Alternative Names Return to topCulture - bone marrow
Definition Return to top
Bone marrow culture is an examination of the soft, fatty tissue found inside certain bones. This tissue, called bone marrow, produces blood cells. The test is done to find out if there is an infection inside the bone marrow.
How the Test is Performed Return to top
The doctor removes a sample of your bone marrow from the back of your pelvic bone or breast bone. This may be done using bone marrow aspiration or a biopsy.
The removed tissue is sent to a lab. It is placed into a special container called a culture dish. Every day, the laboratory specialist will look at the tissue under a microscope to see if any bacteria, fungi, or viruses have grown.
If any bacteria, fungi, or viruses are found, other tests may be done to learn which drugs will kill the organisms. Treatment can then be started based on these results.
How the Test Will Feel Return to top
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 Return to top
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.
Normal Results Return to top
No growth of bacteria, viruses, or fungi in the culture is normal.
What Abnormal Results Mean Return to top
Abnormal results suggest that you have an infection of the bone marrow. The infection may be from bacteria, viruses, or fungi.

Considerations Return to top
Fluid (aspirate) or a piece of tissue (biopsy specimen) from the bone marrow may be sent to the laboratory for many different types of tests. These tests study how immature blood cells look, and how they are developing.
