Laboratory

A) Testing in patients with severe symptoms should be directed toward evaluation of end organ ischemia (eg, arterial blood gases). No testing is required for patients with transient hypotension.
B) Blood methemoglobin concentrations should be measured in patients with clinical evidence of methemoglobinemia (eg, symptoms of hypoxia or skin discoloration). Asymptomatic exposures do not require methemoglobin determination.
C) Patients with clinically significant methemoglobinemia should be evaluated for hemolysis.
D) Patients with hemolysis should have testing for G6PD deficiency.
