Bone age testing is a relatively routine test, and the cost of this test is usually around$70 for the whole thing if you include all the registration fees, exams, and so on. This includes about$55 for the radiographs and about$15 for the registration and consultation fees. However, this fee may fluctuate depending on the region and hospital. Radiographs of a child’s wrist bones can be used by an orthopedic surgeon to determine a child’s bone age, that is, the actual age at which a child’s bones develop, usually before the age of 10 years. If there is no obvious developmental abnormality in the body before the age of 2, as well as the developmental abnormality of height, weight, head circumference and other indexes, it is possible not to carry out the bone age test first. If there are any deformities or abnormalities in the development of limbs, the bone age test should be carried out in time, together with other blood and endocrine tests, to determine the reasons for the delay in the age of skeletal development.
