Platelets 88 × 10⁹/L represents platelet drop, the risk level is low risk, generally speaking, no treatment is needed, to follow up and observe, to identify the cause of the disease. 1. Platelet 88×10⁹/L represents platelet drop, which is at low risk of platelet drop, and does not require treatment, but should be followed up and observed. 2. However, it is necessary to further identify the cause of platelet drop, to exclude some hematologic malignant diseases, such as leukemia, primary immune thrombocytopenia, etc., and it is necessary to target the cause of the disease, such as acute leukemia to be a cytarabine and other drugs such as chemotherapy, and primary immune thrombocytopenia to be treated with oral prednisone and other drugs. The normal value of platelets is (100~300)×10⁹/L, which is categorized into low-risk, intermediate-risk and high-risk according to the risk classification. Low-risk: platelet count at (50~100) x 10⁹/L; intermediate-risk: platelet count at (30~50) x 10⁹/L; and high-risk: platelet count less than 30 x 10⁹/L. Diagnosis and treatment of specific diseases should be under the supervision of a physician.
