Complete blood count

Complete blood count (CBC), also known as full blood count, blood cell analysis, or blood picture, is a diagnostic method that reflects the number, morphology, ratio, and size of various blood cells (red blood cells, white blood cells, platelets) in the blood. It helps diagnose various conditions such as infections, anemia, leukemia, thrombocytopenia, and blood loss. Many patients with unknown causes can undergo a CBC for auxiliary diagnosis. Additionally, CBC is a common indicator for observing treatment efficacy, medication initiation or cessation, continuation or discontinuation of treatment, and disease recurrence or recovery. Indications CBC is a routine clinical laboratory test because it reflects the body's most basic condition and provides direction for clinical diagnosis and treatment, as well as monitoring the body's response to medication. Many patients visiting the hospital need to undergo this test, which is why it is called "routine." CBC is particularly necessary in the following situations: Suspected anemia Suspected blood loss Suspected infection Suspected hematological diseases, such as diseases related to abnormal blood cell morphology, abnormal bone marrow hematopoiesis, leukemia, and platelet morphology and functional abnormalities. Suspected other diseases affecting the hematopoietic system, such as connective tissue diseases, chronic kidney disease, hyperthyroidism, heart disease, and digestive system diseases. Before, during, and after using medications that may affect the hematopoietic system, such as chemotherapy drugs and immunosuppressants. Before invasive procedures, such as punctures and blocks. Before and after surgery Various other conditions that may affect the hematopoietic system.
