Usually health plans will pay for bone density testing every two years, but if your bones are in good shape, your doctor may extend the time between tests. In 2012, a highly respected group of researchers reported on following nearly 5,000 women over 65 who did not take an osteoporosis drug and did not have osteoporosis.
How often should bone mineral density (BMD) tests be performed?
List of authors. Although bone mineral density (BMD) testing to screen for osteoporosis (BMD T score, −2.50 or lower) is recommended for women 65 years of age or older, there are few data to guide decisions about the interval between BMD tests.
What is the BMD for osteoporosis?
When BMD is measured, use DXA measurement (spine and hip) Osteoporosis should be diagnosed based on presence of fragility fractures in the absence of other metabolic bone disorders or a T-score of -2.5 or lower in the lumbar spine, femoral neck, total hip, and/or 33% (one-third) radius even in the absence of a prevalent fracture
How often should we screen for osteoporosis in advanced osteopenia?
For those with advanced osteopenia at the start, about 10% had developed osteoporosis within a year, suggesting that 1-year screening intervals might be advisable for this group.
How many bone density tests are needed to diagnose osteopenia?
Researchers divided the women divided into 4 groups based on initial bone density tests that were either normal or showed mild, moderate or advanced osteopenia. They were given 2 to 5 bone density tests at varying intervals during the 15-year study period.
How often should BMD be tested?
How Often Should I Get Tested? If you are taking medication for osteoporosis, expect to have a bone density test every 1 to 2 years. Even if you don't have osteoporosis, your doctor may suggest that you get a bone density test every 2 years, especially for women during or after menopause.
When do you repeat BMD?
It is appropriate to recommend a repeat BMD test by dual energy X-ray absorptiometry (DXA) after two years for patients at risk of developing osteoporosis, to assist in re-evaluation of fracture risk.
How often should you get a bone density test if you have osteopenia?
If you're diagnosed with osteopenia, you will need regular bone density tests to monitor bone health, usually every two to three years. Not everyone with osteopenia develops osteoporosis. Changes to your lifestyle can keep bone loss to a minimum.
How often should you repeat a DEXA scan?
Don't routinely repeat DXA scans more often than once every two years. Initial screening for osteoporosis should be performed according to National Osteoporosis Foundation recommendations.
When do you repeat BMD after bisphosphonates?
Repeating BMD testing within 3 years of starting treatment with bisphosphonates is unnecessary and potentially confusing. 1 By far most patients taking bisphosphonates will have adequate increases in BMD after 3 years and will have a reduced fracture risk regardless of BMD changes.
How do I monitor my BMD?
Bone mineral density assessment by dual-energy X-ray absorptiometry is the most widely available and best validated clinical tool to diagnose osteoporosis, assess fracture risk, and monitor the skeletal effects of medications that reduce fracture risk.
How often should a 70 year old woman have a bone density test?
If you are a woman 65 or older, a bone density test is recommended, with a repeat test generally performed two years after the initial test, although this interval may change depending upon any treatments being administered.
How often should a 75 year old woman have a bone density test?
And they found that women with a healthy initial test could wait as long as 15 years before getting a second screening. But women deemed at moderate risk should get tested about every five years. And women at high risk should get tested more often, perhaps even annually.
How long does it take for osteopenia to turn into osteoporosis?
Of patients with osteopenia, 23.7% progressed to osteoporosis; median progression time was >8.5 years. Progression time was >8.2 years in “low-risk" tertile (T score between −1.1 and −1.6 SD), >8.5 years in “middle-risk" (between −1.6 and −2), and 3.2 years in “high-risk" (from −2 to −2.4) (p<0.0001).
How much bone density does a T score of 1.0 mean?
This study’s results do not apply to you if you: One T-score unit (e.g. -1.0) is roughly 10% of one’s bone density. Once you are a few years beyond the age of menopause, assuming you are generally healthy, your expected bone loss is 0.5% per year or 5% in 10 years.
How long does it take for bone loss to accumulate?
Over the years, the researchers routinely measured bone density. The new report tells us that, in this age group, bone loss is really quite slow — it takes many years for bone loss to accumulate. The average older woman with normal bone density loses only about 5% of her bone density in 10 years.
Is bone density important?
Bone density is important, but it is not the whole story. The study looked at the progression of bone loss in women who began with relatively normal bone density scores — all had T-scores better than –2.5, a level indicating osteoporosis.
How often should you repeat your bone density test?
A study of nearly 5,000 women now reports that patients with healthy bone density on their first test might safely wait 15 years before getting rescreened. Osteoporosis is a disorder marked by weakened bones and an increased risk of fractures.
How many bone density tests were done in the 15 year study?
They were given 2 to 5 bone density tests at varying intervals during the 15-year study period.
How many women with low bone density develop osteoporosis?
As reported in the January 19, 2012, issue of the New England Journal of Medicine, the scientists found that less than 1% of women who initially had normal bone mineral density went on to develop osteoporosis during the study. Only 5% of those with mildly low bone density at the start made the transition to osteoporosis.
What is the disorder of weakened bones and an increased risk of fractures?
Osteoporosis is a disorder marked by weakened bones and an increased risk of fractures. More than 40 million people nationwide either have osteoporosis or are at increased risk for broken bones because of low bone mineral density (osteopenia).
Why is osteoporosis considered a silent disease?
Osteoporosis is often called a “silent disease” because it usually progresses slowly and without symptoms until a fracture occurs. When low bone density is identified early through screening, lifestyle changes and therapies can help protect bone health and reduce the risk of fractures.
Which type of tomography provides accurate measurements of bone density in the spine?
There are different models of DXA instruments, and the bone density measurements are easier to compare if they have been taken on the same model. Quantitative computerized tomography — This is a type of computed tomography (CT) that provides accurate measures of bone density in the spine.
Why do we need bone density tests?
Bone density tests help health care providers spot bone loss in people who might otherwise have no symptoms. The tests are painless, quick, and safe, and they can alert people to bone loss before they have a fracture. The tests are also useful in tracking the effects of medications used to manage bone disease.
How many fractures does osteoporosis cause?
Each year in the United States, osteoporosis leads to approximately 2.0 million fractures, including [ 1 ]: ● 550,000 fractures of the vertebrae, the bones in the spine.
Why is bone density important?
The tests are important, because they can alert you to problems with your bones before you have a fracture.
How old do you have to be to test for fracture?
In addition, there are certain characteristics that put people at higher risk for fracture, so health care providers sometimes recommend testing in men or women younger than 65 years who have one or more risk factors. (See "Screening for osteoporosis in postmenopausal women and men" .)

Can you take calcium supplements before a blood test?
It is also recommended that you avoid taking calcium supplements in the 24 hours before your test, as these supplements can sometimes interfere with the images. The amount of radiation that's used is minimal, amounting to roughly the same radiation that an average person gets from the environment in one day.
What is the recommended bone mineral density score for osteoporosis?
Although bone mineral density (BMD) testing to screen for osteoporosis (BMD T score, −2.50 or lower ) is recommended for women 65 years of age or older, there are few data to guide decisions about the interval between BMD tests.
How long does osteoporosis last?
As expected, the estimated time to osteoporosis decreased with increasing age, so that an interval of 3 years, instead of 5 years, might be considered for women 85 years of age or older who have moderate osteopenia. Although the trends for BMI and estrogen use were also significant, they were less clinically relevant.
