What causes high platelet count in young children?

Whether adults or children, the platelets in the blood change frequently. Even within a day, the platelets in the human body will change by 6% to 10%. This is common knowledge that everyone should know. For example, a person's platelet count will be lower in the morning, and for a period of time after lunch, the platelet count will be higher. The platelet count will also be lower in spring. These are all normal physiological phenomena. So what are the reasons that may cause high platelet counts in young children?

What causes high platelet count in young children?

The criteria for judging the results of routine blood tests for young children are different from those for adults: the white blood cell count is higher, and the white blood cell classification is mainly lymphocytes, so the proportion of lymphocytes will be higher, and relatively speaking, the proportion of neutrophils will be lower. This is a normal physiological phenomenon. It is only after the age of 7 that they gradually approach adult standards. The platelet count of 382 is slightly higher, but it does not exceed 400, so it is not thrombocythemia and can be considered normal. It is related to the child's vigorous bone marrow hematopoiesis. Domestic vaccines are just as effective and are free, so there is no need to worry.

It's okay, it just might cause some blood concentration. This domestic vaccine is also reliable.

Guidance:

It is possible to produce antibodies. You can use this with confidence. Not everything imported is better. Domestic products are also excellent.

1. First, review the blood routine test to rule out the influence of technical factors, because many cell fragments, crystalline substances, dust, blood clots, and even temperature and voltage can affect the platelet count. It is best to ask an expert in the laboratory to check the platelets manually.

2. If the platelet count is elevated upon reexamination, it may be thrombocythemia. 3. Thrombocythemia is a myeloproliferative disease of unknown cause. The main characteristics of this disease are high platelet counts in peripheral blood, accompanied by bleeding tendency, thrombosis, hepatosplenomegaly and granulocytosis. Its clinical characteristics are: ① More common in adults over 40 years old; ② Often accompanied by spontaneous skin and mucous membrane bleeding, repeated attacks; ③ Thrombosis; ④ Splenomegaly; ⑤ A significant increase in platelet persistence. 4. To confirm whether it is thrombocythemia, you need to go to the hematology department of a large hospital for acute bone marrow cytology examination and coagulation tests.
