Free Testosterone, Direct (Analog Immunoassay) details
What Free Testosterone, Direct (Analog Immunoassay) shows
This directly measures the small, unbound portion of testosterone that's biologically active in your tissues, using a method that measures free testosterone more directly rather than calculating it from total testosterone and SHBG. It's used similarly to a calculated free testosterone result — often considered a more accurate reflection of your true androgen status than total testosterone alone, particularly when SHBG levels are abnormal and might otherwise distort the total testosterone picture.
Tests that include Free Testosterone, Direct (Analog Immunoassay)
Free testosterone is the biologically active form of testosterone not bound to proteins in the blood. Measuring free testosterone helps evaluate hormonal imbalances and can aid in diagnosing conditions related to reproductive or endocrine function in both men and women.
- Free Testosterone, Direct (Analog Immunoassay) Directly measures the small, unbound portion of testosterone that's biologically active in your tissues.
Testosterone, Free, Direct with Total Testosterone provides a comprehensive evaluation of androgen status.

This panel is useful for assessing hormonal imbalances and related symptoms.
- Testosterone The primary male sex hormone, also present in women in smaller amounts. Evaluated for low testosterone symptoms, fertility, and reproductive hormone imbalances.
- Free Testosterone, Direct (Analog Immunoassay) Directly measures the small, unbound portion of testosterone that's biologically active in your tissues.
Testosterone, Free, Direct With Total Testosterone, LC/MS-MS provides a comprehensive evaluation of androgen status. Total testosterone reflects the overall amount of testosterone in the bloodstream, while direct free testosterone represents the unbound, biologically active portion available for use by the body. This panel is valuable for evaluating androgen status in patients with symptoms of hormonal imbalance, such as infertility, sexual dysfunction, or irregular menstrual cycles. It helps differentiate between primary and secondary hypogonadism and is also useful for monitoring testosterone replacement therapy.
