Routine blood count: Routine blood count in children with high white blood cells

The most common disease of the baby may be a cold, once it is not timely, it will cause a fever, at this time take the baby to the hospital, and the doctor will let the blood test first. Why do I need a blood test? Because when a person is sick, the number of various cells in the blood changes.

For example, in anemia, the number of red blood cells or the amount of hemoglobin changes. When inflammation occurs in the body, the number of white blood cells increases. What indicators do you mainly look at There is often a long list of test items on the blood routine test sheet, but some are more professional items, and we don't have to delve into them.

Looking at the routine blood test sheet, we need to focus on three aspects:

Red blood cell count (RBC) and hemoglobin measurement (HGB): The first item of the blood routine test list is the red blood cell count test, we know that the main role of red blood cells is to deliver oxygen to various tissues and organs throughout the body, and excrete the carbon dioxide produced in the body, and to complete this main function mainly rely on a protein in red blood cells, which is hemoglobin (HB).

Under normal circumstances, the ratio of the number of red blood cells to the amount of hemoglobin is relatively fixed. However, in the case of anemia, the ratio between them changes, as in hypochromic anemia, the hemoglobin content decreases significantly, and the ratio of red blood cells to hemoglobin increases. Therefore, when looking at the test sheet, you must first pay attention to the values of these two items.

White blood cell count (WBC) and white blood cell differential (DC): White blood cells in the blood include neutrophils, eosinophils, basophils, and lymphocytes. The white blood cell count (WBC) on the lab sheet refers to the measurement of the total number of white blood cells in the blood, while the differential count refers to the percentage of various white blood cells.

Due to the different physiological functions of various white blood cells, the number of different types of white blood cells can change in different pathological situations. Generally speaking, we only need to grasp the white blood cell count, neutrophil (N) and lymphocyte (L) classification, because in ordinary life, doctors judge whether there is an infection in the body based on the number of white blood cells, and then judge what type of infection and what type of medicine should be used according to the white blood cell classification. In general, an increase in neutrophils is a bacterial infection, and an increase in lymphocytes is a viral infection.

Platelet count (PLT): We all know that the main function of platelets is blood clotting, and without it, we may bleed from a small wound and even become life-threatening.

Hello, I'm a medical student....High white blood cells, proves that children have inflammation, children's own diet is very unreasonable, they don't know what is nutritious, only the taste, it is recommended that parents guide, otherwise eating too much dry food is easy to cause inflammation.

When the number of white blood cells exceeds 10,000 cubic millimeters, it is called leukocytosis, which is common in pathological leukocytosis such as acute infection, severe burns, acute poisoning, malignant tumors, and leukemia.

Neonates, after strenuous exercise, etc., can sometimes cause temporary physiological leukocytosis. When the number of white blood cells is less than 4000 cubic millimeters, it is called leukopenia, which is more common in viral infections, such as influenza, viral hepatitis, malaria, aplastic anemia, drug poisoning, lead poisoning and X-ray injury.

White blood cells are important cells in the human body, and when they show uncomfortable symptoms, they often cause some physical diseases. Nowadays, many parents pay more attention to their children's physical health and often take their children for examinations. Some children have high white blood cells.

So what causes high white blood cells in children?

High leukocytes in children are likely to be caused by infection, especially bacterial infections, which may cause leukocytosis, and the severity of the infection may be related to the degree of leukocytosis. When children have high white blood cells, it is best to be checked in time and treated symptomatically**.

There are also some diseases that can cause increased white blood cells in children, and when children develop some blood diseases, for example, leukemia can also cause increased white blood cells. Children's physical health is particularly important and should be taken as soon as a blood disease occurs.

Some medications can also cause white blood cells to rise in children. In addition to these reasons, some children also have increased white blood cells after some strenuous exercise, which is normal and does not require special treatment. Parents should pay more attention to the child's state at ordinary times, and check it in time after experiencing uncomfortable symptoms**.

Can a blood routine detect leukemia in children?Leukemia can be detected in children with routine blood tests.

Because childhood leukemia is the most common malignant neoplastic disease in children, accounting for more than 90% of all childhood malignant tumors, and the vast majority of them are acute lymphoblastic leukemia.

After children suffer from leukemia, they often have a series of clinical manifestations such as anemia, infection, bleeding, superficial lymphadenopathy, and hepatosplenomegaly.

If you go to the hospital for a routine blood test, childhood lymphocytic leukemia will also have some characteristics of its own

First, the number of white blood cells will increase significantly, and the number of lymphocytes will increase significantly;

In addition, the patient's hemoglobin concentration and platelet count will also decrease significantly.

If the child has symptoms such as anemia, infection, bleeding, etc., and the blood test routine has the above characteristics, then in this case, acute lymphoblastic leukemia can basically be diagnosed, and of course, bone marrow aspiration is required for the final diagnosis.

What is the blood test like for leukemia?The blood routine examination of leukemia patients is the same as that of ordinary patients. Routine blood test is one of the most basic laboratory tests in the clinic, and it is the most general and basic blood test.

The general method of routine blood examination is to take peripheral blood tests, such as blood from the fingertips and earlobes. The collected blood is passed through the blood cell analysis instrument, and the results are reported by the computer, and the blood routine examination is basically completed.

What are the symptoms of early childhood leukemiaFirst of all, in the early stage of leukemia, the first symptom is anemia, which is mainly manifested as paleness, weakness, orange weakness, and excessive sweating. There is shortness of breath and rapid heartbeat. However, it is necessary to rule out anemia caused by other causes, such as anemia caused by blood loss such as hemorrhoids, gastrointestinal bleeding, and heavy menstrual bleeding, as well as nutritional deficiency anemia caused by picky eating.

Secondly, there will be irregular fever, and there will also be symptoms such as colds, beats, and coughs. Superficial lymph nodes may be enlarged for unknown cause**, and bleeding may occur frequently.

White blood cells are divided into 5 categories.

One is neutrophils (GRAN), which is normal, and the reason for the increase or decrease is the same as the white blood cell count; * Increase: bacterial infection, inflammation; Decreases: Viral infection

the second is lymphocytes (lymphocytes), which are normal and common in neutropenia, tuberculosis, whooping cough, etc.; Its decrease is common in neutrophilia; * Elevated: whooping cough, infectious mononucleosis, viral infections, acute infectious lymphocytosis, lymphocytic leukemia; Reduced: Immunodeficiency*

the third is eosinophils, which are normal and increased in parasitic diseases, allergic diseases and some ** diseases; *

Elevated: Chronic myeloid leukemia and chronic hemolytic anemia. *

the fourth is basophils, which are normal and 0, and have little clinical significance;

Fifth, monocytes, which are normal and increase in the convalescent period of acute infectious diseases. * Elevated: tuberculosis, typhoid, malaria, monocytic leukemia. *

e.Platelets (PLT): Normal: (100-300)%.

Elevated: Essential thrombocythemia, polycythemia vera, chronic leukemia, myelofibrosis, symptomatic thrombocythemia, infection, inflammation, malignancy, iron deficiency anemia, trauma, surgery, hemorrhage, splenic vein thrombosis after splenectomy, post-exercise.

Decreases: Primary thrombocytopenic purpura, disseminated lupus erythematosus, drug-allergic thrombocytopenia, disseminated intravascular coagulation, increased platelet destruction, decreased platelet production, aplastic anemia, bone marrow hematopoietic dysfunction, drug-induced bone marrow suppression, hypersplenism. *

f.erythrocyte sedimentation rate: Westergren method 0-15 mm hour for males and 0-20 mm hour for females; The iahinhkob method is 0-8 mm hours for males and 0-12 mm hours for females. *

Rapid growth: acute inflammation, connective tissue disease, severe anemia, malignant tumors, tuberculosis.

Slowing: Polycythemia, dehydration. g.

Reticulocyte count: normal: ( Elevated:

Hemolytic anemia, massive bleeding, iron deficiency anemia, pernicious anemia when vitamin B12 is used. Decreased: Bone marrow hematopoietic insufficiency, aplastic anemia, leukemia. *

Usually high white blood cells are accompanied by high neutrophils, and low white blood cells are accompanied by low neutral because white blood cells are usually more affected by neutrophils and sometimes lymphocytes If the white blood cells are high and neutral is low, then the lymphocytes must be elevated.

Leukocytes are a normal immune system of the body, when the body is invaded by bacteria, viruses and other foreign pathogens, it produces a self-protection mechanism of leukocyte elevation, and at the same time, in the process of using certain drugs (glucocorticoids, etc.) will also cause leukocytes and other cells to rise, so the simple elevation of leukocytes should exclude related factors, if the use is conventional antibacterial and related symptomatic treatment and the child's general condition is still high, According to my opinion, I should stop taking the drug, dynamically observe the blood picture, recheck it after a month, and ask the family to observe the child! Examination is always an examination, and it must be combined with clinical practice!

Physiologic leukocytosis is more common during strenuous exercise, after eating, during pregnancy, and in neonates. In addition, the number of white blood cells can also be different depending on the blood collection site, such as the average number of white blood cells in earlobe blood is higher than that in finger blood牐牪 硇园purple going?

Elevated is more common in acute purulent infection, uremia, leukemia, tissue damage, acute bleeding, etc. Combined with practical analysis.

For bacterial infection, sputum culture plus drug sensitivity, antibiotics are used.
