In order to receive a proper diagnosis and then a prescription for a growth hormone deficiency, simple blood tests are needed. The typical blood tests ordered by the physician include, but not limited to, a CMP, CBC, IGF-1, Thyroid Panel, Lipids, Testosterone Panel, and PSA (male). Specifically, the IGF-1 (Insulin-like Growth Factor 1) panel is required to help the physician determine your initial and continuing HGH therapy dose. The physician will request additional labs, if necessary, to modify your HGH treatment 6 to 8 weeks after beginning and every 6 months thereafter.
