Platelets 59×10⁹/L, generally need to determine whether it is serious or not according to the specific condition, if it is caused by medication, it may recover after stopping the medication and is not particularly serious. If it is caused by aplastic anemia, leukemia, etc., it may be more serious. 1. Platelets 59×10⁹/L compared with the normal reference range of platelets (100~300)×10⁹/L, suggesting a significant reduction in platelets, can not be based on the platelet value to determine the severity of the general belief that it is not easy to cause spontaneous bleeding in the body, but if there is trauma and other factors that can easily lead to the occurrence of bleeding. If it is caused by drugs, platelets will also gradually recover after stopping drugs. It is not particularly serious at this time. 2. If it is caused by aplastic anemia, acute leukemia or other blood diseases, the situation is more serious, and it is necessary to treat the primary disease in time. For example, acute myeloid leukemia is treated with chemotherapy with drugs such as cytarabine. Platelets 59 × 10⁹ / L should be promptly to the regular hospital, by the doctor according to the symptoms, signs and auxiliary examination to determine the severity of the treatment under the guidance of the physician.
