Age for women at which BMD testing is indicated without caveat - ANSWER: 75
Four risk factors that are indicators for BMD testing in post-menopausal women who
are younger than 65, in women who are currently in the transition to menopause,
and in med who are younger than 70: - ANSWER: 1) low body weight
2) prior fracture
3) high risk medication use
4) disease/condition associated with bone loss
Age at which BMD testing is indicated for men: - ANSWER: 70 and older.
What type of fracture is an indication for BMD testing in any adult? A fragility
fracture
Two generic indications for BMD testing: - ANSWER: 1) Anyone being considered for
pharmacologic therapy.
2)Anyone not receiving therapy in whom evidence of bone loss would lead to
treatment.
One obvious indication for BMD testing: - ANSWER: Anyone being treated, to
monitor treatment effect.
A uniform Caucasian female normative database should be used as the reference for
which cohorts? - ANSWER: 1) Women of ALL ethnic groups
2) Men of ALL ethnic groups
What reference standard should manufacturers use for femoral neck and total hip T-
scores? - ANSWER: NHANES III data
What reference standard should manufacturers use for the lumbar spine T-scores? -
ANSWER: The manufacturer's own database
Should local reference data be used to calculate T-scores? - ANSWER: No.
Can local reference data be used to calculate Z-scores? - ANSWER: Yes, if local
reference data is available.
What is the WHO international reference standard for diagnosing osteoporosis? -
ANSWER: A T-score of -2.5 or less at the femoral neck, which is calculated using the
uniform female, white, age 20-29 years, NHANES III database.
, A T-score of -2.5 or less at any of which three sites earns the diagnosis of
osteoporosis in postmenopausal women and men aged 50 and older? - ANSWER: 1)
Lumbar spine
2) Total hip
3) Femoral neck
(In certain circumstances, the 33% radius may be utilized.)

2)Hyperparathyroidism
3)Very obese patients who are over the weight limit for DXA table
Which vertebrae are used to measure spine BMD? - ANSWER: PA L1-L4
Which vertebrae should be excluded from evaluation? - ANSWER: Those that are
affected by local structural change or artifact.
Those that are clearly abnormal and non-assessable within the resolution of the
system
How many vertebrae must be used for diagnostic classification? - ANSWER: At least
two, but ideally all four will be used.
What if only one evaluable vertebrae remains and has low BMD, how should
diagnosis be made? - ANSWER: Diagnosis must be based on a different VALID
skeletal site.
If there is more than a ______ T-score difference between the vertebrae in question
and adjacent vertebrae, exclude the vertebrae in question from analysis. - ANSWER:
1.0
When vertebrae are excluded, what is used to derive the T-score? - ANSWER: the
BMD of the remaining vertebrae
