A 25-year-old man is brought to the emergency department by ambulance after a motor vehicle accident. His car was rear-ended by a drunk driver while he was stopped at a traffic light. At the scene, he was noted to have multiple small lacerations over his upper extremities from broken glass. He has otherwise been healthy, does not smoke, and drinks 5 beers per night. He notes that he recently started trying out a vegan diet and moved to an apartment located in a historic neighborhood that was built in the 1870s. Physical exam reveals several small lacerations on his arms bilaterally but is otherwise unremarkable. A complete blood workup is sent and some of the notable findings are shown below:

Hemoglobin: 12.1 g/dL (normal: 13.5-17.5 g/dL)
Platelet count: 261,000/mm^3 (normal: 150,000-400,000/mm^3)
Mean corpuscular volume: 74 µm^3 (normal: 80-100 µm^3)

Further testing using serum hemoglobin electrophoresis reveals:
Hemoglobin A1 92% (normal 95-98%)
Hemoglobin A2: 6% (normal: 1.5-3.1%)
