This test measures testosterone levels using the Liquid Chromatography and Tandem Mass Spectrometry (LC/MS-MS) methodology. Testosterone is the primary male sex hormone. However, it is present in both men and women. In men, testosterone is produced primarily in the testicles. Small amounts of testosterone are produced by the ovaries in women and the adrenal glands in both sexes. Measuring testosterone can help to diagnose the cause for a number of conditions in men such as delayed or early puberty, erectile dysfunction, and testicular tumors. It can also help evaluate conditions which affect both men and women such as decreased sex drive, infertility and pituitary disorders.
This test is intended to measure testosterone in people for whom a standard Testosterone Blood Test may not be sensitive enough to provide accurate results. For certain groups of people who typically have lower testosterone levels such as women, children and men whose bodies do not produce enough testosterone (hypogonadism), a LC/MS-MS test may be a better option.
This test is typically ordered to monitor testosterone levels in men who have been diagnosed with hypogonadism or are showing symptoms such as infertility, erectile dysfunction, decrease in muscle mass, lack of facial or body hair growth, osteoporosis, decreased sex drive or fatigue. This test is also ordered for women who are showing symptoms of abnormal testosterone levels such as abnormal facial or body hair growth, thinning hair, acne, abnormal menstrual periods, infertility, low sex drive, osteoporosis, fatigue and depression. It may be used to test children who are showing signs of delayed or premature puberty.
Turnaround time for the Testosterone test is typically 3-5 business days.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
