Bone Mass Density Test for Osteoporosis Diagnosis

  • BMD 4

Our previous blog article spoke about Osteoporosis. Let’s take a look at the BMD test used to diagnose Osteoporosis.

What is BMD (Bone Mass Density) DXA (Dual-Energy X-Ray Absorptiometry)?

This is the most accurate way to measure BMD. DXA can measure as little as 2% of bone loss per year. It is fast and uses very low dose of radiation.

BMD measurement is painless, non-invasive and involves minimal radiation exposure.

Measurements are most commonly made over the lumbar spine and hip joint. The forearm may be scanned if the hip and lumbar spine is not accessible.

Who should undergo BMD DXA?

  • All men and women who are aged 50 or older.
  • Younger men and women who are at increased risk for broken bones caused by osteoporosis.
  • Men and women who have raised PTH (Parathyroid Hormone).
  • Men and women who have been taking corticosteroids, such as prednisolone.

What are the risks?

During a BMD scan, you are exposed to a very low dose of radiation. A BMD scan is not recommended for pregnant women. A BMD test does not cause pain.

How are results interpreted?

Results of BMD test are reported as per International Society for Clinical Densitometry (ISCD) format.

T-score

The average BMD is determined by measuring the bone density of a large group of healthy 30-year-olds (young adult reference range). BMD values are then reported as a standard deviation from the mean of this reference group.

BMD 2

Z-score

Your BMD value may also be compared to that of typical individual of same age group.

A negative (-) value means that your bones are weaker (lower bone density) than most people in your age group.

Positive (+) value means that your bones are denser and stronger than most people in your age group.

At Suburban Diagnostics, we have the High End GE LUNAR PRODIGY BMD Scanner

  1. Exceptional precision and low-dose radiation.
  2. Body composition analysis, including BMD and fat tissue mass.
  3. One Scan performs spine and Hip BMD measurements.
  4. Uncompromising quality and efficiency – 3rd generation DXA.
