Bone density scans offer doctors a quick and non-invasive way to gauge bone health. Learn how to prepare for a bone density test so you are ready on the day of your scan.
How Do You Prepare for a Bone Density Test?
There is minimal preparation needed before a bone density test. Following a few simple steps can ensure that your procedure goes smoothly and you get the best results.
Stop Calcium Supplements
Calcium supplements can affect the results of your scan. You should stop taking them at least 24 hours before undergoing a bone density test. This rule applies to all calcium supplements, including over-the-counter antacids like Tums and Rolaids, and some multivitamins. Be sure to get a medical provider’s permission before stopping any prescription supplements.
Choose Comfortable Clothing
You need to wear loose, comfortable clothing for a bone density scan. This will help you get into and stay in position during the scan.
Avoid items with metal buttons, snaps, zippers, or decorations. You should also opt for a wire-free bra if possible. DEXA scanners for bone density use X-rays, and metal objects can interfere with the images.
Inform Your Doctor of Other Tests
Some other tests can also interfere with bone density tests. You should inform your provider if you have undergone any of the following in the two weeks leading up to your scan:
- Barium exams
- CT scans with contrast
- Radioisotope scans
Rescheduling the appointment may be necessary to get the most accurate results.
What Can You Expect During a Bone Density Test?
Most doctors use a DEXA Scan to measure bone density. Understanding bone density is important for preventing falls and the resulting fractures. The DEXA scanner uses low-level X-rays to take images of the centers of your bones, most commonly the hips and lower spine. Some doctors may order scans of your forearm to test for specific medical conditions.
During the test, you will lie on a table while a scanning arm passes over your body. The technician may put a bolster under your knees for added comfort or may ask you to move into specific positions. A typical scan takes between 10 and 20 minutes from start to finish. The most important thing you need to do is lie very still so the technician can get the clearest possible images.
Do You Need To Follow Up After Your Bone Density Test?
It is important to follow up with your provider to discuss your scan results. It typically takes between two and three weeks for doctors to receive and interpret the results.
This follow-up visit is a good time to ask questions about any concerns and learn more about the importance of balance and physical activity for older adults. Try to schedule the appointment at a time when you won’t be rushed, and you can have someone accompany you if needed.
