High platelet count in children

Platelets are an indispensable element in our blood. Their quantity in the human body exists within a certain range. If their quantity is too high or too low, it will bring many adverse effects to the human body and cause many diseases, such as leukemia, anemia, etc. Many children are more likely to have a high platelet count. What causes this?

High platelet count can be caused by many situations. For normal people, the platelet count generally fluctuates by 6%-10% a day. It is lower in the morning and slightly higher in the afternoon. It is lower in spring and slightly higher in winter. It is higher in plateau areas, increases after menstruation, and increases after exercise. For pathological myeloproliferative diseases, essential thrombocythemia, acute hemolysis, and acute suppurative infection, you should observe carefully first and then check again after a while. If the level is still high, you need to find out the cause. The inflammatory response of a person under the influence of certain inflammatory factors can lead to an increase in platelets, while other values ​​are normal.

The normal platelet count of a person is 100-300*10^9/L. If the platelet count is slightly higher than the normal value, there will generally be no problem if other values ​​are normal and there are no symptoms. It is just that platelets are involved in blood coagulation, so a higher value will increase the possibility of thrombosis. Thrombocytosis: When >400x109/L, it is thrombocytosis. Primary thrombocytosis is common in myeloproliferative diseases, such as chronic myeloid leukemia, polycythemia vera, essential thrombocythemia, etc. Reactive thrombocytosis is common in patients with acute and chronic inflammation, iron deficiency anemia and cancer.

This type of increase usually does not exceed 500×109/L. The situation will improve after treatment and the platelet count will quickly drop to normal levels.
