Ferritin: is slight low but your hemoglobin is good. consider iron supplementation and recheck level in 3 months

Ask your lab or MD: There is usually a within normal limits for the lab that you had them run by. You should go off of that. Also, a physician should discuss them with you and what to do about them if they are abnormal. Nothing is glaringly wrong if that helps.
