That is really odd Luckygirl. What a complete waste of everyone's time. I was prescribed Ad-Cal D3 when I was on steroids for PMR - this was a prophylactic because steroids increase the risk of osteoporosis. I was also prescribed alendronic acid, to be taken once a week; however, when I looked into the side effects I was shocked to find that it can cause necrosis of the jaw bone, and was terrified of taking it. So I told my GP of my fears and asked if I could have a DEXA scan. This showed no signs of osteoporosis so, with my GP's blessing, I never took the alendrotnic acid. I had another DEXA scan 3 years later, still no sign of osteoporosis.
On both occasions results were relatively quick - of course, if either test had shown osteoporosis, who knows if quantitative info would have been included in the results? It seems utterly pointless to me to carry out the tests without this information being relayed to your GP. I too would ask to be referred to your consultant again.
I do hope you get some answers sooner rather than later.
