Your T-score is your bone density compared with what is normally expected in a healthy young adult of your sex. Your T-score is the number of units — called standard deviations — that your bone density is above or below the average.
Your Z-score is the number of standard deviations above or below what's normally expected for someone of your age, sex, weight, and ethnic or racial origin. If your Z-score is -2 or lower, it may suggest that something other than aging is causing abnormal bone loss.
Let's just say there is a whole lot of averaging of a whole lot of numbers with a whole bunch of standard deviation analysis thrown in for good measure.
And apparently, it also misses the real issue..the architecture of the bone:

The Bone Density Test Reality
Like other medical tests, the bone density test isn't perfect. While it can help predict who will have a fracture, and may need treatment or lifestyle changes, it's not foolproof. And, Templeton says, experts have discovered recently that the bone's architecture -- how well your bones are put together -- may also play an important role in predicting fractures.
"If you look at the women who have fractures, a lot don't have osteoporosis based on the DEXA [results]," Templeton says. Researchers speculate that in these cases bone architecture may be the problem -- but as yet, there is no realistic way to evaluate it.
Results also aren't as accurate if you are smaller or larger than average, Cosman says. So the test may underestimate your bone density if you are 5 feet tall or shorter, and may overestimate it if you are 5 feet 10 inches or taller.

Many private practices purchased these expensive DEXA machines, so they could the push some expensive bone density drugs ... and they are a bit stuck now for clients. Wish they would convert them to the body fat format..I'd go back for that
