A Complete Blood Count (CBC) is a diagnostic test that measures the different components of blood, such as red blood cells, white blood cells, and platelets. It is a routine test that is often recommended by doctors to assess a patient's overall health or to diagnose or monitor various medical conditions.
During a CBC test, a small sample of blood is drawn from the patient's vein and sent to a laboratory for analysis. The test measures the total number of red blood cells, white blood cells, and platelets in the blood, as well as the levels of different types of white blood cells and hemoglobin.
A CBC test can help doctors diagnose and monitor various medical conditions, such as anemia, infections, leukemia, and bleeding disorders, among others. It can also be used to evaluate the effectiveness of treatment and to monitor the progression of certain diseases.
Overall, a CBC test is a simple and effective diagnostic tool that can provide important insights into a patient's overall health and help doctors make informed decisions about their care.
