My doc doesn't do CTX. It seems most endocrinologists don't do that kind of blood work. I believe P1NP is an indicator of bone building and CTX is a measure of bone turnover. But docs don't seem to use these,

Yes a break after one or possibly two Reclasts depending on testing. I wonder, at this point, if my doc will do CTX and P1NP or what my doc means by "monitoring"....maybe DEXA? I am getting a second opinon next week and will ask.
