Where can we find out ultrasonic tester that measures bone density taken from the heel?
First of all you need to tell people where you live, as there are participants from a number of countries here, although site is a UK one. Secondly I think the usefulness of the heel reading has been pretty well debunked. It was a tool developed to help physicians quickly decide if a patient should be prescribed a bone med. It was developed by, wait for it, the bone med companies. At the very best all it could do is indicate that you might need to have a proper DXA scan, and even that is not reliable.
By the way before I knew this our local pharmacy offered from time to time a chance to have your heel measurement taken. This was some years ago and they haven't offered it for a long time.
Clarifying, even the need for a proper DXA scan cannot be relied upon from a heel reading. Not that the DXA scan can't be relied upon, which has it's own issues but is the best we've got at the moment.
