The cost of bone marrow aspiration for high platelet count is about 500 yuan, but it varies from different regions, different hospitals and different follow-up examination programs. 1. Simple bone marrow aspiration includes the cost of bone marrow aspiration kit, the cost of anesthesia, and the cost of surgery, etc. While the bone marrow obtained from the aspiration needs to be sent for examination after the bone marrow aspiration, the examination items needed to be done for different diseases are not exactly the same, so the cost is also different. 2. Ordinary bone marrow aspiration only includes bone marrow smear examination, the cost is about 300~500 dollars. When the patient has a high platelet count, other tests may be added to the bone marrow aspiration, and the cost will increase with the number of tests. Bone marrow aspiration is an important test for checking hematologic diseases and is the gold standard for the diagnosis of many hematologic diseases such as various acute and chronic leukemias, multiple myeloma, aplastic anemia, myelodysplastic syndromes and other diseases. In addition to being used for diagnosis, it is of great significance for the exclusion of hematologic diseases, assessment of disease efficacy and prognosis. Therefore, it is recommended to consult the local hospital for the specific cost.
