Bone density test reports are often used to reflect the strength of a patient’s bones and to detect the mineral density within the human skeleton. The BMD test report usually contains both a graph and a numerical value. The graph is a curve that indicates the patient’s bone density and the trend of the high and low values of the normal bone density range. For the numerical value, there are two categories: T-value and Z-value. T-value refers to the difference between the patient’s bone quality and that of a normal person, usually as long as the T-value is within the range of -1-1 is normal; if it is between -2.5 and -1, it indicates signs of osteoporosis or bone loss; if the T-value is below -2.5, it indicates the existence of serious osteoporosis. Z-value refers to the difference between the patient’s bone density and that of a person of the same age, under normal circumstances. If the Z-value is below -2 it means that the patient’s bone density is low compared to normal peers. The BMD test report can visually reflect whether the patient has osteoporosis and can also detect calcium deficiency. For patients with reduced bone mass or the presence of osteoporosis, it is recommended that medication be administered as prescribed by the doctor, which usually provides relief in about 3 months.
