Updated Labs: Low Vit D/B12/Platelets questions

I was thinking thyroid would be off because I have EXTREME cold intolerance, Im capable of getting hot like anybody else (although Im much more tolerant than most), but my threshold for even slightly cool temps is awful, drives my friends insane. It was 72 the other day and I had the seat heater on in my friend's truck. It's 70's in the house with ac on and my hands and feet are going numb.

I had considered ordering the antibody panel but was hoping the basic thyroid stuff would point me in the right direction. My big fear is spending more and more and not figuring anything out, but that's always my fear with medical, you dont know until you know, and you dont get refunds when you dont learn anything new, it's a slipperly slope for me, just due to past experiences.

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
