8 Frequently Asked Questions About Bone Density Tests

8 frequently asked questions about bone density tests
A bone density test is a screening that helps determine whether a patient is suffering from osteoporosis. Osteoporosis is a disease marked by weak and brittle bones. A bone density test helps warn individuals of serious weakness in the bones and helps in getting it treated before facing the issue of a broken bone. In the past, doctors would wait until a patient suffered a broken bone or a fracture to test for osteoporosis.

8 Frequently Asked Questions About Bone Density Tests
However, now, prevention is key; a bone density test helps predict bone health and deterioration so that preventive measures may be taken to offset the effects of brittle bone diseases.

Let’s take a look at some of the FAQs on bone density tests.

How is a bone density test conducted?

  • A bone density test is called a DEXA scan.
  • It is a type of X-ray in which a small, portable machine measures the density of the bones in the body. It may even reach the smallest of joints such as those in the hands and feet.
  • The entire test takes anywhere between 10 and 30 minutes.

What does a bone density test reveal?

  • A bone density test is done for the following reasons:
  • It warns of the onset of osteopenia or osteoporosis.
  • It predicts a patient’s chances of suffering a fracture or a broken bone due to low bone density.
  • It confirms a doctor’s diagnosis of osteoporosis.
  • It reveals the progress of ongoing osteoporosis medication.
  • In some cases, the DEXA test may also reveal signs that cancer has spread to the bones.

Are there any side-effects of a bone density test?

  • There are usually no side-effects of this test.
  • However, after the procedure, some patients do experience an upset stomach, difficulty in swallowing, and heartburn.
  • In very rare cases, some patients experience additional joint and muscle pain after the procedure.

Who should undergo a bone density test?
A bone density test is recommended in the following cases:

  • For men and women above the age of 65.
  • For women who have just gone through menopause.
  • For a person who has been under a long-term prescription of certain steroids such as prednisone.
  • For the patients who have had a fracture post the age of 50.
  • For the patients who have lost height of around 4 centimeters or more in the past year; osteoporosis may cause compression fractures in the spine.
  • For the patients who have had a bone marrow transplant or an organ transplant, as anti-rejection medications interfere with the bone-building process.
  • For patients who suffer hormonal fluctuations.

  • The doctor can best advice on how often you may need to get the test done.

What is the meaning of T-score?

  • Bone density results come as T-scores. A T-score compares the patient’s bone density with the bone density of a 30-year-old individual.
  • A T-score of -1.0 and above is considered normal.
  • A T-score between -1.0 to -2.5 indicates low bone density or osteopenia.
  • A T-score below -2.5 indicates osteoporosis.
  • Always get the test results interpreted by a medical professional; never attempt to check them on your own.

Are there any precautions to take before the screening?

  • A bone density test is a painless procedure.
  • It is recommended that you avoid the intake of any calcium supplements 24 to 48 hours before the test.
