OK...blood work....i've been searching and asking for days now trying to figure out what blood tests to do but i can't get an answer. The following is the standard recommended blood test:
Total Testosterone
Bioavailable Testosterone
Free Testosterone (if Bioavailable T is not available)
DHT
Estradiol
LH
FSH
Prolactin
Cortisol
Thyroid Panel
CBC
Comprehensive Metabolic Panel
Lipid Profile
IGF-1
What i would like to know is...which of the above is "not necessary" to take to determine the cause of low test? Therefore, what are the "important" tests to do or which blood tests are irrelevant to TRT?
