What to Expect When Getting a Bone & Body Composition Test

February 11, 2025

If you're considering a bone and body composition test, you might be wondering what it involves, why it's important, and what the results can tell you about your health. Whether you're an athlete, managing osteoporosis risk, or simply looking to understand your body better, this test provides valuable insights into bone density, muscle mass, fat percentage, and overall body composition.

What Is a Bone & Body Composition Test?

A bone and body composition test is typically performed using a Dual-Energy X-ray Absorptiometry (DXA or DEXA) scan. This advanced imaging technology measures:

Bone mineral density (BMD) – Assesses your risk for osteoporosis and fractures.

Body fat percentage – Determines how much of your body weight comes from fat versus lean mass.

Lean muscle mass – Measures muscle distribution throughout your body.

Fat distribution – Identifies where fat is stored, including visceral fat around organs.

DXA scans are quick, painless, and non-invasive, making them a highly effective way to assess overall body health.

Why Might You Need This Test?

A bone and body composition test can be beneficial for many reasons, including:

Osteoporosis screening – Helps detect early signs of low bone density.

Weight loss or fitness tracking – Provides a more detailed picture than a standard scale.

Athletic performance – Optimizes muscle mass and fat levels for peak performance.

Health risk assessment – Identifies excess visceral fat, linked to heart disease and diabetes.

Monitoring body changes – Tracks progress from lifestyle changes, medical treatments, or training programs.

How to Prepare for the Test

The DXA scan requires minimal preparation, but following these steps can help ensure accurate results:

Wear comfortable, loose-fitting clothing (avoid metal zippers or buttons).

Avoid calcium supplements for at least 24 hours before the test, as they can affect bone density readings.

Stay hydrated, but avoid large meals right before the test.

Skip intense workouts on the day of the scan, as exercise can temporarily alter body composition readings.

What Happens During the Test?

A DXA scan is quick and straightforward, typically taking 10–20 minutes. Here’s what to expect:

Lying on a Table – You’ll lie flat on a padded table while the scanning arm moves over your body.

Minimal Radiation Exposure – The test uses low-dose X-rays, significantly lower than a standard X-ray.

Stay Still – The scan is painless, but staying still is essential for accurate measurements.

Quick Results – Your data is usually processed immediately, and your healthcare provider will review the findings with you.

Understanding Your Results

Your results will include:

Bone Mineral Density (BMD) – Measured in g/cm², compared to a reference population to assess bone health.

Body Fat Percentage – Helps determine healthy fat levels based on age, gender, and fitness level.

Lean Mass & Muscle Balance – Identifies muscle distribution and possible imbalances.

Visceral Fat Measurement – Higher levels can indicate increased health risks.

A healthcare provider will help you interpret your results and what they mean for your overall health.

What to Do After the Test

Once you have your results, you can use them to adjust your diet and exercise routine, take steps to improve bone health with calcium and vitamin D, or consult a doctor if any concerns arise. If you're tracking changes over time, scheduling follow-up tests can help measure progress. A bone and body composition test is a powerful tool for understanding your health beyond just weight, offering valuable insights in a quick, painless, and highly informative way. If you're interested, talk to your doctor or a DXA scan provider to see if it's right for you.
