What diseases can be detected by a five-part complete blood count (CBC)?
The company arranged for a medical examination today, and I had the five-item blood test. I would like to know what diseases can be detected through this five-item blood test.
Doctor's answer (1)
The five-item complete blood count (CBC) primarily measures indicators such as white blood cell count, red blood cell count, hemoglobin, platelet count, and lymphocyte percentage in the blood. Details are as follows:
1. White blood cell count: An elevated white blood cell count is usually associated with infections, inflammation, or tissue damage; a decreased count may indicate diseases related to immune system disorders, post-radiation therapy, chemotherapy, or hypersplenism.
2. Red blood cell count and hemoglobin: These two indicators are usually evaluated together to detect anemia. Common conditions include iron-deficiency anemia and aplastic anemia.
3. Platelet count: An increased platelet count may be associated with hemorrhagic thrombocytosis, chronic inflammation, tumors, or myelodysplastic syndromes. A decreased count may indicate diseases such as aplastic anemia, acute leukemia, idiopathic thrombocytopenic purpura, or drug reactions.
4. Lymphocyte percentage: Lymphocytes are an important type of immune cell in the body. An increased percentage may suggest viral infections, certain types of leukemia, lymphoma, or related diseases.
The results of the five-item CBC serve only as an initial screening and are not definitive. Therefore, when abnormalities are detected, a comprehensive analysis combining patient symptoms and other diagnostic tests is necessary to accurately determine the underlying cause.
