INITIAL LABWORK
Following a good Medical History, which laboratory assays should be run as part of your initial hypogonadism workup? Following is my list, but certainly other specialists in this area run expanded or attenuated panels, per their experience and expertise. Of note, there are several other tests which should be included to complete the true comprehensive Anti-Aging Medicine workup (i.e. homocysteine, fasting insulin, comprehensive thyroid study, etc.), as this chapter is concerned solely with administering TRT. And as always, the panel is tailored to the individual patient. Here they are:
• Total Testosterone
• Bioavailable Testosterone (AKA “Free and Loosely Bound”)
• Free Testosterone (if Bioavailable T is unavailable)
• DHT
• Estradiol (specify the Extraction Method, or “sensitive” assay for males)
• LH
• FSH
• Prolactin
• Cortisol
• Thyroid Panel
• CBC
• Comprehensive Metabolic Panel
• Lipid Profile
• PSA (if over 40)
• IGF-1 (if HGH therapy is being considered)
