My iron serum (sideremia) it s lower than normal (39 to 50/170 ug/dl). I have to worrying? Hemoglobin and red blood cells are ok. Thank you. Kr

If the Hemoglobin is. Normal hemoglobin, then there is nothing to worry about. Serum iron value is only meaningful if thee is presence of anemia(low hemoglobin). Otherwise there is no reason to check serum iron level..
