A bone density test, also known as a DEXA (dual-energy X-ray absorptiometry) scan, is a diagnostic test used to measure the density of your bones and to determine your risk of developing osteoporosis. Here are some general guidelines on how to prepare for this test:
Inform your doctor if you have had any recent X-rays or other imaging tests that used contrast material, as these may interfere with the results of the bone density test.
Avoid taking calcium supplements for at least 24 hours before the test, as they can affect the results.
Wear comfortable, loose-fitting clothing without any metal buttons or zippers, as you may need to remove these items for the scan.
Let your doctor know if you are pregnant, as the test is not recommended during pregnancy due to the use of radiation.
If you have had any recent surgery involving metal implants, let your doctor know, as the metal can interfere with the test.
You may be asked to avoid eating or drinking anything for a few hours before the test, depending on the specific instructions provided by your healthcare provider.
To perform the test, you will lie on a padded table while a scanner arm passes over your body to measure bone density in different areas, such as your spine, hip, or forearm. The test is non-invasive and typically takes only a few minutes.
It's important to note that every healthcare provider may have their own specific requirements and instructions for preparing for a bone density test, so be sure to follow their guidance carefully.
This test measures the density of a person's bones and is used to diagnose osteoporosis, a condition that causes bones to become weak and brittle. It may be recommended for women over the age of 65, men over the age of 70, or anyone who has risk factors for osteoporosis, such as a family history of the condition or long-term use of certain medications.
The report is usually available within a day or two.
Typically requires a visit to a healthcare provider or a laboratory for the test.
Fasting is usually not required for this test.
