Hematocrit. The hematocrit (Ht or HCT, British English spelling haematocrit), also known as packed cell volume (PCV) or erythrocyte volume fraction (EVF), is the volume percentage (%) of red blood cells in blood. It is normally 45% for men and 40% for women.ecause the purpose of red blood cells is to transfer oxygen from the lungs to body tissues, a blood sample's hematocritâthe red blood cell volume percentageâcan become a point of reference of its capability of delivering oxygen.
The classic symptoms of a bacterial infection are localized redness, heat, swelling and pain. One of the hallmarks of a bacterial infection is local pain, pain that is in a specific part of the body. For example, if a cut occurs and is infected with bacteria, pain occurs at the site of the infection.
