A hematocrit is useful for detecting the proportion of red blood cells taken in the blood, which can reveal a deficit or excess of red blood cells, Healthline explains. A hematocrit is used to help diagnose a variety of conditions, including dehydration, leukemia, anemia and deficiencies in the patient’s diet. In addition to these conditions, the outcome of a hematocrit is influenced by pregnancy, having had a blood transfusion performed recently, or staying at a high-altitude location for prolonged periods. Less oxygen is available at higher altitudes, which increases hematocrit levels.
A complete blood count includes a number of tests and focuses in particular on assessing the count of a patient’s red and white blood cells and platelets, WebMD notes. Typically, a CBC also includes a test of mean platelet volume, hematocrit, various indices that provide information about the state of red blood cells, and a white blood cell differential. A CBC is useful for diagnosing a wide array of disorders, including infections and anemia.Learn more about Medical Ranges & Levels
