The low-cost and confidential online blood test make it a convenient alternative for patients without insurance or without a doctor’s order.Sex Hormone Binding Globulin (SHBG), is a protein produced by the liver. It binds tightly to the hormones, dihydrotestosterone (DHT), testosterone and estradiol (an estrogen), transporting them in the blood in a metabolically inactive form. The amount of SHBG in a patient’s blood is affected by sex and age, increased or decreased testosterone or estrogen production. It can also be affected by diseases and conditions such as obesity, liver disease, andhyperthyroidismorhypothyroidism. Adult males test SHBG and testosterone levels to help determine the cause of infertility, decreased sex drive and erectile dysfunction, especially when total testosterone results are found inconsistent with clinical signs.
