Bone marrow aspiration is one of the most common tests performed in hematology. Through bone marrow aspiration, a clear diagnosis of various hematologic diseases can be made, as well as a judgment of the effectiveness of treatment for hematologic diseases. The cost of a bone marrow aspiration is around$200, which includes the cost of the puncture kit as well as the anesthesia and the procedure fee. The cost of bone marrow aspiration is not expensive, but the tests that need to be done after the bone marrow aspiration are often more expensive, such as doing immunological tests at the level of about$1000, cytogenetics at the level of about$600, and molecular biology tests that can vary significantly depending on the different items chosen for different diseases. Therefore, bone marrow aspiration itself is not expensive, but the various tests perfected to confirm the diagnosis of the disease are often more expensive, for example, for patients with acute leukemia, to make a definitive diagnosis, the general price is around 5,000 yuan.
