Understanding the process
A thorough testosterone evaluation goes beyond a single blood draw. Providers start with a physical exam and questions about your medical history, medications and symptoms. They usually order two morning total testosterone tests because levels vary throughout the day. Additional tests include luteinizing hormone (LH) to check pituitary function and prolactin to rule out pituitary tumors.
Functional additions
Functional medicine adds tests for free testosterone, SHBG, estradiol, DHEA‑S, cortisol patterns, thyroid hormones, vitamin D, prolactin, and metabolic panels. Reviewing these markers together helps practitioners distinguish between primary endocrine disorders and issues driven by stress, sleep disruption or metabolic dysfunction.
Real‑world visit: what to expect
During his evaluation, Kevin, 45, provided a detailed health history and underwent a physical exam. He had two morning blood draws for total testosterone and additional labs for free testosterone, SHBG, LH, FSH, estradiol, cortisol and thyroid. He also completed a sleep questionnaire and kept a food log. This comprehensive picture allowed his clinician to tailor a plan that addressed vitamin deficiencies, stress and hormone levels.
Conventional vs functional testing
Conventional testing typically includes total testosterone, LH and prolactin. Functional testing expands the panel to include adrenal, thyroid and metabolic markers. Clinicians may also ask about sleep, stress and diet. When necessary, they collaborate with clinics that specialize in testosterone replacement therapy to interpret results and plan treatment.
Key message
A comprehensive evaluation examines many pieces of the hormone puzzle. Understanding what tests are available empowers you to ask for a full assessment rather than a single number.
