@md2026 and @rajmayo22, my endocrinologist is Dr. Janice McMillan. She is part of the Prima Medicine group and they practice in Fairfax, VA. She ordered CTX, and I asked her to order blood work for P1NP, RBC Magnesium to make sure my cellular absorption of magnesium is optimal, and HS-CRP to check for low-grade systemic inflammation. Inflammation, as you know, can accelerate bone resorption and increase fracture risk.
