A platelet count of 59 x 10^9/L is not serious if there are no obvious bleeding symptoms and is mild thrombocytopenia. 1. In clinical practice, platelet count below 100×10^9/L can be diagnosed as thrombocytopenia, when the platelet count is more than 50×10^9/L, generally speaking, there is no bleeding symptoms, you can follow up and observe in outpatient clinic, check blood routine regularly, avoid bumping in life, and temporarily do not take medication. 2. If the patient is a chemotherapy patient, review the blood routine 3 days after the end of chemotherapy, if the platelet count is lower than 75×10^9/L, it is necessary to monitor the blood routine, because the platelet has a long life span, and the response to the chemotherapy drugs will be pushed back to appear, and the thrombocytopenia will last for a period of time. 3. When the platelet count is lower than 50×10^9/L, it is recommended to give medication to elevate platelets, when it is lower than 20×10^9/L or there are obvious bleeding manifestations, consider platelet transfusion therapy. If there is any discomfort, consult a doctor in time for diagnosis and treatment under the guidance of specialized doctors.
