Bone (Definition)

Bone is a living growing tissue made mostly of collagen (protein that provides soft framework) & the mineral calcium phosphate that adds strength & hardens the framework. Two types of bone are found in the body; cortical (dense compact outer layer) & trabecular (makes up inner layer, ...Read more

X ray of broken bone showed hole in bone biopsy done and was neg for bone cancer. Recent blood test showed low white blood count. Reason for concern?

X ray of broken bone showed hole in bone biopsy done and was neg for bone cancer. Recent blood test showed low white blood count. Reason for concern?

Evaluation warranted: Depending on how low the white count, it would be wise to continue to be followed by a primary health care provider and/or hematologist. It will likely return to normal, but it should be followed. ...Read more

How does the bone density test define osteoporosis?

How does the bone density test define osteoporosis?

Only partly: The dexa scan gives the bone mineral density at the hips, spine and forearm. These scores can predict osteoporosis: 't-score' of less than -2.5 is considered osteoporosis. However, many people suffer osteoporosis fractures despite having better bone densities. So, we also use other factors: age, ethnicity, size, family history, prior fractures, smoking, alcohol, other conditions to predict risks. ...Read more

Does a bone density test usually hurt?

Does a bone density test usually hurt?

No: The best bone density test, called dxa, does not use any needles. A person lies on a table and a very small dose of radiation passes through the lower spine and hip to measure bone density. It is painless. ...Read more

What does satisfactory blood test result mean? Full blood count, bone profile and kidney

What does satisfactory blood test result mean? Full blood count, bone profile and kidney

Lab results: Lab results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Depending on the test, a normal value may rule out disease but other normal results do not necessarily mean lack of disease. It would be useful to have the actual results. ...Read more

Does a bone marrow transplant change your blood cells?

Does a bone marrow transplant change your blood cells?

Who is donor?: This depends--if it is an autologous transplant where a patient receives their own cells then the immune system and blood type are unchanged. An allogeneic transplant comes from donor different than the patient. In this case the immune system changes. Also, if the donor has a different red cell type then the recipient's blood type will change too. ...Read more

What does a "low normal" bone density test mean?

What does a "low normal" bone density test mean?

Very little!: When the world health organization arbitrarily set a level of bone mineral density (bmd) below which a person was said "to have" osteoporosis, the opportunity was immediately seized by interested parties to declare a range better than that density but adjacent to it as "osteopenia". Above that is called "normal" bmd is a continuum! normal is normal. Low normal means normal. ...Read more

Thick blood , high inflammation levels abnormal liver function in all 3 blood tests, test back pos for blood clot on lung after dye test, back neg?

Thick blood , high inflammation levels  abnormal liver function in all 3 blood tests, test  back pos for blood clot on lung after dye test, back neg?

This is serious: I trust the dye test was a pulmonary angiogram that demonstrated a pulmonary thromboembolus, and it has also been determined that you have hypercoagulable blood. This is a major problem that will require work with your primary care physician and probably long-term medical management -- more than healthtap can do. Hope you do not smoke. The "inflammation" & liver labs need to be addressed in time. ...Read more

My son's blood test showed leukocytes 3, lymphocytes 1 and neutrophils 0.6. When will a bone marrow test be indicated? This was the 3rd abnormal test

Bone marrow test: May not be indicated as a next step, before that, more evaluation of his clinical condition by a hematologist and an a clinical immunologist, if available. His development, clinical status, immunization status need assessment first, avoid live vaccines for now till diagnosis is final, viz oral polio, MMR, Yellow fever, BCG and ? Menigitis vacccines.

How accurate is the heel bone density test?

How accurate is the heel bone density test?

Depends: The diagnosis of osteopenia and osteoporosis are generally made from a dxa machine that tests the spine and hip. The heel test is done with a portable device that is used to screen for bone loss. Although accurate statistically, it is not used clinically unless there is not a device that will measure the spine and hip. The heel should not be used to follow the rate of change in the bone density. ...Read more

Should men get bone density tests?

Yes: If there is physical evidence for thin bones as when a man's bones look thin on x-ray or there is a history of fracture with minor injury or there has been a loss of 1.5 inches of height, or if there are other risks for osteoporosis such as long-term treatment with steroids like Prednisone or hormonal treatment for prostate cancer or hyperparathyroidism, dexa scan absolutely should be done. ...Read more
