Testosterone (Total)

Total Testosterone measures the overall amount of testosterone (bound and unbound) in the blood. It's the primary male sex hormone, crucial for muscle mass, bone density, libido, energy, and mood. Levels decline with age. Low levels (hypogonadism) can cause various symptoms. Optimal ranges for symptom relief and well-being are often targeted in the mid-to-upper end of the standard reference range, considering Free Testosterone as well. Important Notes:

1. Testosterone levels naturally vary by age.
2. Testosterone levels are typically highest in the morning (e.g., 8-10 AM), and reference ranges are usually based on morning samples. Levels measured later in the day may be lower.
3. Consider measuring Free Testosterone, SHBG, and Albumin for a more complete picture, especially if Total T is borderline or symptoms are present despite normal Total T.

Total Testosterone measures the overall amount of testosterone (bound and unbound) in the blood. It plays a role in sexual desire/arousal, energy, mood, and helps support muscle and bone. Levels vary across the menstrual cycle and tend to decline with age. Elevated levels (hyperandrogenism) are more commonly the clinical issue in women and should be evaluated promptly.
