The cost of bone age measurement is approximately between $100 and $200, except in individual cases. Bone age screening is a method to find out if a child’s bones are developing to match their biological age as they grow. X-rays of the child’s left hand and wrist are usually taken and then evaluated by a doctor. The price is therefore the cost of the X-ray + the cost of the diagnostic report. Pricing varies slightly from hospital to hospital, but the overall price range is mostly between $100 and $200, with individual cases such as special care and high-end care possibly exceeding this cost range. Bone age is determined by taking X-rays of a child’s hand and wrist, and looking at the development of the left metacarpal phalanges, carpal bones, and the ossification center of the lower end of the radius and ulna based on the X-rays. The bone age test determines the biological age of the child. Bone age also provides an early understanding of a child’s growth potential and trends in sexual maturity, and can assist in the development of individualized treatment plans for children of short stature based on the results of the examination, contributing to precision medicine.
