Free Testosterone, Equilibrium Ultrafiltration With Total Testosterone Test

This test measures both Free Testosterone using the Equilibrium Ultrafiltration methodology and Total Testosterone. 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.

The majority of testosterone is bound to the proteins Sex Hormone-Binding Globulin and Albumin. The portion of testosterone which is not bound is known as Free Testosterone. Free Testosterone is available for the body to use. This test uses a different testing methodology than a standard Direct Free Testosterone Blood Test. The equilibrium ultrafiltration test measures the percentage of free testosterone in a sample and uses that to calculate the free testosterone level. Unlike a Direct Free Testosterone Test, this test has established reference intervals for people age 0-19.

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. Measuring both total and free testosterone at the same time can give a more complete picture of testosterone levels, especially when someone has irregular levels of proteins such as Sex Hormone Binding Globulin.

Turnaround for this 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.
