24 paCO2 = 40 paO2 = 95 pH = 7.40
ALVEOLAR GAS:
pACO2 = 36 pAO2 = 105 A-a g = 10
OTHER:
Ca = 9.5 Mg2+ = 2.0 PO4 = 1
CK = 55 BE = −0.36 AG = 16
SERUM OSMOLARITY/RENAL:
PMO = 300 PCO = 295 POG = 5 BUN:Cr = 20
URINALYSIS:
UNa+ = 80 UCl− = 100 UAG = 5 FENa = 0.95
UK+ = 25 USG = 1.01 UCr = 60 UO = 800
PROTEIN/GI/LIVER FUNCTION TESTS:
LDH = 100 TP = 7.6 AST = 25 TBIL = 0.7
ALP = 71 Alb = 4.0 ALT = 40 BC = 0.5
AST/ALT = 0.6 BU = 0.2
AF alb = 3.0 SAAG = 1.0 SOG = 60
CSF:
CSF alb = 30 CSF glu = 60 CSF/S alb = 7.5 CSF/S glu = 0.4

These lab values are often listed in a standard grid:

Na+ Cl− BUN
K+ CO2 creatinine

Glucose (and sometimes calcium, magnesium, and phosphorus) are listed to the right of this grid, but there is greater variation in how these values are reported.
