Avoid taking any calcium the day of your exam, as false or inaccurate results may occur. Do not take calcium supplements or vitamins containing calcium until your test is complete. Wear comfortable clothing preferably without snaps, buttons or zippers at the waist.
Some other radiology exams can interfere with your bone density test. Any exams that involve barium or IV contrast (dye) should be scheduled after your bone density test or at least one week prior.
The International Society for Clinical Densitometry currently recommends that a bone density test be done for:
- All women age 65 and older.
- All men age 70 and older.
- Anyone with a fragility fracture.
- Anyone with a disease, condition or medication associated with osteoporosis.
- Anyone who is considering therapy for osteoporosis, if bone density testing would facilitate the decision.
- Women who have been on hormone replacement therapy for prolonged periods.
- Anyone being treated for osteoporosis, to monitor the effects of therapy.
