Bone marrow is the flexible tissue found in the interior of bones. In humans, red blood cells are produced in the heads of long bones, in a process known as hematopoesis. On average, bone marrow constitutes 4% of the total body mass of humans; in an adult weighing 65 kilograms (140 lb), bone marrow accounts for approximately ...Read more
What is the difference between bone marrow aspiration n bone marrow biopsy what tests are performed in both?
During and After: I had bone marrow aspirated twice. Under local anesthesia the answer is kinda - it is the most unusual sensation and feels like someone is sucking the marrow out of your hip. While it was unpleasant, it was not terrible. As a bone marrow donor the answer is yes post-operatively the areas of the hips are very sore while there is no pain while the bone marrow is aspirated under general anesthesia? ...Read more
I'm an 18 y/o male and I'm getting a bone marrow aspiration and byopsie. How badly will this hurt?
Sampling of marrow: This is a removal of the liquid marrow within the bone. A needle is inserted through the skin and then into the bone. From this site, marrow is withdrawn. The bone typically used is the hip bone. The marrow looks like blood, but is made up of a very different group of cells. ...Read more
Counting 500 cells manually in an bone marrow aspiration there are 14 percent plasma cells what does this mean?
Plasma cell cancers: Normal bone marrow has 10% could suggest plasma cell cancers. Definitive diagnosis, however, should be interpreted in the context of other data such as immunofixation. Smoldering multiple myeloma has >10% plasma cells (malignant cells) in BM without end organ damage. Amyloidosis and some lymphoma can also have elevated plasma cells in BM. ...Read more
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. ...Read more
Completelt different: Spinal tap is done by putting a needle to the lumbar (lower back area) spinal canal space- to obtain cerebro spinal fluid. Bone marrow aspiration is done on the pelvic bone/hip bone - by putting a needle into the bone- going to the marrow space and aspirate the blood part inside the bone (i.e. Marrow). The indication, procedure, technique, etc area different. Completely different procedures. ...Read more
Dry Tap: This refers to the physician not being able to aspirate any liquid bone marrow when obtaining a sample. This can be caused by chemotherapy causing the bone marrow to be empty, scarring of the bone marrow (fibrosis), prior radiation to the area of the procedure, and sometime to persistent or recurrent leukemia. ...Read more
Pls hematologist opinion blast cells less than 1 percent but 14 percent plasma cells in bone marrow aspiration means?
Difficult to tell.: From my reading, a blast percentage of 6% is needed for a sure diagnosis of acute leukemia. Toxins, allergies, infections, diabetes, liver disease, inflammation, and anemias can all cause a leukeamoid reaction that causes plasmacytosis in the bone marrow usually lower than 20% but sometimes up to 50%. Immunohistological studies can give more information. Need more info like blood cell counts. ...Read more
Hi there, my question is will a blood transfusion made in a two weeks time before the bone marrow aspiration would affect the testing?
Not much: The bone marrow aspiration will assess the production of rbc, and transfusion will not impact those findings to any clinically meaningful extent. ...Read more

My blood counts are low and the hematologist did a bone marrow aspiration and biopsy even though I have no symptoms. Is this normal?
Dx chronic anemia. Last bone marrow aspiration 4 yrs ago. Have had erethropoetin output 1-4since then hgb generally 8.0-11.1 hct relative. Feel hem/onc Dr ignoring me should I get updated aspiration? Many symptoms-chest pain, extreme exhaustion. Epo output
Chronic anemia: The main reason to repeat the marrow biopsy would be if there was a change in your disease- more refractory, more wbc, lower plts, etc. If the underlying chronic disease cannot be treated or is unknown, then using EPO to treat and monitoring hgb is quite reasonable management. But it sounds like you may wish to have more explanation. Making and apmt to talk or ask questions is OK, or consult here. ...Read more
I have low epo output and extremely low iron stores in bone marrow (aspiration done). Chronic anemia-can be as low as 6.2-8.2 on regular basis Can this affect my teeth? It seems since my dx 8-10 yrs ago I have had terrible tooth decay and poor gums. Of cor
It could make you more susceptible to gums disease. It shouldn't affect your teeth unless something you are taking is causing dry mouth. Things that could affect your susceptibility to decay are menopause, vomiting, and heart burn.
You don't have to have problems if you take care of your teeth. ...Read more
Depends on purpose: How many tests can be done from blood? Millions. How many tests can be done from a bone marrow biopsy (BMB) specimen? Many? What tests should be done? It depends on 1) purpose for performing the BMB and 2) the findings the pathologist sees on morphologic examination of the aspirate & biopsy. Tests may include stains for iron or congo red (amyloidosis) as well as flow cytometry, cytogenetics, FISH. ...Read more
Nothing...: They are literally one and the same... The aspiration is the procedure... And then the pathologist looks at the sample as a biopsy specimen. ...Read more
The normal bone marrow is a mixture of cells and fat. Hypocellular marrow means the marrow has fewer cells in the bone marrow space that is expected for that patient's age.
There are many causes for this including nutritional deficiencies, bone marrow failure syndomes, pre-leukemia (myelodysplasia), prior chemotherapy, toxins and medications. ...Read more
Can any doc tell me what's meant when a bone marrow biopsy/aspiration report shows hypocellular marrow?
Bone marrow: Bone marrow cellularity refers to how much of the marrow is making blood cells, and how much is fat. As people age, it tends to decline and move more centrally. Severe hypocellularity may indicate aplastic anemia or even leukemia, which needs treatment. Lesser degrees may or may not, depending on other symptoms and lab findings. ...Read more
Would reviewing the bone marrow n aspiration slides by a better pathologist give a clearer picture how to fish tests help in myeloma?

Bone marrow biopsy/aspiration (chronic cytopenias/fatigue) f/u appt delayed 4 karyotyping. Is that usually to check CML or what else is possible? Thx
Karyotype important: There are many things that cause low counts. CML isn't one of them - that causes high counts. Getting the genetic testing is very important for making an accurate diagnosis no matter what the diagnosis. I always make my patients wait for that before they come in for their follow-up appointment. I know it's hard to wait, but it's better to get the full and accurate picture all at once. ...Read more
