Is there a difference between a spinal tap and a bone marrow aspiration?

YES!!! You are confused because they are both done on your back but a spinal tap is to obtain the liquid that in in your nervous system around your spine and brain. A bone marrow aspiration is done in the iliac bone to obtain a sample of cells inside the bone cavity where blood cells develop and grow.
Yes. Spinal tap removes part of the cerebrospinal fluid (the fluid that surrounds the brain and the spinal cord) usually by placing a needle into the spinal column through the back and withdrawal of the fluid. Bone marrow aspiration is done typically by a much larger needle (trocar) which is inserted into the center of the hip bone (rarely the sternum) for the purposes of withdrawing the bone marrow.
SPINAL; BONE MARROW. A spinal tap does not enter bone. In a bone marrow aspiration, the needle is injected directly into the bone to extract the marrow.

Difficult to tell. From my reading, a blast percentage of 6% is needed for a sure diagnosis of acute leukemia.

Immunohistological studies can give more information. Need more info like blood cell counts. Read more...
