FAQs
What does a bone density test measure?
A bone density test measures bone mineral density (BMD), indicating how much calcium and minerals are packed into your bones to assess strength and fracture risk.
How is a bone density test performed?
You lie on a padded table while a DXA machine passes low-dose X-ray beams over key areas like the hip and spine. The process is painless and takes about 10 minutes.
Who should get a bone density test and when?
Women are generally advised to get tested starting at age 65, or earlier if they have risk factors such as early menopause, steroid use, or family history of osteoporosis.
Are there risks associated with a bone density test?
The test uses a very low dose of radiation, comparable to a few days of natural exposure, and is considered safe for most adults.
Can a bone density test detect conditions other than osteoporosis?
While primarily for osteoporosis and fracture risk, it can sometimes reveal fractures or hint at other bone diseases like Paget's disease, but it does not detect cancer.
