Borderline low: All labs should be interpreted in a clinical context. Work up is usually initiated looking for possible sources for bleeding and include iron studies if no obvious cause for anemia is present. Make sure you have a discussion with your doc about what are your options going forward.

Need to address : Anemia in an adult male warrants exclusion of bleeding in the stomach and intestine. You ought to see a doctor for an evaluation so that the cause of anemia can be treated. Wish you good health!
