What causes high white blood cell count? Causes of high white blood cell count

Many children have fever during this stage. If the fever persists, you should check your blood routine in time. In many cases, you will find that the white blood cell count is high, which means there is inflammation in the body. The most common one is bacterial infection, and you need to treat it with anti-inflammatory treatment in time.

1. Children's blood routine 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 blood tests? Because when people are sick, the number of various cells in the blood will change. 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.

Second, when looking at the blood test report, we need to focus on three aspects:

Red blood cell count (RBC) and hemoglobin measurement (HGB)

The first item on a routine blood test 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 cell count (WBC) and differential count (DC)

: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.

Platelet count (PLT): We all know that the main function of platelets is blood coagulation. Without it, we may bleed profusely from a small wound, or even be in danger of life.
