The TRT Starting Panel provides all the baseline labs your provider needs before initiating testosterone replacement therapy. It establishes pre-treatment levels for testosterone (total and free), SHBG, and estradiol — the key hormones that will change on therapy. LH and FSH document pituitary function before suppression. PSA provides a baseline for prostate monitoring. CBC is essential since testosterone can increase red blood cell production (polycythemia risk). CMP, lipid panel, and HbA1c establish metabolic and cardiovascular baselines. Prolactin rules out pituitary causes of low testosterone. Thyroid panel and vitamin D round out the assessment since both affect testosterone production and overall wellbeing.
Pre-TRT baseline: Total + Free Testosterone, SHBG, Estradiol, LH, FSH, Prolactin, PSA, CBC, CMP, Lipid Panel, TSH, Vitamin D. Establishes the diagnosis, identifies cause (primary vs secondary), and screens for contraindications.
Men considering testosterone replacement therapy — required by most TRT clinics and good medical practice before initiating treatment. Confirms the diagnosis, rules out pituitary tumors, and establishes baselines for safety monitoring.
