Note:

The Free Androgen Index (FAI) is a calculated ratio that estimates the bioavailable testosterone in circulation. It is commonly used in the assessment of androgen status in both males and females.

Reference Ranges:

• Males: 30 - 150
• Females: 5 - 40

Values outside the normal range may indicate hormonal imbalances and should be interpreted in conjunction with clinical findings.
