Everything you need to know about bone density tests


As we get older, our list of vital medical tests gets longer and longer. Because we’re so busy, we tend to forget about our check-ups, or we may think we don’t need them because we don’t show any symptoms.

Whatever the case, chances are that you might have been skimping on your bone health and bone density tests. Here is all you need to know.

What is the bone density test?

The Bone densitometry or DEXA scan is an examination to help diagnose osteoporosis (brittle bones), which is a condition where bones become weak to the point of breaking. The purpose of the test is to identify the risk of osteoporosis and fractures, so that a treatment plan can be put into place.

How is the scan done?

It’s a simple, painless procedure where the patient lies on a padded table with an X-ray generator positioned underneath and an imaging device above them. The detector slowly passes over the hip and spine, generating images on a computer monitor. The DEXA bone density test is usually completed within 10 to 30 minutes.

When should I start going for a bone density scan?

According to the National Osteoporosis Foundation (NOF), a bone density test is generally recommended for women 65 and older, and men 70 and older, or if you break a bone after the age of 50. You might also want to consider having a scan earlier if you are at risk for osteoporosis, or if you’ve had a total height loss of 4cm since the onset of menopause.

How regularly should I go for a bone density scan?

You should preferably have a scan every one to two years, and within a year if you’ve started a new treatment plan for osteoporosis.

Where should I go for my bone density scan?

Your doctor will be able to advise you where to make an appointment.
