Your Bloodwork Is Only Part of the Story: What a DEXA Scan Adds

Bloodwork can answer important health questions, but it cannot directly measure everything. A patient can know cholesterol, glucose, blood counts, and other laboratory values and still have questions about bone mineral density or body composition.

That is where DEXA can add a different kind of information. At Houston Concierge Medicine, Dr. Greg Burzynski can help determine when a DEXA scan is useful and how the results fit with the patient's broader health picture.

What Does DEXA Measure?

Dual-energy X-ray absorptiometry, commonly called DXA or DEXA, is widely used for bone mineral density assessment. Depending on the scan protocol and purpose, DXA can also provide body composition information such as lean mass and fat mass.

The International Society for Clinical Densitometry publishes standards for bone mineral density testing and body composition applications. The key point for patients is that DEXA provides structural and composition information that a blood test does not directly provide.

DEXA and Bloodwork Answer Different Questions

It is tempting to think of one test as more advanced than another. A better way to think about diagnostics is that different tests answer different questions.

Laboratory testing may help evaluate metabolic, hormonal, nutritional, or other physiologic concerns. DEXA may provide information about bone density or body composition. Neither replaces the other, and neither replaces the medical history and clinical evaluation that come with ongoing primary care.

Who May Need Bone Density Testing?

Bone mineral density testing is recommended for certain populations based on age and risk factors. The ISCD's 2023 adult official positions include women age 65 and older, men age 70 and older, and younger adults with specific risk factors such as prior fragility fracture, low body weight, high-risk medication use, or conditions associated with bone loss.

Individual recommendations can differ, so age alone should not be used as a self-screening rule. Dr. Greg Burzynski can review risk factors and determine whether bone density assessment is appropriate.

Body Composition Can Add Context Beyond the Scale

A bathroom scale shows total body weight. It does not distinguish how much of that weight is lean tissue versus fat mass. For patients working on health, fitness, or medically supervised weight-management goals, body composition can provide a different baseline.

The goal is not to collect more numbers for their own sake. It is to use measurements that answer a relevant question and then interpret those measurements in context.

Connect the Data With the Patient

More testing is not automatically better care. Better-connected information can be. At Houston Concierge Medicine, a DEXA scan is included once a year in the Gold concierge membership and twice a year in Platinum, alongside lab testing, so body composition and bloodwork can be reviewed together over time.

If you would like to learn whether DEXA bone density or body composition testing may be appropriate for your goals, contact Houston Concierge Medicine to discuss DEXA testing and interpretation with Dr. Greg Burzynski.
