69YO active F. My DEXA scores were very low (severe osteoporosis) and my endo refused to include TBS scores with it. I then got a REMS test and I was mild osteopenia. I then got another DEXA from another provider with TBS. DEXA scores are still terrible (and comparable to the first, even though all factors — machine, technician, radiologist--were different from the original scan), but my TBS scores were very good. So no clue what to believe.
