hello @esb13 you misread my post a bit. My DEXA is next month. I had the P1NP (which I believe might be good - having doubled after 3 months) and my surgeon looked at my xrays saying the spine bones appeared denser after six month. My surgeon DID NOT recommend DEXA because one's bone quality varies thru the body. Mine said I was improved and out of osteopenia but when my cervical spine had surgery last summer my C5 bone "fell apart in their hands." It was "paper thin" and they had to remove it. HOWEVER - we are hoping with the DEXAs going forward while be a gauge as to the effectiveness of the medicine. (the endocrinologist wants me to do it).
The size needle is 32 x 4mm Ultra Nano Fine. It is a dream! Just be careful you can bend the needle when you put it on the pen if you are not gentle.
As far as calling Radius - they were lame. They want all this info from YOU but they offer you nothing. You can ask for a scientist liaison from my provider, which I did a month AFTER I requested, but its been three months and I see none has appeared!
I really had to PUSH the endocrinology team for all of the tests I am now getting (all because of THIS forum!). I also had to enlist the help of my PCM (she is great but unknowledgeable about this specialty)
