2.2 Blood and bone marrow tests
The bone marrow tests are done as outpatient tests—this
means you do not have to spend the night in the hospital.
First, you may be given a sedative injected with a needle
into your vein. Your doctor will then clean the area of skin
where the biopsy will be performed. Next, you will receive
local anesthesia to numb the area of skin and bone
beneath. After the area is numbed, a hollow needle will
be inserted into your skin and then pushed into the bone
to remove the liquid bone marrow with a syringe. Then, a
wider needle will be inserted into the bone and rotated to
remove the solid bone and marrow sample. See Figure
5. You may feel some pain while the samples are being
removed and your skin may be bruised afterward.
