Get a Clear Indication of Problem through Bone Density T Score
There are several methods available to measure bone density in which dual energy x-ray absorptiometry is being widely used. This method can easily determine the efficiency in the recent clinical trials required to characterize the fracture risk in large epidemiological treatment studies. Though there are some older methods that they do not predict hip fractures. Bone density T score and Z score cater the better predictability for the treatment.
T score gives a comparison in the study of bone mineral density to that of young people of the same sex and ethnicity. Furthermore, people over 50 can predict better the risk of future fracture. According to the criteria of World Health Organization, the norms are defined as T-score of -1.0 or higher refer normal. Osteopenia is defined as less than -1.0 and greater than -2.5, and Osteoporosis as -2.5 or lower, meaning a bone density that is two and a half standard deviations for around 30 year old woman.
There are different T-scores that depend on the different age group of the people. There is another score as Z-score that refers to the number of standard deviations below an average person of the same age. It could be limited to the patient of same age, weight and gender. Moreover, the DXA test results are compared to the ideal or peak bone mineral density of the healthy persons. A score of 0 refers that your bone mineral density is equal to the norm for a healthy person. The more standard deviations below 0 indicate the negative number that means your BMD renders higher your risk of fracture. Bone density t score between +1 and -1 is considered normal or healthy. Furthermore, deviation between -1 and -2.5 refers to the low bone mass, and T-score of -2.5 or lower represents to the osteoporosis.
