How long to wait before re-testing bone markers
I had my first CTX /P1NP blood work in June. The results were high/low respectively. Since it was the first time I had the bone markers tested, I have no comparisons to when I first stopped taking a proton pump inhibitor a year earlier.
I am having the REMS ultrasound bone scan test in February and will forward blood work to the doctor's office. Should I re-test the bone markers in December or January so there is a comparison?
Or in general how long does one wait to re-test bone markers? My PCP doesn't know about bone markers, just ordered the tests per my request, so that is why I am asking here.
