How to use this tool
Select your sex to see the typical adult reference range for total testosterone. If you have a lab result, you may optionally enter the value to see how it sits relative to the displayed range. The tool will describe its position in plain, neutral language — it does not label any value as "low", "high", "normal", or "abnormal".
Understanding reference ranges
A reference range is the interval that includes about 95% of values measured in a healthy reference population. Being outside a reference range is context, not a diagnosis. Many factors affect hormone levels on the day of a test: time of day, recent sleep, stress, illness, and the specific assay method used. Your clinician reads your result alongside your symptoms, history, and other tests.

Frequently asked questions
What is a normal testosterone level?
Laboratory reference ranges vary by lab, testing method, and individual factors. A commonly cited adult male total testosterone reference range is approximately 300–1000 ng/dL; adult female is approximately 15–70 ng/dL. These are population reference bands, not personal diagnoses.
Does this tool diagnose low testosterone?
No. This tool shows standard reference ranges for informational context only. It does not diagnose, interpret your results, or recommend treatment. Only your clinician can interpret your specific lab report in the context of your health history.
Why do reference ranges vary between labs?
Different laboratories use different assay methods, populations for calibration, and reporting conventions. Always compare your result to the reference range printed on your own lab report, not a generic online figure.
Is this medical advice?
No. This calculator provides estimates for informational purposes only. Always consult a qualified healthcare professional before making decisions about your health.
