Bone marrow biopsy is a test that removes part of the patient’s bone marrow tissue through a bone marrow biopsy needle, and then stains it for pathological examination to make a diagnosis of blood system diseases. The cost of a bone marrow biopsy is around$300, and if you add the cost of a bone marrow puncture needle and anesthesia, it is around$500. Of course, the price will vary in different regions and different hospitals. Bone marrow biopsy is commonly used as an examination method for hematologic diseases, because some diseases cannot be diagnosed through conventional bone marrow aspiration methods or cannot be obtained intact, for example, in patients with aplastic anemia, due to bone marrow hematopoietic failure, the extraction of bone marrow is often unable to obtain a sufficient amount of bone marrow tissue, which can only be obtained by bone marrow biopsy. Similarly, in patients with myelofibrosis, due to the large amount of fibrous tissue proliferation in the bone marrow, dry aspiration often occurs during bone marrow aspiration, and this also requires a bone marrow biopsy to confirm the diagnosis.
