Labs to be done before you start TRT
-LH and FSH
-TT
-FT or bio-T
-E2
-Prolactin - optional in most cases
-DHT [sort of a waist of time and blood if your testosterone levels are low]
-PSA
-DRE: the dreaded digital rectal exam, doc gives you the finger.
Labs to be done when on TRT
-TT
-FT or bio-T
-Implications of injections VS transdermals [and injection frequency]
-E2
-Prolactin [optional and almost never on-going]
-DHT [should be checked, but perhaps not on-going]
-LH/FSH [optional and one last time -do I have cancer?]
-PSA
-DRE: the dreaded digital rectal exam [Your doc does not enjoy this either!]
Labs to never do and timing issues:
-DO NOT test E2 ultra sensitive
-DO NOT do saliva testing for T or E2 and expect any help here
-DO NOT test for free E2
-DO NOT test total estrogens
-DO NOT test PSA within 48 hours after a DRE [digital rectal (prostate) exam] or ejaculation
-DO NOT test prolactin with 48 hours of orgasm, avoid hugging puppies and babies
-DO NOT do lab work when muscles are sore from training or injury as your "liver markers" will show high levels. Those "liver tests" are really not liver specific.
-DO NOT waist time and money on tests that you cannot take any action on. Example, testing IGF-1 for growth hormone status if there is no way you could every pay for GH or actually legally qualify for GH.
-DO NOT routinely test for LH/FSH when on TRT, perhaps once to rule out certain testicular cancers and never again
-DO NOT test for serum DHEA, must test DHEA-S
-DO NOT do saliva testing for T, DHT, DHEA, pregnenolone if taking sublingual/buccal T, pregnenolone OR DHEA OR other steroid. The tests will be wrong and you do not want cross reactivity unknowns
-Testing E2&TT&FT makes also testing SHBG sort of useless.
Labs that are stupid after you start TRT
-LH/FSH
Thyroid labs [basic first line]
-TSH
-T3 no see fT3
-T4 no see fT4
-are you getting enough iodine? probably not!
