Folic acid deficiency causes the production of large oval erythrocytes, hypersegmented polymorphonucleocytes, and pancytopenia. Vitamin B-12 deficiency causes subacute combined degeneration of the spinal cord with high cortical dysfunction. Before treatment is started with supplemental parenteral vitamin B-12 and oral folic acid, serum folate and vitamin B-12 levels must be measured.
