So, a lower lh is indicative of secondary hypogonadism (pituitary or hypothalamus) The igf-1 being lower like that would indicate a possible gh deficiency but you would need a glucagon or ITT stim to find out. Besides the full iron panel, if it were me, I would want a reverse t3 checked as well as am cortisol, acth serum, and a mri. I cannot remember if dhea-s , or any thing else was tested . Other things like serum sodium/potasium and chloride serum would give you some more ideas as to your condition. Obviously the tsh elevated is a issue, however I would be getting both antibodies tested for Hashimoto's if it were me. Free t3, (the active thyroid hormone) the average healthy person really does have a free t3 in the upper portion of the range (3.5 to 3.8) range of 2 to 4.2-so not anything in the range is all good as they test healthy and sick people in the hospital to get that range like that-just some thing to consider. Sorry to write so much
