Bone Density Test | DEXA Scan
Bone density tests, or DEXA scans, can tell if you are at a higher risk for breaking bones or if you have osteoporosis. This painless procedure is the only test patients can use to tell if they have weakened bones or osteoporosis. Contact your provider if you believe you could benefit from a bone density test.
What is a bone density test?
A bone density test measures the calcium in the tested area of the bone. This determines the strength and durability of the bones. Bone density tests can tell if a patient is at increased risk for breaking bones. They can also determine if osteoporosis medication is working. Bone density can be tested in a number of places:
Some patients can have low bone density but not yet have osteoporosis. Doctors will work with patients and consider the need for osteoporosis treatment based on the results of the tests.
Bone density test process
Patients must not take any minerals or vitamins the day of the exam. Barium and radioisotopes exposure can also affect test results. The bone density in the spine and hip are the most frequently tested.
Patients are be tested by using a DXA machine. DXA machines give off low doses of X-rays and show bone density. The test should take approximately 15 minutes and can be taken at most hospital radiology departments and medical practices. Follow-up tests should be taken every two years to measure improvements or decreases in density.
