Bone marrow biopsy

Bone marrow biopsy is a technique to remove a small section of the tissue from the body to study it under the microscope for any further analysis and tests. This test is recommended by doctors if they see an abnormal result in the complete blood count of a person or for examining any other regular disease that might be present in the bone marrow. Bone marrow biopsies are used to check for blood disorders like leukemia, certain types of anemia or problems affecting the bone marrow such as multiple myeloma or polycythemia vera. Besides they can throw light on any infections or cancers that are originating in the bone marrow. A bone marrow biopsy aids in studying abnormal appearance and numbers of red blood cells, white blood cells or platelets in conditions such as thrombocytopenia. It is essential to keep the health care provider of any medications that are taken. A local anesthetic is usually given to numb the skin. A sedative may be prescribed to calm the patient throughout the bone marrow biopsy procedure.

Samples are usually taken from the hip bone after cleaning the area.

A biopsy needle is inserted into the bone.

Core of the needle is removed and the needle is turned in both the directions thus forcing a small sample of the bone marrow into the needle.

The needle is removed from the site and pressure is applied on that area to restrict bleeding and the area is bandaged.

There might some discomfort after the biopsy needle is removed as the anesthesia effect cannot reach the bone interiors.

Bone marrow biopsy will take about 20 minutes and after the biopsy you may be asked to lie down for another 60 minutes to check for bleeding from the site.

Results of bone marrow biopsties are available after 1 to 3 days. Normal results are indicated by normal numbers of mature and growing bone marrow cells. Abnormal results of a bone marrow biopsy are indicated by abnormal appearance of normal numbers of mature and growing bone marrow cells and presence of fibrous tissue in the bone marrow. There may be special stains that confirm infection in the bone marrow.
