What is CBC ( Complete Blood Count) ?

The complete blood count (CBC) is a commonly ordered blood test that is used to provide information regarding a person’s overall health. It measures the number of red blood cells (RBC), white blood cells (WBC), platelets, and hemoglobin in the blood. It also measures the hematocrit, which is the ratio of red blood cells to the total volume of blood. Additionally, the CBC can measure other parameters such as the mean cell volume (MCV), mean cell hemoglobin (MCH), mean cell hemoglobin concentration (MCHC), and the red cell distribution width (RDW). The CBC is an important test because it can help to detect and diagnose many different types of medical conditions. For example, a high RBC count may indicate that a person is anemic, while a low RBC count may signify a lack of oxygen in the blood. A high WBC count may be indicative of an infection or inflammation, while a low WBC count could suggest a weakened immune system. A decreased platelet count could be a sign of a bleeding disorder, while an increased platelet count could indicate the presence of a clotting disorder. The CBC is typically ordered as part of a comprehensive physical exam or when a person is experiencing certain symptoms, such as fatigue, fever, or weight loss. It is also used to monitor the effects of certain treatments, such as chemotherapy or radiation therapy. Overall, the CBC is a valuable tool for healthcare professionals as it can provide important information about a person’s health and help to detect and diagnose a variety of medical conditions. It is important to note, however, that a CBC should be interpreted in conjunction with other clinical information in order to make an accurate diagnosis.
