vansks, I just looked at U,tra Lab Tests and the P1NP is on their list of bone and joint tests. It is spelled out.... Procollagen Type 1 Intact N Terminal Propetide.

I agree with kristie2 that bone biomarkers are very important. My PCP would not order them for me at first. It took a lot of arm twisting, and my visit to McCormick, that prompted my PCP to order these tests. Long story short, my PCP would have put me on the wrong osteo med. The P1NP test solidified the need for a anabolic med. I'm now seeing an endocrinologist. Both the endo and McCormick have recommended Forteo.
