What is the T-score range for osteoporosis?
A T-score of 1 to 2.5 SD below the young adult mean (-1 to -2.5 SD) indicates low bone mass. A T-score of 2.5 SD or more below the young adult mean (more than -2.5 SD) indicates the presence of osteoporosis.
What is a normal T and Z score for bone density?
As shown in the table below, a T-score between +1 and −1 is considered normal or healthy. A T-score between −1 and −2.5 indicates that you have low bone mass, although not low enough to be diagnosed with osteoporosis. A T-score of −2.5 or lower indicates that you have osteoporosis.
What are the guidelines for a bone density test?
NOF recommends that you have a bone density test if:
- you are a woman age 65 or older.
- you are a man age 70 or older.
- you break a bone after age 50.
- you are a woman of menopausal age with risk factors.
- you are a postmenopausal woman under age 65 with risk factors.
- you are a man age 50-69 with risk factors.
What is the gold standard for osteoporosis?
In the absence of a fragility fracture, BMD assessment by dual-energy x-ray absorptiometry (DXA) is the gold standard to diagnose osteoporosis, according to the classification of World Health Organization (WHO) .
Why is DEXA the gold standard for osteoporosis?
Bone densitometry is the gold standard for diagnosing osteoporosis, and dual-energy x-ray absorptiometry (DXA) is the preferred technology for measurement. Because of its ease of use, low radiation exposure, and ability to measure BMD at both the hip and spine, DXA is the most commonly used technique to measure BMD.
