Osteoporosis Advice

[sahuaro]

Allan:
Osteoporosis is defined as T scores below -2.5. T scores compare your bone density to women in their 30's (yes, women); Z scores compare to women in your age range. I don't know if the interpretation of scores is adjusted for males, e.g., if, as a male, a T score of -2.5 would be interpreted as worse than the same score for a woman. Obviously, in many ways, this is a crude measure and docs don't figure in the standard error of measurement and other variables.
Since you have had previous tests, the question would be whether the change in your scores are within the standard error of measurement or beyond, i.e., is the change significant? (I don't remember the SE but I did find it online a while ago)
