Platelets 36 x 10^9/L is thrombocytopenia, the severity of which is related to the specific etiology and cannot be generalized. Platelets 36 x 10^9/L below the normal reference range (100-300) x 10^9/L are considered thrombocytopenia, which can affect the body’s coagulation function and carry a risk of bleeding. Thrombocytopenia varies greatly in severity depending on the etiology. Some infections can cause thrombocytopenia, which can be relieved by fighting the infection. Thrombocytopenia caused by hypersplenism or splenomegaly can be restored by splenectomy. Autoimmune thrombocytopenia requires treatment with hormones and immunosuppressants. As for thrombocytopenia caused by blood diseases such as leukemia and aplastic anemia, the condition is more serious and requires chemotherapy and bone marrow transplantation. When the platelet is 36×10^9/L, it is recommended to consult a doctor in time to clarify the cause of the disease and standardize the treatment under the doctor’s guidance, so as not to delay the condition.
