What is a bone marrow aspiration and why is it done?
Platelets are produced in your bone marrow. This test is done to confirm that the platelet production process is working properly. The test is typically done at the hip bone. First a shot of novocaine or other numbing agent is given. Then a needle is pushed through the bone and into the marrow. Some of the marrow is then suctioned out and examined. While some people experience little or no pain, others find this test very painful.
