How is high white blood cell? Most people do not have a comprehensive understanding of human health indicators. Some people don't even know what high white blood cells mean. Everyone has a certain number of white blood cells, too high or too low is unhealthy. So what's with the high white blood cells?
How is high white blood cell? The normal range of 1 adult peripheral blood leucocyte number is (3.5-9.5 )×109/L. When the leucocyte number continuously exceeds 9.5× 109/L, it is considered to be higher than the normal value, which is called leukocytosis. Leukocyte is a general term for neutrophils, eosinophils, basophils, lymphocytes and other cells in blood. There are two main reasons for leukocytosis:
1. Pathological leukocytosis: Acute infections caused by various bacteria, such as pneumonia and appendicitis, serious tissue injuries, such as major surgery and myocardial infarction, leukemia and malignant tumors can all lead to neutropenia. Various viral infectious diseases, such as chicken pox and hepatitis, and the recovery period of some infectious diseases can lead to an increase in the number of lymphocytes in patients.
Some allergic diseases, such as bronchial asthma, urticaria and parasitic infectious diseases, are the reasons for the increase of eosinophils. In addition, if a large number of abnormal white blood cells appear, we should consider diseases such as malignant tumors of hematopoietic system, such as leukemia and myeloproliferative tumors.
2. Physiological leukocytosis: after strenuous exercise or childbirth, during pregnancy and childbirth, or in the case of severe cold and heat, some people may have a physiological reaction of neutropenia. In addition, in infancy, due to the development of the immune system, the number of lymphocytes in the body may be higher than normal.
It can be seen that there are many reasons for leukocytosis. When the laboratory examination shows that the number of white blood cells continues to be higher than the normal value, you should see a doctor in time, improve the systematic and regular examination and test, and treat it promptly and accurately after a clear diagnosis.
The reasons for the high white blood cells can be seen from the following aspects:
1, infection, bacterial virus infection may lead to an increase in white blood cell count. After active anti-infection treatment, the white blood cell count can be reduced to positive after the infection is controlled.
2. Hematological diseases, such as acute leukemia, chronic leukemia, myelodysplastic syndrome, polycythemia vera, primary thrombocytosis, etc., will lead to an increase in white blood cell count. In order to make a definite diagnosis, bone marrow puncture, flow cytometry and genetic testing are needed to make a definite diagnosis.
3. Some patients who have been treated with glucocorticoid for a long time, such as rheumatoid arthritis, systemic lupus erythematosus, Sjogren's syndrome and other connective tissue diseases, need to be treated with glucocorticoid for a long time. It can also cause high white blood cell count, and the white blood cell count can also be reduced to normal after reduction or withdrawal.
How is high white blood cell? 2 What is the high white blood cell? Because white blood cell examination is a very common blood routine index in clinical laboratory examination, which is on the high side and is generally common in physiological factors and pathological factors.
Physiological factors are running and strenuous exercise in daily life, which leads to a lot of sweating or emotional tension. At this time, excessive discharge of body fluids, water reduction and even dehydration will lead to blood concentration and natural increase of white blood cell concentration.
In addition, there are some pathological factors, such as inflammatory infection, including viruses, bacteria, mycoplasma and chlamydia invading the respiratory system, causing digestive system infection and enteritis. Taking away a lot of electrolytes and body fluids through diarrhea will also lead to the increase of white blood cells, which will accumulate in the urinary system, reproductive system and central nervous system, which will all lead to the increase of white blood cells.
Then there are rare blood diseases, such as leukemia, which will cause abnormal cancerous leukocytosis, make the white blood cell content in the blood too high, and finally accumulate in the hematopoietic system of individuals, leading to hemolysis, coagulation and even death.
Clinically, bilateral lung ct, skull ct and bone marrow can be taken to clarify these possible pathological conditions.
At the time of examination, the actual white blood cells are high, which is a sign of health problems. Under normal circumstances, the number of white blood cells in adult urine is about 4000 ~ 10000/μ L, and it is normal for infants to reach 15000 ~ 20000/μ L, while the number of white blood cells in children is11000 ~12000.
The phenomenon of high white blood cells in a person's urine mostly appears in patients with kidney disease, that is, their protein will be lost to the outside through urine. This is because the patient's renal basement membrane has been damaged and the filtration function of glomerulus has changed. For this disease, patients must be treated in time, otherwise there may be more uncomfortable symptoms and deeper damage to renal function.
In the physical examination project, each physical examination has its own significance, which can make everyone know more about their physical condition. The high white blood cells in urine deserve our attention. In order to avoid more serious consequences, friends with abnormal white blood cells must follow the doctor's advice and find the reason for active treatment.
How is high white blood cell? 3 What diseases can lead to high white blood cells in routine blood tests?
1, various cell infections
Cell infection can lead to abnormal increase of white blood cells in the body. The main function of leukocytes is to protect the body from other pathogens. If pathogens appear in patients, white blood cells will be destroyed at the first time, so the number will increase in a short time.
2. Inflammation
The increase of white blood cells caused by inflammation is the most common. This usually happens, so you need to see if you have any uncomfortable symptoms. If there is no obvious discomfort, the increase of white blood cells caused by inflammation will automatically decrease after a period of time. However, if there is obvious discomfort, then we should choose the appropriate drug treatment according to the specific situation.
3. Severe burns
Severe burns are very dangerous, because burns can lead to a large area of infection in the body, leading to a large increase in white blood cells in the body. In this case, it is necessary to consider the use of drugs for adjuvant therapy. Generally, drug allergy test can be carried out first, then antibiotics can be selected according to the results, and then the wound surface can be kept clean.
4. Blood diseases
Some blood diseases can also lead to high white blood cells in patients, such as leukemia and hemophilia. Therefore, patients with high white blood cells should not be careless. They should follow the doctor's advice, do further examination, make clear the cause, and then carry out targeted treatment to prevent the delay from getting worse.
