You may feel pressure and pain as the marrow is being removed. (You may be given some numbing medicine, called anesthesia, before the procedure.)
Soreness at the site usually lasts from a few hours to 1-2 days.
Why the Test is Performed
You may have this test if you have an unexplained fever or if your health care provider thinks you have an infection of the bone marrow.
No growth of bacteria, viruses, or fungi in the culture is normal.
What Abnormal Results Mean
Abnormal results suggest that you have an infection of the bone marrow. The infection may be from bacteria, viruses, or fungi.
Fluid (aspirate) or a piece of tissue (biopsy specimen) from the bone marrow may be sent to the lab for many other kinds of tests. These tests can help gather information on immature blood cells such as:
How they look
How they are developing
What markers are present on the cell surface
How the chromosomes appear
