Total testosterone measures how much testosterone is present in the blood and can identify clearly low levels.

Free testosterone and the Free Androgen Index provide additional detail about how testosterone is carried and made available in the body. Clinicians may use this extra information to better understand results when making individual decisions.
Testosterone is often called the "male hormone" — but it's far more than that. It affects energy, mood, muscle mass, bone density, libido, and overall quality of life.
After age 30, testosterone levels naturally decline by about 1-2% per year. But lifestyle factors like poor diet, lack of exercise, stress, and sleep issues can accelerate this decline significantly.
1 in 4 men over 30 have testosterone levels below the normal range — many without knowing it. Symptoms like fatigue, weight gain, low mood, and reduced libido are often dismissed as "just getting older."
