Calcium Before Bone Test?

by Berkeley Wellness  

If you’re scheduled to have a bone mineral density test that includes the spine, don’t take a calcium supplement beforehand.

Many clinics as well as the American College of Radiology advise this because of concern that inadequately dissolved calcium in the intestines could be picked up by DEXA scans of the spine and misleadingly improve the results.

Even though the concern is largely theoretical, and any effect is likely to be small, to be on the safe side, don’t take calcium pills (including antacids such as Tums) within 12 to 24 hours of bone density scans that will include the spine.
