What is a Testosterone Test?†
A testosterone test is a blood test that confirms the level of testosterone in the blood. Testosterone affects sexual features and development.
The Testosterone Test is part of our Menís Essential and Menís Essential Plus Screening Panels.
TestingWhy should I get tested?
Men might want to consider a Testosterone Test if they are having problems fathering a child (infertility), experiencing decreased sex drive,† or are having trouble getting or maintaining an erection (Erectile Dysfunction, also known as ED).†† Also, a Testosterone Test may help determine the cause of osteoporosis in men.
Women might want to consider a Testosterone Test if they are having irregular menstrual periods, decreased sex drive, or to find out why they are developing male characteristics, such as excessive hair on the face or body (hirsutism) or a deep voice.
How should I prepare for the test?
A Testosterone Test does not require any special preparation.
ResultsWhat could my screening results mean?
High levels of testosterone may indicate cancer of the testicles or adrenal glands in men, and in young boys it may be an indication of early puberty, a tumor in the testicles, or an abnormal adrenal gland.
If women have a high level of testosterone, it may be an indication of cancer of the ovaries or adrenal glands or polycystic ovary syndrome (PCOS).
Low levels of testosterone in men or boys who have gone through puberty may indicate slow development of the testicles, an injury to the testicles, liver disease (cirrhosis), and chronic alcohol use.
In women, a low testosterone level may indicate an underactive pituitary gland, Addison's disease, loss of ovary function through illness or surgery, and some medicines including corticosteroids or estrogen.
There are many conditions that could cause high or low levels of testosterone.† If your Testosterone Test indicates abnormalities, you should consult your healthcare provider for further analysis.
