In this case, I think you could go back and ask Quest to run your original order for free since they messed up. Although it's best to get both done at same blood drawing, it's good to know where your ctx stands.
Every other day dosing - did you have a baseline for p1np and ctx, and have them tested periodically thereafter?

The mistake would be an internal one with Quest. Ask-crew wouldn't have the answer. If the lab report has written CTX instead of P1NP or if they are giving you the CTX in mcg/L it is a simple error, but Quest has to provide the answer.
It's excellent that you are looking at your labs so carefully.
@06111945cc Thanks for clarifying! It doesn’t seem there are any publications on every other day dosing of Forteo, although it has been studied for some other dosing variations with successful bmd gains. This makes the info from your therapy so unique. 2mo into your therapy, P1NP was up 39% which is great! The interesting one is CTX at 2mo - it went down 47%. This change in CTX is in contrast with what’s seen in clinical trials for daily dosing of Forteo - CTX usually increases somewhat but less in magnitude compared with P1NP during early months’ Forteo therapy. No matter what the reason(s) behind your CTX change is or the fact that it went down, you were in anabolic window for sure at 2 month of Forteo. A reduction in CTX was even better for anabolic action. P1NP of 80 on 9/13 is indicating this bone marker came back down to baseline - this seems a bit earlier than what happened with daily dosing in trials. Perhaps this is a result of every other day dosing? Different dosing regimen could result in differences in btm response pattern.
What’s your endo’s opinion about your dosing and btm readings? Hope you do a DXA at 12mo Forteo to get a confirmation of bmd improvement. That will be a great holiday gift!

That is the results for your P1NP and not for CTX.

3 ReactionsP1NP: Procollagen Type 1 Intact N Terminal Propeptide
CTX: Collagen Type 1 C-Telopeptide
Mystery solved. What is your CTX reading @06111945cc? What osteodrug are you currently on?
Thank you!
I took the printed order for the CTX test to Quest.
Instead of running the CTX test they ran the test for P1NP!
Hence my confusion.
Bless you for understanding. 🙂

You asked what drug I’m taking.
I am taking Forteo. (Every other day as I can not tolerate taking it everyday.)

@06111945cc was your starting date 12/27/2022 or 12/27/2023? Second CTX on 2/22/2024?
