Does white blood cell count of 35 to 40 indicate severe inflammation?

White blood cell count is a very common issue. When you go to the hospital for a checkup, you must check your red and white blood cells. Too many or too few white blood cells are abnormal. Some people's white blood cell count is 35 to 40. In this case, we need to make corresponding judgments and diagnoses based on the growth patterns and specific standards of white blood cells.

Main Features

White blood cells are a very popular topic, because when you go to the hospital for treatment, you often have to undergo laboratory tests, and the most common test is a routine blood test. The most common use of a routine blood test is the white blood cell count and classification. Therefore, it is necessary for the public to have a preliminary understanding of it and accumulate relevant basic knowledge.

White blood cells, commonly known as leukocytes, are a very important type of blood cells in human blood. White blood cells have many responsibilities in the human body. They have the functions of engulfing foreign matter and producing antibodies, healing the body's injuries and diseases, resisting the invasion of pathogens, and providing immune resistance to diseases. When a person is unwell, it is often manifested through significant changes in the number of white blood cells. Therefore, in many cases, a routine blood test is required when visiting a hospital. Nowadays, routine blood tests in hospitals are mostly done using instruments, often with more than 20 indicators. In many cases, doctors often first focus on whether the white blood cells (WBC) have changed. White blood cells are very special and important cells, so it is important to know something about them.

When talking about changes in white blood cells, the first thing to notice is the change in quantity. The total white blood cell count of a normal person is (4.0~10.0)×10^9/L. In fact, a value of 0.5×10^9/L above or below this value can be considered roughly normal, because it is related to people's individual differences. Adult men and women generally fall within this range, with not much difference between the genders, but children and infants are completely different. The white blood cell count of a newborn baby can reach (15~20)×10^9/L at birth, which can drop to around 15×10^9/L in the following week, and can reach (10~12)×10^9/L within 2 years old. Children under 5 years old are also often higher than the adult level, with an average value of around 8×10^9/L. As they grow older, it gradually approaches the adult level.

In fact, white blood cells can be further divided into five types. Counting these five types of cells separately using instruments or manual methods is called white blood cell differential counting. Among these five types of white blood cells, neutrophils account for 50%~70%, lymphocytes account for 20%~40%, monocytes account for 3%~8%, eosinophils account for 1%~5%, and alkaliphils account for no more than 1%.
