Testosterone Test - Total

This Total Testosterone test provides a measurement of all forms of testosterone in the blood in one single reading. This provides an overall measurement of the total testosterone levels but does not break down the individual levels of each form of testosterone.

In contrast, our Free and Total Testosterone Test measures both the total testosterone (which includes all three forms) and the free testosterone (which circulates unbound in the blood). This test offers a more detailed view by providing the amount of testosterone that is not bound and is freely available for use by the body, in addition to the total testosterone levels.

Free testosterone is crucial because it is the biologically active form that can readily enter cells and exert its effects. Although it constitutes a small percentage of the total testosterone, its measurement can be particularly important in certain situations, such as evaluating hypogonadism or monitoring testosterone replacement therapy.

In essence, this "Total" testosterone test gives a broad overview of testosterone levels, encompassing all its forms, while the "Free and Total" testosterone test offers a more nuanced picture by separating the free testosterone from the total. This distinction is important for diagnosing and managing conditions related to testosterone levels more effectively.

Testosterone testing is used to evaluate androgen excess or deficiency related to gonadal function, adrenal function, or tumor activity. Testosterone levels may be helpful in men for the diagnosis of hypogonadism, hypopituitarism, Klinefelter syndrome, and impotence (low values).

Testosterone levels may be requested in women to investigate the cause of hirsutism, anovulation, amenorrhea, virilization, masculinizing tumors of the ovary, tumors of the adrenal cortices, and congenital adrenal hyperplasia (high values).

Reduced levels of testosterone in men can lead to:

• Infertility
• Decrease in libido/sex drive
• Erectile dysfunction
• Decreased muscle tone
• Moodiness
• Increase in body fat/enlarged breasts

Women should consider testing if:

• They are concerned about infertility
• Have thinning scalp hair
• Have heavy vaginal bleeding
• Experience low libido
• Have menopausal women
• Irregular or missed periods
• Have unusual bouts of acne or facial/body hair growth
