Testosterone (Total) – Testosterone is the primary male sex hormone (also present in women), influencing libido, muscle, mood, and energy.
What Testosterone measures
Testosterone measures total testosterone in your blood – the standard starting point for assessing low or high levels.
Typical ranges
Adult male reference ranges are roughly 300-1,000 ng/dL, varying by lab and age; female ranges are much lower. Reference ranges differ between laboratories and by age and sex, so always read your result against the range printed on your own report.
What high results can mean
In men, can relate to supplementation; in women, can relate to PCOS or other conditions.
What low results can mean
In men, can cause fatigue, low libido, and mood changes (low testosterone).
How the test is done
A blood sample, ideally drawn in the morning when levels peak. At-home collection works well for this marker when the sample is processed by a certified lab.
