Thanks for quiry. At Hb. Of 9.5 gm you don t need a blood transfusion.get repeat blood count done with peripheral blood smear examination to find that if any abnormal cells are present in it. For ruling out the cause of anemia you need detailed gen. Physical examination, thyroid examination and thyroid assay done. Some times there is problem in the digestive system which prevents your iron absorption in your body. Many more things need to be ruled out which a hematologist will do after examining you thoroughly an d having alook at your investigations. If other things are found in order last but not the least a bone marrow examination might be required. So I advise you to visit the hematologist who will decide what appropriate investigation you need.
