The price of a bone age film is usually around 80~150 dollars, depending on the region, the level of the hospital, the clarity of the filming instrument and the model. Bone age film refers to the observation of bone age of growing children through imaging. Generally, the orthopedic film of the left wrist joint is used to determine the bone age of the metacarpal, phalanges, and carpal bones, and then to determine whether the bone age of the child is in accordance with the actual age, and if necessary, intervention is needed to prevent the emergence of dwarfism. Generally speaking, bone age determination is done by X-ray, and the price is usually around 80~150 dollars, which is not a definite price. The price may be lower if taken at a hospital of less than tertiary level. In addition, if the hospital uses different types of instruments, the price may also vary. It is recommended to go to a regular hospital to take the bone age film and have a professional doctor to judge the bone age situation.
