Did you know that the complete blood count test is carried out by taking a few milliliters of blood sample directly from the patient? A complete blood count is a blood test used to evaluate your overall health. A complete blood count is a common blood test performed to monitor a medical condition and medical treatment. A complete blood count provides sufficient information about the number and type of cells in the blood, especially red blood cells, platelets, and white blood cells. A complete blood count helps your doctor check for symptoms, such as weakness, bruising, or fatigue. It also helps him diagnose conditions, such as anemia, which is a decrease in the amount of oxygen-carrying substance present in red blood cells, infections, and many other disorders. A complete blood count usually includes platelet count, white blood cell count, red blood cell count, hemoglobin, red blood cell indices, mean platelet volume, and white blood cell types. White blood cell count is an increase in fighting cells circulating in the blood. . The white blood cell count is also called leukocytosis. There are five main types of white blood cells: neutrophils, lymphocytes, eosinophils, monocytes, and basophils. The number of white blood cells varies from one medical practice to another. A count of more than 10,000 white blood cells in a microliter of blood in adults is generally considered a high white blood cell count. Abnormal test results are classified by numbers above or below 4,500 and 10,000 microliters. An elevated white blood cell count in children varies by age and size. The white blood cell count usually indicates a reaction to a drug that increases the production of white blood cells and a greater preparedness of the white blood cells to fight a… middle of paper… for information on hemoglobin content and size of the blood cells red. Abnormal values ​​indicate the presence of anemia and what type of anemia it is. Red blood cell indices measure the shape, size, and physical characteristics of red blood cells. There are three indices of red blood cells which are mean corpuscular hemoglobin concentration, mean corpuscular hemoglobin and mean corpuscular volume. Mean platelet volume is an automatically calculated measure of the average size of platelets in the blood and is generally included in the blood test as part of the complete blood count. Platelet volume is calculated in femtoliters which varies between 7.5 fL and 11.5 fL. The differential blood test measures the percentage of each type of white blood cell in the blood. It also reveals whether immature or abnormal cells are present.
