How can you differentiate between vitamin B12 deficiency anemia and folate deficiency anemia given that they are both megaloblastic anemias?
Clinically, vitB12 deficiency will present with peripheral neuropathy and ataxia as well. A few clues can be picked on history e.g strict vegetarians have B12 deficiency and strict non vegs have folic acid deficiency Finally lab investigations help out e.g serum B12 levels and urinary levels of methylmalonic acid are elevated only in B12 deficiency
