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.
Symptoms of bacterial meningitis usually appear suddenly. Symptoms of viral meningitis may appear suddenly or develop gradually over a period of days. For example, the symptoms of viral meningitis after mumps may take several days or weeks to develop. The most common symptoms of either form of meningitis include: Fever. Severe and persistent headache. Stiff and painful neck, especially when trying to touch the chin to the chest. Vomiting. Confusion and decreased level of consciousness. Seizures. Less common symptoms include: Sluggishness, muscle aches and weakness, and strange feelings (such as tingling) or weakness throughout the body. Eye sensitivity and eye pain from bright lights. Skin rash. Dizzy spells. Babies, young children, older adults, and people with other medical conditions may not have the usual symptoms of meningitis.
