What is the z score for bone density scan?
Z-score is a standardized number that you may see on your bone density scan results or reports. Your bone mineral density (BMD) at each skeletal site of measurement is compared to a reference database of same age, race/ethnicity, and sex. The use of this calculated score depends on your age and menopausal status.

A stooped back or decreasing height can be a sign of decreasing bone density in your spine—and a loss of two inches or more of height may indicate that you have osteoporosis. If you experience stress fractures in your feet with normal activity or fracture a rib with no particular trauma, you should ask a doctor to check for osteoporosis or osteopenia. If you suffer an arm, wrist or a hip fracture with a fall from a standing position, you are very likely to have fragile bones and definitely need a bone density test.
How are osteoporosis and osteopenia diagnosed?
Doctors use X-rays to measure bone mineral density (BMD) and check for your risk of developing osteopenia or osteoporosis. Your BMD number will be compared to the BMD number of healthy, young, adult individuals of the same sex, and, in some cases, the same racial background. If your BMD is 2.5 units lower than that reference number, you have osteoporosis. If your BMD is between 1 and 2.5 units lower than the standard BMD, then you have osteopenia.
