Cautions

pH: Contamination of sample with ambient air will falsely increase the pH.
iCa: Contamination of sample with ambient air will affect the sample pH, which will affect the portion of calcium bound to protein.
K: Potassium results are elevated with in vitro hemolysis. Hemolysis may be undetected in certain whole blood potassium measurements. Interpret results with caution.

Method Description

pO2, Glucose, Lactate: Amperometry

pH, pCO2, K, Na, ICA: Potentiometry

HCO3: Log (HCO₃ (c)) =   pH + log(pCO₂) – 7.608 mmol/L

HCT: 3.0 x tHb

COHGB, MTHGB, O2HGB, Total HGB, sO2: Oximetry

Base excess: HCO3- - 24.8 + 16.2 x (pH - 7.4)
