Understanding Testosterone Total
What is Testosterone Total?
The Testosterone Total test is a blood test that measures the amount of testosterone. It is primarily a male sex hormone, but found in both men and women. This test helps determine hormonal balance and detects conditions like low testosterone, infertility, or hormonal disorders.
Testosterone is produced by the testicles in men and the ovaries in women. It helps develop secondary sexual characteristics like facial hair and a deeper voice. It also helps build muscles and keep bones strong, which are important for strength and health. Testosterone affects mood, energy, and sex drive, and it plays a role in having healthy reproductive function. Even though it is mainly a male hormone, women also make small amounts, and it helps with muscle growth and the health of reproductive organs.
The Testosterone Total test helps assess male infertility and identify hormonal imbalances. It is done in males experiencing symptoms such as low libido, fatigue, mood disturbances, and muscle weakness. This test also helps in monitoring treatment effectiveness, such as hormone replacement therapy. In females, it helps in detecting conditions such as menstrual irregularities and excess facial hair.
Usually, no special preparation is required for this test. Eat and drink as per the daily routine. However, it should be noted that testosterone levels are the highest during the early morning and lowest in the evening, and they increase with exercise and decrease with age.
Lab test results may vary across laboratories. Interpretation of the test results requires expert guidance. Therefore, do not self-medicate and talk to the doctor to understand the test results correctly.

What does Testosterone Total measure?
The Testosterone Total test measures the level of testosterone hormone available in the blood. This includes two forms of testosterone: free testosterone and bound testosterone. Bound testosterone is attached to proteins, mainly to sex hormone-binding globulin (SHBG) and albumin. It cannot enter the body's cells or directly affect tissues and organs. Instead, it acts as a store of testosterone in the blood and can be released when the body needs it. Free testosterone is not attached to any proteins and is the active form. It can easily transport to various tissues, and affects key functions like sex drive, muscle growth, bone strength, and energy levels.
