Not sure how this relates to Osteoporosis, but I had the test done through a clinical trial named Pathfinder 2. I think it's still running, here is a link https://joinpathfinder2study.com/ . It was free through the trial and luckily, one of the locations was at my local hospital.

I did ask the nurse about the results they were getting and she said most were coming back negative. Mine came back negative. For other reasons, I did get a PET scan a few months later and it did not show any cancer. Just one data point.
