bluebonnet242,
sorry, I just realized that I hadn't answered your question fully.
I've had five PTH intact serum tests since July23. One was before he prescribed and one before I began treatment in February. He runs these tests at close to three months and then at nine months:
CTX
P1NP
BSAP
CMP comprehensive metabolic panel
CBC
PTH intact
and Lipid panel
Vitamin D
The gentleman is thorough. Usually my labs and appointments are a little off because we both travel in different directions. When I come in he has already seen everything. His practice is osteoporosis only.
I don't know how many of these labs are necessary. He is interested in statistics doesn't compare CTX to P1NP and doesn't use them for prescribing direction.
Good thinking to get the d levels checked. PTH makes very good use of D and can leave you low. My D didn't drop until a year in. You might ask for a CMP for the renal information. See if the PCP will order a PTH intact. You have to give them something to say no to.
I'm afraid that you may be experiencing practice "norms."
Great drug. Wishing you luck.
