Answer

Indications for transfusion of PRBC are reviewed above. In general, hemoglobin concentration (typically reported in g/dL) is used to monitor RBC mass. This is a directly measured variable, whereas hematocrit is a calculated value when obtained from modern automated devices and, therefore, more prone to inaccuracy compared to direct measurement in a capillary tube spun on a centrifuge.
