What It Measures

This test measures the level of androstenedione in your blood. Results may help evaluate adrenal and gonadal function and could indicate how efficiently your body converts this precursor into testosterone and estrogen.

Why It Matters

For men, androstenedione is a direct building block for testosterone. Abnormal levels may indicate issues with testosterone synthesis or adrenal function. Your healthcare provider can assess whether further investigation is needed.

When to Test

Testing may be recommended when investigating symptoms of hormonal imbalance such as irregular periods, excess hair growth, or acne. Your healthcare provider might suggest morning testing, as levels can vary throughout the day.

Symptoms

Low Levels

Some people may experience fatigue, decreased libido, or reduced muscle mass when androstenedione levels are below the expected range. These symptoms could suggest insufficient sex hormone precursor production. A healthcare provider can help evaluate the cause.

High Levels

Some people may experience acne, oily skin, excess body hair, or menstrual irregularities when androstenedione levels are elevated. High levels could suggest adrenal hyperactivity or conditions like PCOS. Discuss results with your healthcare provider.

Lifestyle Tips

Regular physical activity, maintaining a healthy weight, and managing stress through relaxation techniques may support balanced hormone levels. A diet rich in whole foods and adequate sleep could also contribute to hormonal health. Consult your healthcare provider.
