If the count is too high (a condition called polycythemia), there's a chance that the red blood cells will clump together and block tiny blood vessels (capillaries). If the RBC count is low (anemia), the body may not be getting the oxygen it needs.
They also carry carbon dioxide back to the lungs so it can be exhaled. Red blood cells carry oxygen from the lungs to the rest of the body. Too many or too few of the different types of white blood cells can help find an infection, an allergic or toxic reaction to medicines or chemicals, and many conditions, such as leukemia. The numbers of each one of these types of white blood cells give important information about the immune system.
Each type of cell plays a different role in protecting the body. Immature neutrophils, called band neutrophils, are also part of this test. The major types of white blood cells are neutrophils, lymphocytes, monocytes, eosinophils, and basophils. White blood cell types (WBC differential). The number of white blood cells is sometimes used to find an infection or to see how the body is dealing with cancer treatment. When a person has a bacterial infection, the number of white cells rises very quickly. White blood cells are bigger than red blood cells but fewer in number. If an infection develops, white blood cells attack and destroy the bacteria, virus, or other organism causing it. White blood cells protect the body against infection. A CBC also helps him or her diagnose conditions, such as anemia, infection, and many other disorders.Ī CBC test usually includes: White blood cell (WBC, leukocyte) count. A CBC helps your doctor check any symptoms that you may have, such as weakness, fatigue, or bruising. ISBN 9780683307511.A complete blood count (CBC) gives important information about the kinds and numbers of cells in the blood, especially red blood cells, white blood cells, and platelets.

Sample for MPV testing is obtained in a Lavender-Top EDTA tube. In addition, low MPV may correlate with abnormally small platelet size, sometimes a symptom of a spectrum referred to as Wiskott–Aldrich syndrome (WAS), caused by a genetic mutation of the WAS gene. A high MPV is also a bad prognostic marker in patients with sepsis or septic shock. A low MPV may indicate inflammatory bowel disease (IBD), such as Crohn's disease and ulcerative colitis. Ībnormally low MPV values may correlate with thrombocytopenia when it is due to impaired production of megakaryocytes in the bone marrow, such as in aplastic anemia. It may also be related to pre-eclampsia and recovery from transient hypoplasia. This may be seen in immune thrombocytopenic purpura (ITP), myeloproliferative diseases and Bernard–Soulier syndrome. MPV may be higher when there is destruction of platelets. Īn increased mean platelet volume (MPV) increases the risk to suffer a heart disease Since the average platelet size is larger when the body is producing increased numbers of platelets, the MPV test results can be used to make inferences about platelet production in bone marrow or platelet destruction problems. Mean platelet volume ( MPV) is a machine-calculated measurement of the average size of platelets found in blood and is typically included in blood tests as part of the CBC. Can be used to make inferences about platelet production in bone marrow or platelet destruction problems
