Test includes:
pH, pCO2, pO2, Bicarbonate, Base Excess, Hematocrit, Hemoglobin, Oxyhemoglobin, Carboxyhemoglobin, Methemoglobin, Reduced Hgb, O2 content, Glucose, Calcium (ionized), Sodium, Potassium, Chloride, Anion Gap
Clinical significance:
The whole blood profile on a capillary specimen contains blood gas tests, electrolytes, H/H, glucose and ionized calcium. It combines to help diagnose perfusion (i.e. respiratory) abnormalities and metabolic abnormalities.
