What is the reason for the high white blood cell count in children's blood routine

When a child's white blood cell count is high in a routine blood test, parents will be very worried. Generally speaking, a child's high white blood cell count is mostly caused by a cold. Colds can cause fever, and the white blood cell count will naturally increase when you have a fever, so don't worry too much. At this time, you should drink more water, let your child get enough rest, and take medication under the guidance of a doctor.

Children's blood test: The most common disease for babies may be a cold. If it is not treated in time, the baby will develop a fever. At this time, if you take the baby to the hospital, the doctor will ask for a blood test first. Why do we need a blood test? Because when people are sick, the number of various cells in the blood changes. For example, when anemia occurs, the number of red blood cells or the hemoglobin content will change; when inflammation occurs in the body, the number of white blood cells will increase. Mainly look at which indicators There is often a long list of test items on the blood test report, but some are more professional items, for which we don't need to go into detail.

The first item on a routine blood test report is the red blood cell count. We know that the main function of red blood cells is to transport oxygen to various tissues and organs throughout the body and to expel carbon dioxide produced in the body. This main function is mainly achieved by a protein in red blood cells, which is hemoglobin (Hb). Under normal circumstances, the ratio of the number of red blood cells to the hemoglobin content is relatively fixed. However, in the case of anemia, the ratio between them will change. For example, in the case of hypochromic anemia, the decrease in hemoglobin content will be very obvious, and the ratio of red blood cells to hemoglobin will increase. Therefore, when looking at the test report, you must first pay attention to the values ​​of these two items.

White blood cells in the blood include neutrophils, eosinophils, alkaliphils, and lymphocytes. The white blood cell count (WBC) in the test report refers to the total number of white blood cells in the blood, while the differential count refers to the percentage of each type of white blood cell. Since various white blood cells have different physiological functions, the number of different types of white blood cells may change under different pathological conditions. Generally speaking, we only need to master the white blood cell count, neutrophil (N) and lymphocyte (L) classification, because in daily life, doctors judge whether the body has an infection based on the number of white blood cells, and then judge what type of infection it is and what type of medicine should be used based on the classification of white blood cells. Generally speaking, if the number of neutrophils increases, it means bacterial infection, and if the number of lymphocytes increases, it means viral infection. 3. Platelet count (PLT):

We all know that the main function of platelets is blood coagulation. Without them, we may bleed profusely from a small wound, or even be in danger of life.
