Testosterone Blood Test


Test Code: 004226
Specimen Type: Blood

Description:

Testosterone Blood Test

This test measures Testosterone levels in the blood.  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.  Testosterone stimulates the development of secondary sex characteristics during puberty in men.  In adult men, testosterone regulates sex drive and helps maintain muscle mass.  Luteinizing Hormone (LH), which is produced by the Pituitary Gland, controls how much testosterone is produced.  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.

Testosterone testing is commonly ordered for men who are experiencing erectile dysfunction, loss of muscle mass, fertility issues or decreased sex drive.  It may also be ordered for boys who are showing signs of delayed or early puberty.

A testosterone test may be ordered for women who are having irregular menstrual periods, difficulty becoming pregnant or are experiencing symptoms such as hair loss, low voice and excessive facial or body hair.

A testosterone blood test may be ordered with a Sex Hormone-Binding Globulin, Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH) or other hormone tests.

While a total testosterone test is most common, certain conditions may make a test for Free Testosterone more useful.

Turnaround time for the Testosterone test is typically 1-3 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.

Requirements:

It is recommended that someone taking Biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) stop consumption at least 72 hours prior to the collection of a sample.

Dietary supplements containing biotin (also known as vitamin B7 or B8, vitamin H, or coenzyme R) may interfere in assays and may skew results to be either falsely high or falsely low. For people receiving the recommended daily doses of biotin, draw samples at least 8 hours following the last biotin supplementation. For people on mega-doses of biotin supplements, draw samples at least 72 hours following the last biotin supplementation.
