Basic metabolic panel

A basic metabolic panel (BMP) is a set of seven or eight blood chemical tests.

[edit] Components

The version with seven tests is also known as "CHEM-7".^[1] The seven parts of a CHEM-7 include tests for:

Four electrolytes:
- sodium (Na⁺) ^[2]
- potassium (K⁺) ^[3]
- chloride (Cl⁻) ^[4]
- bicarbonate (HCO₃⁻) or CO₂ ^[5]

Calcium (Ca²⁺) is often considered part of the BMP,^[9]^[10] though, by definition, it is not part of the CHEM-7.

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	p_aCO₂=40	p_aO₂=95	pH=7.40
ALVEOLAR GAS:
	p_ACO₂=36	p_AO₂=105	A-a g=10
OTHER:
Ca=9.5	PO₄=1	Mg²⁺=2.0
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) are listed to the right of this grid, but there is greater variation in how these values are reported.
