Overview
Methemoglobinemia can be diagnosed with several laboratory findings such as ABG analysis, co-oximetry and pulse oximetry.
Laboratory Findings
ABG Analysis
- On routine ABG analysis the partial pressure of oxygen (PO2) value should in normal reference ranges in patients with methemoglobinemia. The reason lies in the fact that the ABG value represents the oxygen content in the plasma, and not the oxygen-carrying capacity of hemoglobin.[1] [2] [3]
