Purpose of the test
The primary objective of the Free Androgen Index (FAI) test is to measure and assess the levels of androgens, specifically testosterone, in the blood. This test provides a ratio that compares the total testosterone to a protein called sex-hormone binding globulin (SHBG). By doing so, it helps in determining whether an individual has abnormal androgen levels, which can be indicative of various health conditions or hormonal imbalances.
Who Should Get Tested
Both men and women can benefit from the FAI test. Individuals showing signs of abnormal androgen levels are prime candidates. For women, symptoms like excessive body or facial hair, fatigue, bone mass loss, or decreased sexual interest might indicate the need for testing. In men, the test is relevant if there are signs of delayed puberty in teens or symptoms like muscle strength loss, breast development, or diminished sexual interest in adults.
Blood Test Preparation Guidelines
Time of day
It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.
Fasting
It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.
Stay hydrated
Drinking water prior to testing can help with sample collection.
Other factors
Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.
Medications and supplements:
Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.
Biotin supplements:
High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.
Interpreting Test Results
Test results can vary based on age, gender, health history, and other factors. It's essential to understand that results falling outside the "normal" range might not necessarily indicate a problem. For instance, males typically have testosterone levels ranging from 270 to 1,070 ng/dL, while females have levels between 15 to 70 ng/dL. Any significant deviations from these ranges might warrant further investigation. It's always best to consult with a healthcare provider to interpret the results in the context of individual health and symptoms.
