What Does Your DEXA Score Actually Mean?

Your DEXA Report May Look More Complicated Than It Is
If you have ever received a DEXA report, you may have seen terms such as:
• T-score
• Z-score
• Bone mineral density
• Osteopenia
• Osteoporosis
These numbers can be confusing. Understanding what they mean can make it easier to have a productive conversation about your bone health.
What Is a T-Score?
A T-score compares your bone mineral density with that of a healthy young adult reference population.
For postmenopausal women and men age 50 and older, T-scores are commonly used when classifying bone density.
What Is a Z-Score?
A Z-score compares your bone density with people of similar age and sex.
Z-scores are particularly useful in younger individuals and certain clinical situations.
Osteopenia and Osteoporosis
Bone density classifications are commonly described as:
• Normal bone density
• Osteopenia
• Osteoporosis
But a diagnosis and treatment decision should not necessarily be based on one number alone.
Why Your T-Score Isn’t the Whole Story
A patient’s previous fracture history may be extremely important.
So may:
• Age
• Family history
• Medication use
• Medical conditions
• Fall risk
• Other clinical factors
This is why two people with the same T-score may receive different recommendations.
Don’t Panic About a Single Number
A DEXA score is a measurement—not a prediction of exactly what will happen to you. The goal is to combine the measurement with the rest of your health information to understand your individual fracture risk.
Key Takeaways
• T-scores compare bone density with a young adult reference.
• Z-scores compare bone density with age-matched individuals.
• Lower scores generally indicate lower bone density.
• DEXA results should be interpreted in context.
• Fracture history and other risk factors matter.
