If your mind is popping with the question-Why can’t you take Calcium/ vitamin D supplements before the bone density test, it is because there may be instances that the calcium supplement is not completely dissolved. It can be interpreted by the DEXA instrument as an extra bone that in turn produces an inaccurate reading.

Though bone densitometry tests use a low dose of ionizing radiation, there are few risks associated with it. Always tell your health-official about the previous CT Scans and other types of X-Ray scanning. If you think you are pregnant, let your health-provider know beforehand. During pregnancy, the exposure to radiation must be less so that there are no birth defects. There are certain factors that need to be kept in mind while going for a bone density test. They include – metal jewelry, any kind of body piercing, Calcified arthritic sclerosis, healed bone fractures and any metallic clips from previous stomach surgery.

In a nutshell, Bone Mineral Test determines the bone mineral density. Your BMD has two norms generally-such as the healthy young adults – T score and age matched adults, your Z score.
