Sleep Apnea in Patients with MGUS and MM

The aspirate sample obtained for research at the time a standard-of-care biopsy is taking place will be approximately 40cc. Bone marrow aspiration removes bone marrow fluid and cells through a needle placed into the bone. Usually this sample is taken from the back of the pelvic bone, but it may also be taken from the sternum or the front of the pelvic bone. A bone marrow biopsy removes bone with the marrow inside and is done prior to the aspirate. Each biopsy and aspirate procedure takes approximately 15 minutes total. Bone marrow aspirate may be collected in a separate tube for research or collected from the standard-of-care specimen with left-over aspirate not otherwise needed for clinical purposes, or from previous procedures.
