Thank you foryour query,
The low ferritin, high RDW, low RBC and MCV are suggestive of iron deficiency
because of low iron stores in the body.
The most common cause of iron deficiency is low iron in the diet.
Iron should be given in the therapeutic range till for 1 month after the hemoglobin
normalizes to replenish the iron storage in the body along with vitamins like folic acid
, vitamin B12
, and vitamin C.
Hope I have answered your query.
