Laboratory Findings

First line investigations include the following:

• Examination of peripheral blood smear : Macrocytic anemia and hypersegmented neutrophils are classically seen in folate deficiency. Anisocytosis and poikilocytosis can also be observed.
• Complete Blood Count : Low hemoglobin, elevated MCV and MCH, thrombocytopenia, neutropenia.
• Reticulocyte count : Low corrected reticulocyte count which indicates decreased production by the bone marrow.

Reference Range
Folic Acid in Serum/Plasma Deficiency	3.6-15 mg/dl
Adequate Folic Acid Supply	> 4 ug/l
Erythrocyte Folic Acid	120-800 ug/l
