Anemia is an important sign that often points to a serious and possibly treatable medical condition. Although defined as a reduction in red blood cell (RBC) mass, other readily available measures that estimate RBC mass, such as hemoglobin (Hb) concentration and hematocrit (Hct), are commonly used. In elderly persons (defined as those older than age 65 y for the purpose of this article), the etiology of anemia differs sufficiently from the etiology in younger adults to warrant considering anemia in elderly persons as a distinct entity. The limitation is that there was no control group as such since the sample size was small. A few patients were irregular not following the instruction given by the physician so assessment of drug action could not be controlled well. In some case a few necessary details were lacking and study conducted based on the available data. Other than Hb % no much extensive investigation procedure.
