IntroLab provides you with the opportunity to undergo testing for free testosterone, an important hormone for both men and women.

What is free testosterone?

Testosterone, a crucial male hormone that also plays a vital role in women, exists in two forms within the human body: bound and free. Most of the testosterone is “bound” to proteins known as albumin and sex hormone-binding globulin (SHBG). In contrast, free testosterone is not bound to proteins and can circulate freely in the bloodstream. Although free testosterone represents only about 2-3% of the total testosterone, this “free” portion is biologically active and can interact freely with receptors in the body, resulting in various physiological effects. While free and bound testosterone are the same hormone, they differ in terms of their availability for interaction with the body. This availability can impact various physiological functions and may lead to different symptoms when levels are abnormal.

When is free testosterone measured?

Testing for testosterone levels is conducted for various reasons, including:

  • In men displaying signs of hormonal imbalance. Decreased levels of this hormone can result in issues like reduced libido, erectile dysfunction, testicular shrinkage, and breast enlargement.
  • In boys experiencing abnormal puberty development. During puberty, testosterone levels naturally rise, leading to the development of secondary sexual characteristics such as facial hair growth, voice deepening, and muscle development. If a doctor suspects a child is entering puberty too early or too late, they may recommend testosterone testing.
  • To monitor the effectiveness of testosterone therapy. Men undergoing testosterone replacement therapy often undergo regular tests to assess therapy effectiveness and determine if dosage adjustments are needed.
  • In women exhibiting masculinization. While testosterone is primarily a male hormone, women also have it in smaller amounts. Elevated testosterone levels in women can lead to the development of male secondary sexual characteristics, such as a deepened voice, increased body hair, acne, and menstrual irregularities. Testing for testosterone can be valuable in identifying these conditions.

Interpreting the results

Elevated levels of free testosterone can indicate various health issues, including polycystic ovaries in women, tumors that produce testosterone, or the use of anabolic steroids.

Reduced levels of free testosterone may indicate:

  • Hypogonadism (a condition in which the body doesn’t produce enough sex hormones)
  • Issues with the pituitary gland
  • Or they may be a result of obesity or a chronic illness

Only a doctor or hormone specialist can accurately interpret the test results. They will consider individual symptoms, medical history, and other tests to make a precise diagnosis. The results of the free testosterone test should always be assessed in the context of the overall clinical picture.
