A "Blood Count" is a medical test that measures the number of different types of cells in the blood. It primarily assesses the levels of red blood cells, white blood cells, and platelets. This test helps doctors evaluate a person's overall health and detect various conditions, such as infections, anemia, and blood disorders. The results of a blood count are usually presented in a complete blood count (CBC) report. A CBC provides detailed information about the size, shape, and concentration of blood cells. This information is crucial for diagnosing diseases and monitoring the effectiveness of treatments, making it an essential tool in medicine.
