WebAug 10, 2016 · An arterial blood gas (ABG) is a test that measures the oxygen tension (PaO 2 ), carbon dioxide tension (PaCO 2 ), acidity (pH), oxyhemoglobin saturation (SaO 2 ), and bicarbonate (HCO 3) concentration in arterial blood. Some blood gas analyzers also measure the methemoglobin, carboxyhemoglobin, and hemoglobin levels. WebPotentially problematic scenarios that may arise in conjunction with CO analysis are a first analysis or a reanalysis requested months or years after the initial toxicology testing is completed; both raise the issue of the stability of carboxyhemoglobin in stored postmortem blood specimens.
