Osteoporosis is a common condition that causes bones to become weaker and more prone to fracture, and it often develops silently over many years without obvious symptoms. Bone density testing is the main tool physicians use to assess this risk before a fracture happens. This guide explains who is typically at higher risk, how bone density testing works, and when your doctor might recommend one.
Quick Facts: Bone Density Testing
Bone density (BMD or DXA) tests use a very low dose of X-ray to measure bone strength. Risk generally increases with age and is higher in postmenopausal women. The scan is quick, painless, and requires little preparation. OHIP covers bone density testing for patients who meet clinical eligibility criteria.
What Increases Your Risk of Osteoporosis
A number of factors can increase the likelihood of developing osteoporosis, including age, being postmenopausal, a family history of osteoporosis or fractures, long-term use of certain medications such as corticosteroids, low body weight, smoking, and limited calcium or vitamin D intake. Some medical conditions can also affect bone health over time. General information on osteoporosis risk factors and prevention is available from the Government of Canada.
How a Bone Density (BMD/DXA) Test Works
A bone density test, also called a DXA or BMD scan, measures bone mineral density at sites such as the hip and spine using a very low dose of X-ray radiation, far lower than a standard X-ray exam. The scan itself is quick, generally taking about 10 to 20 minutes, is painless, and does not require sedation.
Results are interpreted by a radiologist, compared against expected bone density for your age and sex, and reported back to your referring physician. Learn more about our bone density testing service in King City.
When Should You Get Tested
Your physician will generally consider factors such as your age, sex, medical history, and any risk factors when deciding whether a bone density test is appropriate, and how often follow-up testing might be needed. If you have already been diagnosed with osteopenia or osteoporosis, periodic testing can help track whether your bone density is stable, improving, or declining over time, which can inform treatment decisions.
