What is a Complete Blood Count (CBC) Test?
A Complete Blood Count (CBC) test gives a physician and their patient vital information regarding the kinds and numbers of cells in the patient's blood, particularly red and white blood cells, and platelets. This type of test helps a physician assess the cause of symptoms in a patient such as weakness, fatigue, or bruising, and can also help in determining if a patient may have anemia, an infection, or a number of other conditions or disorders.
Who May Need a Complete Blood Count (CBC) Test?
Patients who have experienced symptoms of fatigue, weakness, fever, bruising or unexplained weight loss will most benefit from a Complete Blood Count (CBC) test. It can also be useful in checking a patient for anemia, infections, determining how much blood has been lost in the case of bleeding, as well as diagnosing polycythemia and other diseases of the blood which include leukemia. This test is commonly part of a patient's yearly physical examination and can give crucial information into the general health of a patient.
What Should I Expect from My Complete Blood Count (CBC) Test?
Your Complete Blood Count (CBC) test is taken through a blood sample and can help a physician determine if there are any reasons for concern regarding your health, particularly in relation to the quality of your blood. It tests a patient for blood abnormalities which may cause malaise (fatigue) and bruising, as well as being useful in the diagnosis of anemia, infection, leukemia, and other blood-related disorders. Common reference ranges for results exist among CBC tests, though some labs may have different ranges for you and your physician.
