Clinical Notes

Although included in the Complete Blood Count, hemoglobin (Hb) and hematocrit (Hct) are routinely ordered independently and together by healthcare providers to assess oxygen-carrying capacity. Hemoglobin is the major component of the red cell and functions to transport oxygen. It also acts to buffer carbon dioxide formed during metabolic activity. Hematocrit or packed red cell volume (PCV) is the percent of red cells contained in whole blood.
