Build the lab conversation around the decision.
More testing is not automatically better. Choose the question you are trying to answer, then take a concise core-and-conditional checklist to a qualified clinician who can tailor and interpret it.
Choose relevant goals. The result separates broadly useful foundation markers from conditional tests that depend on symptoms, history, age, medication, and clinical judgment.
Why testosterone testing starts with diagnosis—not optimization
Endocrine Society guidance recommends diagnosing hypogonadism only when compatible signs or symptoms occur with unequivocally and consistently low testosterone, confirmed with a repeat morning measurement. It also recommends evaluation of the cause rather than treating an isolated number.
This tool reflects that sequence. It does not interpret your result, define treatment eligibility, or tell you to order every conditional marker.
