Leukopenia depends on the degree of reduction, mildly does not need treatment, moderate or more to pay attention to the body, leukopenia resistance will be reduced easy to catch a cold and so on, serious if the need for drug treatment. If the leukopenia is caused by other diseases, we should further check the original disease, such as serious infection, after taking certain drugs, etc. Benign liver cysts do not need to worry if there is no obvious discomfort, and pay attention to the observation in the future. White blood cell count "WBC" 4000 ~ 10,000/ul White blood cells are responsible for eating and digesting the bacteria or foreign objects when they invade the body, this is the role of phagocytosis. When bacteria or foreign substances invade the body and cause an outbreak, the bone marrow hematopoietic stem cells produce many white blood cells and increase the number of white blood cells in the blood. Therefore, a disease can be diagnosed by checking the value of white blood cells in the blood, which is called a white blood cell count test. Normal Range The normal value of white blood cell count varies according to age; for newborn babies, the value is over 10,000; for toddlers under five years old it is 6,000 to 11,000, for children between 6 and 14 years old it is 6,000 to 10,000; and over 15 years old it is 4,000 to 10,000 as the normal value. The white blood cell count may also increase temporarily due to intense exercise or bathing, stress, etc., as well as after meals. Possible diseases in case of abnormality There are two reasons for an increase in white blood cell count: When bacteria that are harmful to the body invade the body. When the bone marrow grows abnormally due to leukemia. An increase in the white blood cell count is almost always due to infections caused by bacteria such as tonsillitis, pneumonia, cholecystitis, gastroenteritis, etc. However, when the white blood cell count reaches 20,000 or more, it may be a dangerous disease such as leukemia or sepsis, especially in chronic leukemia, where the count may reach 100,000 or more. A decrease in white blood cell count can be caused by a decrease in bone marrow function, an abnormally high level of spleen function, which destroys old white blood cells, or bone marrow dysfunction caused by the side effects of medication, so it is important to pay special attention to this. What should I do if there is an abnormality? If the white blood cell count is abnormal, it is necessary to repeat the test; if the result is 4,000 to 10,000 and there is no abnormality in other tests, there is no need to worry. In addition, if there is an increase in the number of white blood cells caused by acute inflammation such as tonsillitis, bronchitis, gastroenteritis, pyelonephritis, etc., the number of white blood cells will return to normal once the disease is cured. However, if there is a possibility of leukemia or sepsis, it is necessary to be hospitalized immediately and undergo a bone marrow examination. When the white blood cell count drops below 4,000, the body's defenses are lowered and the body is susceptible to infection by pathogens. If the white blood cell count is further reduced to less than 1,000, sepsis may develop if the patient is not immediately admitted to a sterile room, and a bone marrow examination will be conducted to diagnose the cause of the disease. In addition, the side effects of various medications can also reduce white blood cells and should be discontinued immediately if medications are being taken. Classification of White Blood Cells White blood cells increase in the blood after bacteria or foreign objects have invaded the body. If you look at white blood cells more closely, they can be categorized into five types: neutrophils, eosinophils, basophils, monocytes, and lymphocytes. These are not only different in shape, but also increase or decrease in proportion due to disease. To check the increase or decrease in the ratio of white blood cell types to diagnose a disease, this is called a white blood cell classification test. Possible Diseases Neutrophilic increase Tonsillitis, pneumonia, osteomyelitis, encephalitis, cholecystitis, acute gastroenteritis, leukemia, myocardial infarction, renal failure, etc. Eosinophilic increase Parasitosis, urticaria, allergy to medicines, bronchial asthma, allergic skin, etc. Lymphocyte increase Syphilis, tuberculosis, infectious subacute infections, whooping cough, goitre, etc. Mononuclear increase Chickenpox, measles, scarlet fever, etc. Neutropenia Septicemia, tuberculosis, severe pneumonia, enteric typhus, aplastic anemia, acute leukemia, etc. Lymphocytopenia Malignant lymphoma, tuberculous lymphadenitis, cancer, leukemia, etc.
