@babs10 my doc only did CTX at my request after 8 months of fosamax. Now after about a year after reclast he is doing that test. After fosamax CTX was 58, after reclast it is 76, he is thrilled with that. I asked about getting another yearly DEXA scan but unless the “doctors” at the insurance companies allow it I have no idea if reclast helped a little, or a lot, or hardly at all. He did point out that since my one bad number was -3.5 (others -2.6 to -2.8 before reclast) that number could not have possibly changed enough to change the course of treatment. I am scheduling an out of pocket DEXA since I can’t stand not knowing my numbers (good or not so good) after treatment with a very powerful drug. After they tell us DEXA is the gold standard, BTMs seem hit or miss?
