Platelet counts higher than 300 × 10⁹/L with increased reactivity are dynamically observed for laboratory markers; medications (targeted drugs, interferon, etc.), stem cell transplantation, immunosuppressive therapy, etc. are given in primary cases.
The normal range of platelet count is (100 to 300) × 10⁹/L.
Platelets higher than 400 x 10⁹/L are considered thrombocytosis. The causes of thrombocytosis are reactive and primary increase. Reactive increase is seen after splenectomy, acute hemolysis, acute hemorrhage, acute infection and some cancer patients. Dynamic observation of laboratory indicators and active treatment of the cause.
Primary increase is seen in true erythrocytosis, chronic granulocytic leukemia, early stage of myelofibrosis, primary thrombocythemia, active drug therapy (targeted drugs, interferon, etc.), stem cell transplantation, immunosuppressant therapy, and so on.
When the platelet count is higher than 400×10⁹/L, it is necessary to go to the hematology department at the first time, and the doctor will conduct a systematic examination based on the clinical symptoms and past medical history, and make a definite diagnosis based on the results of the examination, and then carry out symptomatic and systematic treatment after the definite diagnosis.
