I recently had my DEXA at park Nicollet in Burnsville and also received my TBS of 1.172. It also was on the hologic machine but this time there was no S/N listed. Since it could be a different machine, scores could be different than previous tests. I was able to find online locations in the area that have capability to do the TBS. Also, if you want a REMS, you can contact Osteostrong in Woodbury, Eden Prairie or Eagan. I go with the Dexa since they are well documented as a trusted source for measuring bone density.
