Can anyone post a list of the most complete labs to get while on TRT so I can let my primary Dr. know since he's willing to work with me and I'm going through my insurance this time and they will cover it.
I did that follow up TRT blood work at discounted labs last test but I wan't more details including thyroid.
 
1----- Estradiol- sensitive via LC/MS test (not EIA!) [Quest Labs code 30289]
(Labcorp code: 140244) (baseline, week 6 or 8, month 6)

GOAL: 20-50 pg/mL

2 ------- Testosterone, Free, Bio/Total (LC/MS/MS) (baseline, week 6-8, month 6, then yearly)

GOAL: Total testosterone over 500 ng/mL and free T 2 percent or more of total T.

3 ------- DHEAs (baseline, month 6, month 12 (if supplementing))

4 ------- Comprehensive Metabolic Panel w/EGFR (baseline, week 6-8, month 6 and then once a year)

GOAL: Normal CBC including liver enzyme elevations under 20 percent and eGFR over 60

5 ------- CBC w/ diff/PLT (baselines, week 6-8, month 6 and then once or twice per year)

GOAL: Normal CBC

6 ------- Lipid profile (fasting sample) (baselines, month 6, then once per year unless high)

GOAL: Normal lipids

7 ------- T3, free (for those with low thyroid symptoms)

GOAL: Upper quartile free T3

8 ------- T4, free (for those with low thyroid symptoms)

Goal: Normal free T4

9 ------- Ultrasensitive TSH (baseline, month 6, yearly after that depending on value and treatment)

GOAL: TSH under 2.5

10 -------- Prostatic Specific Antigen (PSA) (Baseline before testosterone treatment, 6-8 weeks after and then yearly)

GOAL: PSA under 3

11-------- LH and FSH (for men not on testosterone yet)- Used to diagnosed primary or secondary hypogonadism. Do not waste money testing your LH and FSH if you are on testosterone since they will be undetectable.

Blood Tests Needed Before and During Testosterone Replacement Therapy
Thanks Vince. I didn’t see reverse T3 should I test that as well? Mine was pretty high at 35 About a year ago but haven’t tested thyroid since.

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.
