The Usefulness of Bone Density Charts

In medical terminology, bone density describes the quantity of matter per square centimeter of bones. The measurement of bone density becomes crucial after a certain age. Moreover, the information provided by the test is useful to your doctor because it helps in deciding the treatment options available to you. Generally, a DXA test is utilized for measurement of bone density.

The results of bone density tests are normally scored by two measures, Z-score and T-score. These scores indicate the deviation of an individual’s bone density from the standard. While a negative score indicates a lower bone density, a positive score indicates a higher bone density. Therefore, bone density charts indicate the deviation your bone density from the established standards.

The T-score helps in comparing the bone density of a patient with that of a thirty-year-old adult of same ethnicity and sex. Moreover, the value of your T-score is utilized for post-menopausal women as well as men above the age of 50 years since it is utilized for predicting the risk of future fractures. The disease of an individual is decided by the value of his/her T-score. An individual with a T-score in the range of -2.5 to -1 is suffering from osteopenia. Likewise, Osteoporosis is described as -2.5 or lower
Bone density charts are also prepared for indicating the Z-score of an individual. The Z-score shows the number of standard deviations that are higher than or lower than the mean for the age, ethnicity and sex of the patient. Moreover, the Z-score could be utilized for deciding whether the causal disease or condition leads to bone loss.
