What Is a Bone Density Test?

A bone density test measures the strength or weakness of bones by assessing X-ray absorption (DXA), a type of bone X-ray. This test uses low levels of radiation and involves passing a scanner over the body while lying on a padded table.

A bone density test is recommended:

For all women aged 65 years and above.

For women under 65 with risk factors increasing the chance of developing osteoporosis.

For individuals with risk factors that increase the likelihood of developing osteoporosis.

Factors increasing the chance of developing osteoporosis:

Menopause and lower hormone levels.

If you are a man with health issues related to bone density loss, such as rheumatoid arthritis or chronic kidney or liver diseases.
