Dual-Energy X-Ray Absorptiometry
DXA
Description
"Dual-Energy X-Ray Absorptiometry" (DEXA) scan evaluates bone mineral density to assess your risk of fractures, osteopenia, or osteoporosis. It’s typically ordered for older adults or those with bone loss risk factors. This low-radiation scan targets the hip and spine, where bone weakness is most likely. Results are compared to normal ranges to gauge bone strength. Based on findings, doctors may suggest supplements, lifestyle changes, or medications. Regular DEXA scans support early detection and help preserve bone health.

T-Score: Not Available
Normal Range
For All Individuals:
T-Score: >-1.0 sdu
Results That Differ From The Norm (Direct and Indirect Causes)
Abnormal results may indicate:
Celiac disease (Autoimmune disorder affecting the small intestine, triggered by gluten consumption)
Chronic kidney disease
Cushing's syndrome (Excessive levels of cortisol hormone in the body, often due to prolonged exposure to high levels of cortisol)
Hyperparathyroidism (Overactivity of the parathyroid glands, leading to excessive calcium levels)

Key Reasons For Testing
Bone Density Measurement: DXA measures bone mineral density to diagnose osteoporosis and assess fracture risk.
Fracture Risk Assessment: Identifies individuals at risk of fractures due to low bone density, guiding prevention and treatment.
Monitoring Treatment: Tracks changes in bone density to evaluate the effectiveness of osteoporosis treatments.
Body Composition Analysis: Provides insights into fat mass, lean mass, and visceral fat for health evaluation.
Chronic Disease Risk: Helps assess risks of osteoporosis, cardiovascular disease, and metabolic disorders.

Important Note
Any medical procedure yielding results outside the norm may be directly or indirectly linked to the conditions outlined on this page. Various factors, including genetics, medication and supplement usage, recent illnesses, pregnancy, pre-test eating, smoking, and stress, can impact the test's outcome. Additionally, factors like false positives, false negatives, inaccurate analyses, and others can influence results.
Reference ranges, which help healthcare professionals interpret medical tests, may vary depending on age, gender, and other factors. They may also differ between laboratories due to variations in instruments and methods used. Optimal ranges are designed for preventive purposes, aiming to identify trends and potential risks early, while normal ranges reflect conventional laboratory values indicating no current disease or pathology. Your healthcare practitioner may have specific reasons for testing that deviate from the usual or may interpret results differently based on individual circumstances. Proper interpretation typically involves considering clinical findings and other diagnostic tests. Hence, it is crucial to provide your healthcare professionals with a comprehensive medical history, consult with them for result interpretation, and follow their guidance for potential re-testing or additional diagnostics.
