The Free Androgen Index (FAI) test is a valuable diagnostic tool used to measure the levels of free testosterone and sex hormone-binding globulin (SHBG) in the bloodstream. The blood test for testosterone helps assess androgen levels and their potential impact on a person's health. By evaluating the balance between free testosterone and SHBG, medical professionals can identify hormonal imbalances that may contribute to various conditions.

The symptoms of testosterone and SHBG-related hormonal imbalances include:

  • Decreased libido and sexual dysfunction
  • Fatigue and reduced energy levels
  • Mood swings and irritability
  • Muscle weakness and loss of muscle mass
  • Acne breakouts and oily skin
  • Hair loss or excessive hair growth
  • Weight gain or difficulty losing weight
  • Changes in menstrual cycle in women

To perform the blood test for testosterone, a small blood sample is required. A healthcare professional will clean the patient's arm with an antiseptic and then insert a needle into a vein to draw the blood. The blood sample is then sent to the laboratory for analysis. This procedure is relatively quick and minimally invasive.

In the laboratory, the blood sample is analyzed to measure the levels of free testosterone and SHBG. The Free Androgen Index (FAI) is calculated by dividing the total testosterone concentration by the SHBG concentration. The result is expressed as a ratio, which helps determine the relative amount of free testosterone in the bloodstream.

If the blood test for testosterone results yield a positive diagnosis, treatment options will depend on the underlying condition causing the hormonal imbalance. Treatments may involve:

  • Medications: Hormone replacement therapy or medications to regulate androgen levels.
  • Lifestyle changes: Adopting a healthy diet, regular exercise, and stress management techniques.
  • Surgical interventions: In some cases, surgical procedures may be necessary to address specific conditions.

The benefits of getting tested and diagnosed for hormonal imbalances early are as follows:

1. Accurate Assessment: The Free Androgen Index (FAI) test provides a precise evaluation of androgen levels, allowing for accurate diagnoses and targeted treatments.

2. Timely Intervention: Early detection of hormonal imbalances can prevent the progression of related conditions and minimise potential complications.

3. Personalized Care: Prompt diagnosis enables healthcare professionals to develop individualised treatment plans tailored to each patient's needs.
