A complete blood count (CBC) is a type of blood test that measures the different components of the blood, including red blood cells, white blood cells, and platelets. The CBC is a common laboratory test that provides important information about a person’s overall health and can help diagnose a variety of medical conditions. The CBC measures several different components of the blood, including:
- Red blood cells (RBCs): The CBC measures the number of RBCs in the blood, as well as the hemoglobin and hematocrit levels. These values provide important information about oxygen-carrying capacity of the blood and can help diagnose anemia and other blood disorders.
- White blood cells (WBCs): The CBC measures the number of WBCs in the blood, as well as the differential count of different types of WBCs. These values can help diagnose infections, inflammatory conditions, and other medical conditions.
- Platelets: The CBC measures the number of platelets in the blood. Platelets are important for blood clotting, and abnormalities in platelet counts can lead to bleeding disorders or thrombotic events.
The CBC is a useful screening test that can help diagnose a variety of medical conditions, including infections, anemia, leukemia, and other blood disorders. The test is often performed as part of a routine health check-up or as part of the evaluation of specific symptoms or medical conditions.
It is important to note that reference ranges for CBC results may vary depending on the laboratory and the individual’s age, gender, and other factors. Therefore, it is important to interpret test results in the context of the individual’s overall health status and medical history.
