What is the normal range of white blood cell count for infants?

In fact, the human body's white blood cell count has a normal value. If it is not within the normal range, it means that the body has been harmed by some adverse effects. If we fail to pay attention to treatment, it may also pose a threat to our lives and health. Therefore, everyone must understand the normal range of white blood cell counts. The following is an introduction to the normal value of infant white blood cells.

White blood cells were formerly known as leukocytes. It is an indispensable cell that makes up the blood. It is widely present in tissues other than blood vessels and lymphatic vessels as well as in blood and lymph. Abnormal white blood cells in infants can cause dangerous diseases such as leukemia, which directly threatens the baby's life. If mothers know the normal white blood cell values ​​of their babies, they can scientifically help their babies detect white blood cell abnormalities in a timely manner, thereby preventing the occurrence of dangerous diseases.

Normal white blood cell values ​​for infants: Normal white blood cell values ​​change with age, and the younger the age, the higher the value. The average is less than 20,000 within one month, about 11,000 within one year old, and decreases year by year after 2 years old, approaching adults at around 10 years old. Specifically, the normal white blood cell value for children is (5-12)×109/L; for newborns it is (15-20)×109/L.

Symptoms and causes of abnormal white blood cells in infants:

1. Leukocytosis in children: The most common is granulocytosis, which is mainly caused by bacterial infection, followed by fungal (also known as mold), viral, protozoan, rickettsial and other infections. Non-suppurative inflammatory diseases (such as rheumatoid arthritis and other collagen diseases), poisoning, bleeding, hemolysis and other diseases that cause bone marrow hyperplasia are also often accompanied by granulocytosis. In addition, physical and mental factors such as exercise, pain, panic, and rage can also cause granulocytosis. An increase in white blood cell count in children is mainly seen in five situations: leukemia, leukemoid reaction, extramedullary hematopoiesis caused by various reasons, infectious mononucleosis or infectious lymphocytosis, and severe bacterial infection.

2. Increased eosinophilia in children: The main cause is parasitic disease, followed by allergic diseases. Allergic pneumonia caused by the migration of hookworms, filarial worms, schistosomes and ascaris larvae can all cause an extreme increase in eosinophils, which can account for more than 80% of the total white blood cell count. Measles, eczema, angioedema, asthma, and scarlet fever are also common causes of eosinophilia.

3. Lymphocytosis in children: mainly seen in whooping cough, tuberculosis, infectious lymphocytosis, infectious mononucleosis, and lymphocytic leukemia.

It is hoped that through the above introduction, parents will have a scientific understanding of the common sense issues about the normal white blood cell count of infants. This is also to better help ensure the health of infants, because for infants, any disease in their bodies will cause greater and greater harm.
