My endocrinologist, head of the dept. at a major hospital, does not do bone turnover marker tests at all. He says they are not useful.
I met with Keith McCormick, author of The Whole Body Approach to Osteoporosis, and he recommended that I get baseline bone turnover maker tests, to help assess effectiveness of drugs. I asked my PCP to order them.
Mine were all in the reference range. Normal. P1NP was 54, reference range 16-96 for postmenopausal.
Collagen CTx 324 pg/ml with reference range 104-1008 for post menopausal.
Also parathyroid (PTH) 50 (ref. 15-79) , calcium 9.7 (ref. 8.9-10.3) and Vitamin D 52.
So with severe osteoporosis and fractures, these tests did not tell me much. Nothing amiss at all. McCormick said we could compare levels while on Tymlos but I have not done that as yet.
Thanks for the information. As an aside what are you taking for bone health? I'm taking a basic vitamin, a bone health trifecta supplement of calcium/vitamineD3/vitaminK2 and a biotin/zinc supplement. I added lysine when covid as the virus is RNA-based.
But wonder about collagen supplements, about which I know nothing. Are you taking it? Anything else I should add in your opinion? Thanks.
