###Human: I want to test myself for HGH deficiency. Can you tell me how I should proceed? ###Assistant: Hi. You need to check IGF1 level (insulin-like growth factor 1), liver function and kidney function tests and hemoglobin level. Also please take an x-ray of your left elbow and left knee joint AP view (anteroposterior view) to assess the bone age, and to check whether ends of the bones still have room enough to allow growth or they have fused. Kindly mention your height and your parents' height. You may also send your latest thyroid reports.
