Free Testosterone, Direct (Female)

Metabolic Health

A healthy result should fall into the range 0 - 4.2 pg/mL.

Although Testosterone is generally viewed as a male-only hormone, women’s ovaries also make small amounts of testosterone. It helps many organs and body processes in women.

The pituitary gland in the brain controls the amount of testosterone the body makes.

Most of the testosterone in the blood attaches to 2 proteins: albumin and sex hormone binding globulin (SHBG).

Some testosterone is called free if it is not attached to proteins.

Free testosterone and albumin-bound testosterone are also referred to as bioavailable testosterone. This is the testosterone that is easily used by your body.
