Everything You Need to Know About a Bone Density Test

If you've ever wondered "how is a bone density test done?", or "what does a bone density test show?", you're not alone. Whether you're concerned about osteoporosis, dealing with unexplained fractures, or simply being proactive with your health, a bone density test is a powerful diagnostic tool you shouldn’t overlook.

In this guide, we’ll answer all the most common questions—from how a bone density test is done on a woman to where to get a bone density test near you. You’ll also learn why a DEXA scan (the gold standard in bone testing) gives you the clearest picture of your long-term bone health.

What Is a Bone Density Test and How Is It Done?

A bone density test, also known as a DEXA scan, measures how much calcium and other minerals are in your bones. This helps assess your risk for osteopenia or osteoporosis—conditions where bones become weak and brittle.

How is a bone density test performed?

  • You lie flat on a padded table.
  • A low-dose X-ray scanner moves over your spine, hip, or forearm.
  • The scan is completely non-invasive and takes only about six minutes.
  • You don’t need to remove your clothes (as long as they don’t have metal).
  • No injections, no discomfort.

If you're wondering “how is a bone density test done on a woman?” — the process is exactly the same as it is for men. However, women are generally screened more often due to postmenopausal risk of bone loss.

What Does a Bone Density Test Consist Of?

A bone density test involves scanning major bone areas—typically the hip, lumbar spine, and sometimes the forearm. The machine then calculates two important scores:

  • T-score: Compares your bone density to a healthy young adult.
  • Z-score: Compares your density to someone your own age, sex, and size.

These scores help determine whether your bones are:

  • Normal
  • Osteopenic
  • Osteoporotic

Still asking "what does bone density test show?" It shows your risk of fracture, disease progression, and bone loss over time.

What Are 3 Things a Bone Density Test Can Identify?

  1. Osteopenia or Osteoporosis Diagnosis
  2. A DEXA scan reveals whether your bones are thinning or at high risk of breaking.
  3. Fracture Risk
  4. Combined with age, sex, and lifestyle, your scan results help estimate your 10-year fracture risk.
  5. Response to Treatment or Lifestyle Changes
  6. Whether you’re taking medication or using natural interventions, a scan shows how well it’s working.

How to Read a Bone Density Test

  • T-score above -1: Normal
  • T-score between -1 and -2.5: Osteopenia
  • T-score below -2.5: Osteoporosis

Doctors may also assess your FRAX score for a comprehensive fracture risk profile.
