The short answer
Total Testosterone is measured with a standard blood draw; no fasting is needed. A typical reference range is 264 – 916 ng/dL (male, age 18+; more bands below). At TestWell it's $33.99 all-in as Testosterone, Total, results in 1–3 business days, drawn at Quest or Labcorp. An out-of-range result is a prompt to look closer, not a diagnosis.

How often should you retest Total Testosterone?
One low reading isn't a diagnosis: the Endocrine Society asks for an unequivocally low total testosterone on at least two separate morning samples (ideally fasting, before 10 AM) before calling it hypogonadism. Men on testosterone therapy typically have levels rechecked 3–6 months after starting, then annually.
