This panel is designed for people receiving testosterone replacement therapy (TRT) or testosterone supplementation. It evaluates blood levels that can shift during treatment, including testosterone itself and markers that may be affected by hormone therapy such as estradiol, prostate-specific antigen, red blood cell measures, cholesterol, and liver enzymes. Monitoring these values helps a healthcare provider assess how treatment is affecting the body and whether adjustments are appropriate. The panel is not a diagnosis and does not provide dosing guidance; it supplies measurements that a qualified provider interprets alongside symptoms and treatment goals.

• Total Testosterone All testosterone in the blood, both protein-bound and unbound.
• Free Testosterone The unbound, biologically active portion of testosterone.
• Estradiol A form of estrogen that can change during testosterone therapy.
• SHBG Sex hormone binding globulin, which binds sex hormones.
• PSA Prostate-specific antigen, a prostate-related marker.
• Complete Blood Count (CBC) Includes red blood cell measures that testosterone can influence.
• Lipid Panel Cholesterol and triglyceride measurements.
• ALT (Alanine Aminotransferase) A liver enzyme used to monitor liver health.
• AST (Aspartate Aminotransferase) A liver and muscle enzyme used to monitor liver health.
• FSH Follicle-stimulating hormone, which may be suppressed during therapy.
• LH Luteinizing hormone, which may be suppressed during therapy.

• People currently receiving testosterone replacement therapy
• Individuals using testosterone supplementation who are being monitored
• Those starting or adjusting a testosterone regimen
• People whose provider wants to review how therapy affects related markers

• Collection timing may be coordinated with your treatment schedule; follow your provider's instructions
• Fasting is often recommended for the lipid component
• Report all hormone products, supplements, and medications to the laboratory

Results are compared against reference ranges and reviewed as a set. Testosterone levels show whether therapy is producing the intended blood levels, while estradiol, SHBG, PSA, blood count, lipid, and liver measures flag effects that may need attention. Because values can change with dose timing and individual response, the panel is interpreted by the prescribing healthcare provider, who decides whether any change is warranted. This testing does not itself determine dosage or treatment.
