Normal white blood cell count for newborns

White blood cells are a type of immune cells secreted by our body. Generally, when our body has a fever or inflammation, the most common finding in urine and blood tests is an increase in the number of white blood cells. This is because when there is some inflammation in the body, white blood cells increase in number to protect the body's functions from damage. The normal white blood cell count for a newborn is generally (15~20)×10^9/L.

1. Normal white blood cell values ​​for infants: The normal white blood cell value changes 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. Suggestions: The normal white blood cell count of a three-day-old newborn is about 15,000-20,000. The standard for children is less than 4.5x109/L for 10-14 years old, less than 5.0x 109/L for 5-9 years old, and less than 5.5x 109/L for those under 5 years old.

2. There are generally three common causes of leukocytopenia: one is medication, such as taking antipyretic analgesics, sulfonamides, etc. If the leukocytopenia is too obvious, you should stop taking the medication or change the medication; the second is viral infection, such as influenza, viral infection, etc. Now the child should increase the amount of water he drinks appropriately.

3.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.

4. Generally speaking, the normal white blood cell count for infants is 4.0-10.0. If it is higher than 10.0, it indicates a possible bacterial infection. The white blood cell count will also increase when drinking water, exercising, eating, and crying, but it is transient and will quickly return to normal after rest. If the white blood cell count is much higher than normal, fever symptoms may be present. Suggestions: The baby's current white blood cell count is 12.35, which is higher than normal, but not much higher than normal. If the baby has no other discomfort symptoms, you can temporarily not give treatment and just observe.
