Dexa Scan/Calcium Levels
I had a total thyroidectomy and partial parathyroidectomy about eight months ago.  I also have osteoporosis.  My endocrinologist wants me to have a Dexa scan.  I have read that in preparation for a Dexa scan, one has to stop calcium supplements 48 hours prior.  I take 1800 mg. calcium citrate along with a prescription Vit. D (Calcitriol) because my parathyroids have little function.
I am concerned that my calcium levels will drop too low if I stop the calcium for 48 hours.  Does anyone know how long calcium remains circulating?
Thanks for any info!

Hmmm -- I have had several dexa's over the past 8 yrs.  I've never been told to stop taking my calcium prior to the test.  You might want to check that with your doctor or the lab performing the test.
