What screening test is used to assess for osteoporosis in older women?

The screening test used to assess for osteoporosis in older women is the dual-energy X-ray absorptiometry (DEXA) scan. This method measures bone mineral density (BMD), which is critical in diagnosing osteoporosis and predicting the risk of fractures. DEXA scans are recommended for postmenopausal women and older adults due to their accuracy, low radiation exposure, and ease of use.

In older women, the risk of osteoporosis increases significantly after menopause due to hormonal changes that affect bone density. The DEXA scan provides a score that indicates bone density compared to the average peak bone density of a healthy young adult, allowing healthcare providers to make informed decisions about prevention or treatment strategies for osteoporosis.
