Hi Phyliss: Boy I'm really sorry about this mess, but unfortunately it doesn't surprise me. I know if I were to go to a local lab where I lived, they wouldn't know anything about this, nor would they take any literature I brought.
If you can get your insurance to pay for 2 dexa's, one now and one in 30 days, that could give you a lot of info. You could find out what your current score is and also what effect stopping the med would have "if" any. IMHO I don't think stopping it for 30 days would make a big difference, since all the trials done on SR showed fracture prevention for 3-5 years after treatment; now I don't know what the dexa increases/decreases where at that point in time, but you could look it up through Serviers info. The Servier info should tell you what the dexas were after treatment stopped, if you don't already have that info.
That article that you are referring to, with the name Hoffman, which one is that? I looked at the 2 I have and can't find that name. In the Journal Clinical Densitom 1999 Winter;
2 (4): 371-9 it say's "The same adjustment factor (10% overestimation for 1 mol/mol% Sr) can be used for all presently available types of instrument and acquisition modes." The only problem is applying these adjustments to Strontium citrate, which I think is going to be hard to do. So far, I can't get anyone to say that SR is the exact same mineral composition as SC.
I wouldn't worry about your Drs reaction to having a dexa somewhere else, he sounds like a reasonable guy
and he must know that his patients treatment should be of utmost importance, however you accomplish that.
Hopefully the scanner co will provide the info you need, and you can go from there.
I wish I could get my insurance to pay for dexa's more often than every 12-24 months, so if your's will go for a baseline, and a repeat dexa that would be great.
