WHAT TESTS DO PEOPLE RECOMMEND ON HERE!! PLEASE I NEED HELP AND NEED TO KNOW WHAT I SHOULD BE SPENDING MONEY ON AND NOT WASTING IT ON. THANKS

Which of these should I go for?

Serum Testosterone?(Since my levels were crazy in saliva test)
Do males do Estrogen and oestrodial tests?
Vitamin B12 (may contribute to depression??
Serum Folate (as Above)
Ferritin (Might have something to do with thyroid)
Iron/TIBC ??
Serum Insulin (Sugar levels?)
Liver Function Test (Not sure?)
Urea And Electrolytes (may show potassium levels and others)

Serum DHEAs (Might see if elevated high since my saliva was excessive?)
Serum Cortisol (is this worth doing?)
(Had the saliva tests done so is it worth doing blood tests for these cortisol and Dheas?)
Adrenal Antibodies ??
IGF-1 Insulin ??
Candida Antibodies (Might show candida but is it accurate and maybe I coudl just do the diet and not worry about testing?)
HomoCysteine (Not sure)
Blood Allergy testing (150 Foods) (its quite expensive but shows intolerances too which is good.


Im at a loss on what tests I should do.

At the moment I feel constant pressure or tension in chest or stomach and try to relax the muscles(they shake alot too) and notice my heart palpitations or pulse in neck when I lie down(could be mental based?)

I also feel slightly flushed and cant concentrate.
