What's Tested and Why
This test analyzes 3 important health markers to give you comprehensive insights into your wellbeing.
SHBG
Sex Hormone Binding Globulin
Why it matters: A protein that binds to testosterone. High levels mean less free testosterone is available for your body to use.
Testosterone
Total testosterone - an androgen hormone present in both men and women
Why it matters: While often thought of as a male hormone, women also produce testosterone. Elevated levels in women can indicate PCOS, ovarian/adrenal conditions, or other hormonal imbalances causing symptoms like irregular periods, excess hair growth, acne, and weight gain.
Free Androgen Index (FAI)
Calculated Androgen Activity Marker
Why it matters: The Free Androgen Index estimates how much active testosterone is available in the body. By assessing Testosterone alongside SHBG, the FAI provides a more meaningful picture of androgen activity and may help identify hormone imbalances linked to symptoms such as irregular periods, acne, excess hair growth, fatigue, low libido, and fertility concerns.
