The purpose of this study is to evaluate the utility of a blood volume monitor (BVM) in the management of renal anemia and its ability to avoid the variability of hematocrit (Hct) and hemoglobin values (Hb) depending on plasma volume through a simple method of monitoring the total hemoglobin mass (M<jats:sub>tHb<\/jats:sub>).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Predialysis blood samples for measurement were drawn at both the midweek treatment and the beginning\u2010of\u2010the\u2010dialysis\u2010week treatment in 30 patients.

There were significant differences between the Hb levels and between the hematocrit levels according to the time of dialysis. However, the M<jats:sub>tHb<\/jats:sub> remained constant.
