How to Prepare for a Dexa Scan

Dexa Scan tests are similar to X-ray tests. They are used to test bone density and analyze whether a patient has osteoporosis or osteopenia. They are accurate and can show bone loss at less than 20 percent. They do not generate the same exposure as regular X-rays and are considered safer. This test generally costs about $250 and is covered by most types of medical insurance and Medicare.

Instructions

• 1

  Stop all calcium supplements. You must refrain from taking any calcium supplements that you take regularly at least 48 hours before your scheduled Dexa Scan test. These calcium supplements can skew the Dexa Scan test results. You can continue to eat your normal diet as this will not affect the test results.

• 2

  Remove jewelry. Dexa Scan tests are still similar to X-rays, and you are not allowed to wear any type of metal while having the procedure done. This includes earrings and any other jewelry, regardless of where it is on your body. You may want to wear clothing that is not clingy and is comfortable on the day of your test. Choose clothing that also does not contain any metals such as zippers, metal buttons or belts.

• 3

  Inform your technician of any injuries you have had, including back and hip injuries. This will ensure that these injuries are not mistaken for new fractures due to brittle bones. You also need to make sure that you inform the technician of any tests you have had recently that involved barium, contrast materials or any dyes. There is a minimum 10-day waiting period between Dexa Scan tests and any other radiological tests.

• 4

  Inform the technician or your doctor if you know you are pregnant or suspect you might be. X-ray tests are generally discouraged for pregnant women.
