What To Expect Before Bone Marrow Tests

Before having bone marrow tests, a doctor, nurse, or physician assistant will explain the testing process and procedure and answer questions you might have.

Let your health care team know:

  • Whether you're allergic to any medicines
  • Whether you have a bleeding disorder
  • What medicines you're taking (you might have to stop taking some medicines, such as blood-thinning medicines, before having bone marrow tests)
  • Whether you're pregnant

Before the tests, you may be given medicine to help you relax. This medicine makes you sleepy, so you likely won't be able to drive after the test. Thus, your health care team may advise you to arrange a ride home.
