Testosterone, Total
Panel: Hormone Tests · All hormones tests
Typical adult reference range
| Conventional units | Male 300–1,000; Female 15–70 ng/dL |
| SI units | Male 10.4–34.7; Female 0.5–2.4 nmol/L |
Ranges vary between laboratories and methods — compare your result with the range printed on your own report.
What a high or low result can mean
High testosterone, total: high values can be seen in androgen-producing tumors and, in women, in polycystic ovary syndrome.
Low testosterone, total: low values may occur in hypogonadism, pituitary disorders, and chronic illness.
These are associations, not a diagnosis: the same result can have several causes, and your clinician interprets it with the rest of your results and history.
Good to know
Levels are highest in the morning; morning samples are standard in men.

Please note: Reference ranges vary between laboratories, and between the methods and instruments they use — the range printed on your own report is the one your result should be compared with. A result outside the range is not by itself a diagnosis, and a result inside it does not rule out illness. These pages are an educational summary, not medical advice: always discuss your results with the clinician who ordered them, who can interpret them in the context of your health and history.
