Testosterone, Total

Total Testosterone measures the overall amount of testosterone circulating in the bloodstream, including both bound and free (active) hormone. Testosterone plays a central role in muscle mass, energy, libido, mood, bone density, and overall metabolic health in both men and women.

Total Testosterone testing helps assess:
• Low energy or fatigue
• Decreased libido
• Muscle mass and strength concerns
• Mood changes
• Hormone balance in men and women
• Monitoring hormone therapy

Reference Range (General Guidance):
Reference ranges vary by age and sex.
Adult men typically have significantly higher levels than women.
Levels are generally highest in the morning.

What Your Results May Mean
• Elevated Testosterone: May be associated with hormone therapy, PCOS, adrenal conditions, or other endocrine disorders.
• Low Testosterone: May suggest hypogonadism, pituitary dysfunction, aging-related decline, or other hormonal imbalances.

Total testosterone is often interpreted alongside Free Testosterone and SHBG for a more complete evaluation.
