High platelet can be caused by many conditions. Generally, physiological normal people have a change of 6%-1% a day, which is lower in the morning, slightly higher in the afternoon, lower in spring and slightly higher in winter, higher in plateau area, higher after menstruation and higher after exercise. Pathological myeloproliferative diseases, primary thrombocytosis, acute hemolysis and acute suppurative infection, you should pay attention to them first, and then check them in turn later. If they are still high, you should find out how they are caused.

People's inflammatory reaction under the action of an inflammatory factor can lead to the increase of platelets, while other values are normal. The normal platelet content of people is 1-3 * 1 9/L, which is slightly higher than the normal value. If other values are normal and asymptomatic, there is generally no problem. Only platelets participate in blood coagulation, so higher values will increase the possibility of thrombosis.

Thrombocytosis: when > At 4x19/L, it is thrombocytosis, and primary thrombocytosis is common in myeloproliferative diseases, such as chronic myeloid leukemia, polycythemia vera, primary thrombocytosis, etc. Reactive thrombocytosis is common in patients with acute and chronic inflammation, iron deficiency anemia and cancer, and this increase is generally less than 5× 19/L. After treatment, the situation improves and the number of platelets will soon drop to normal level.
