Bone density check cannot be compared
Bone density examination is a way to determine the health status of bone. It can identify osteoporosis, prevent risk of fracture, and monitor the treatment effect of osteoporosis. Bone density measurement can be measured in multiple parts of the human body, such as hips, spine, wrists, heels, etc. A standard deviation (SD) between the measurement results of the bone density and the healthy young people data. According to the World Health Organization diagnostic standards, the definition of osteoporosis is based on the level of bone density. Based on the comparison of young people’s bone density.
If the results of the bone density measurement are within the “standard” range, the bone density is considered to be normal, and a person with a standard difference between 25 standard deviations lower than the normal average bone density peak value is called patients with osteoporosis. These people eventually fracture more than 95%of people.
Normal: The bone density is within 1 standard deviation of the average value of young people (+1 ~ -1SD)
Low bone density: Bone density is lower than the average value of young people by 1 ~ 2.5 standard deviations (-1 ~ -2.5sd)
Osteoporosis: Bone density is lower than the average of 2.5 standard deviations (below -2.5sd)

The diagnosis of osteoporosis is based on the comparison of the average bone density of patients and normal people. Therefore, the bone density check can only be compared vertically, and the horizontal comparison is not reliable. Do not hold your own bone density check form with the bone density value of others.
Most bone density instruments now have the advantages of high accuracy, simple operation, and non -damage. Patients do not need special preparations before examination. There is no pain during the measurement. CT and X -ray examinations are similar. The measurement results are processed by the computer. Generally speaking, the bone density check is performed by one part and one part, and the test results also reflect the bone density value of a certain part, and the whole body situation needs to be comprehensively evaluated.
