On August 18, a scientific advisory committee of the Food and Drug Administration recommended approval of Hologic Inc.’s application for a new osteoporosis test that can predict whether women are at risk of developing the condition. The company’s Sahara Bone Sonometer uses ultrasound to measure bone density. This test, unlike others which measure the hip or spine, measures the density of a heel and is less complex than the X-ray tests currently used to detect osteoporosis. Approximately 28 million Americans, a majority of them women, have osteoporosis, or dangerously thinning bones. The FDA is not obligated to follow its advisory committee recommendations, but generally does.
