# Testosterone, Free, Direct

> This test measures the amount of testosterone in your blood that is not attached to proteins, which is the active form of the hormone available for your body to use. It helps show whether symptoms like excess hair growth in women or sexual dysfunction in men are caused by available hormone levels, even if total testosterone appears normal. This is particularly helpful for evaluating hormonal health when conditions like obesity or thyroid disorders affect how proteins carry hormones in the blood. While this test identifies abnormal levels of active testosterone, it cannot determine the specific underlying cause of the imbalance without additional medical evaluation.
