Excerpt from Strong Women, Strong Bones: Everything you need to know to prevent, treat, and beat osteoporosis Chapter 5: Put your bones to the test

Bone density is the best single predictor of future fractures. Density accounts for about 80 percent of the strength of your bones. The best bone density tests predict fractures more successfully than cholesterol levels predict heart attacks or blood pressure predicts stroke. Yet these tests are underutilized, and insurance doesn't always cover them. As a result, less than 10 percent of people with significant bone loss are aware of their problem. 2br Important as these tests are, not everyone needs to be tested right now. Should you have a bone density test? The answer is Yes if:

You have symptoms that suggest osteoporosis, such as bone fractures or loss of height.

You're beginning hormone replacement therapy or other treatment for your bones. Or you're planning to stop HRT.

You have significant risk factors other than being a woman.

You're in peri-menopause or menopause.

Several different tests are used to measure bone density, which is also referred to as bone mineral density or BMD. All these tests are safe, painless, quick (no more than 10 to 20 minutes), and precise.

This chapter of Strong Women, Strong Bones describes the most common bone density tests, explains how to interpret the results - and provides tips for getting your insurance to cover the cost.
