Lab Values: BMP and CBC

BMP: Sodium (Na+); why should you care?

135-145 mEq/L; water balance/tonicity

BMP: Potassium (K+); why should you care?

3.5-5.0 mEq/L; cardiac and neuromuscular excitability --> too high or too low you die

BMP: Chloride (Cl-); why should you care?

96-106 mEq/L; tracks sodium and acid-base changes

BMP: Bicarbonate / Total Carbon Dioxide (CO2); why should you care?

24-30 mEq/L; metabolic acid-base status

BMP: Blood Urea Nitrogen (BUN); why should you care?

8-20 mg/dL; volume status, renal perfusion, protein catabolism

BMP: Creatinine (SCr); why should you care?

0.6-1.2 mg/dL; kidney function / excretion

BMP: Glucose; why should you care?

65-100 mg/dL; hyperglycemia can shift water and affect sodium

BMP: Calcium (Ca2+); why should you care?

8.5-10.2 mg/dL; neuromuscular and cardiac function

CBC: White Blood Cells (WBCs)

4.4-11.0e-3 cells/L

CBC: Red Blood Cells (RBCs)

Males: 4.5-5.9e-6 cells/uL

Females: 4.1-5.1e-6 cells/uL

CBC: Hemoglobin (Hgb)

Males: 14-17.5 g/dL

Females: 12.3-15.3 g/dL

CBC: Hematocrit (Hct)

Males: 42%-50%

Females: 36%-45%

CBC: Platelet Count (Plt)

150,000-450,000 cells/uL

Phosphate - not part of standard panel, need to order separately; why should you care?

3.0-4.5 mg/dL; ATP, cells, bones, membrane functions
