Disease description:

My child is much shorter than peers of the same age. I'd like to take him to the hospital for an evaluation. Does checking for short stature require blood tests? Which department should we visit at the hospital?

Children who are not growing tall enough generally need blood tests and should visit the endocrinology department or pediatrics department at a hospital for evaluation and treatment. It is recommended to visit the hospital's endocrinology or pediatric department on an empty stomach. The underlying cause can be identified through tests including complete blood count, urinalysis, trace elements, comprehensive biochemical panel, growth hormone, sex hormones, bone age assessment via X-ray, and alkaline phosphatase levels. Treatment should then be directed according to the specific cause identified.
