Complete Blood Count (CBC) test is a common blood test that is often ordered by healthcare providers to provide information about a patient’s overall health and to help diagnose a variety of conditions. The test measures the levels of different types of cells in the blood, including red blood cells, white blood cells, and platelets.
The CBC test provides important information about a person’s general health, as well as specific information about the following:
Red blood cells (RBCs): Measures the number, size, and shape of red blood cells. Abnormalities in these measurements can indicate conditions such as anemia or blood disorders.
White blood cells (WBCs): Measures the number of white blood cells, which are the body’s primary defense against infection. Abnormal levels of white blood cells can indicate infection or inflammation.
Platelets: Measures the number of platelets, which are important for blood clotting. Abnormal platelet levels can indicate a bleeding disorder or other health issues.
Hemoglobin and hematocrit: Measures the amount of hemoglobin (the protein that carries oxygen in red blood cells) and the proportion of red blood cells to total blood volume. Abnormal values can indicate anemia or other blood disorders.
The CBC test is a simple blood test that requires a small amount of blood sample. Results are usually available within a few hours. Healthcare providers use the results of the CBC test to help diagnose and monitor various conditions, such as infections, anemia, leukemia, and other blood disorders.
