In our last post I promised this next post would deal with how osteoporosis is diagnosed. Unfortunately, for many people the diagnosis comes after a bone fracture or break. That takes us back to the fact that early diagnosis is important. If your doctor recommends a bone density test, have it done. Again, I stress the fact that if you don't have a primary care doctor, you should get one, have regular checkups and follow the doctor's advice. Bone density testing is important for early diagnosis of osteoporosis and osteopenia. (Osteopenia is a lower-than-average bone density but not as severe as osteoporosis.)
As I stated in the last posting, a bone mineral density test is very simple and painless. The healthcare provider will usually order a test simply known to the patient as a bone density test. The test is called central dual-energy X-ray absorptiometry (DXA or DEXA scan) to measure bone mineral density. The most typically scanned areas are the hip and spine. The test results are known as T-scores. Here is how the T-scores are given and what they mean.
A T-score of -1 or higher means normal bone density
A T-score of Between 1- and -2.5 means low bone density/osteopenia
A T-score of -2.5 or lower means osteoporosis
The United States Preventive Services Task Force recommends osteoporosis (bone density test) screening for women who are 65 and older. They also recommend it for women under age 65 who have risk factors for osteoporosis.
