This blood test is for men and women who want to check their balance of male and female hormones.
This test includes (expand individual tests for details):
Testosterone is a male sex hormone produced in the testicles of men. It is produced in much smaller amounts, in the ovaries of women. It is responsible for bone and muscle strength, as well as mood, energy and sexual function.
Oestradiol (E2) is produced in women mainly in the ovary. It is responsible for the female reproductive system as well as the growth of breast tissue and bone thickness. Normal levels of oestradiol provide for proper ovulation, conception, and pregnancy, in addition to promoting healthy bone structure and regulating cholesterol levels in females. In men, the testes, adrenal glands and fat tissue are the principal source of oestrogens. Oestradiol can be raised in men due to excess fat (which produces oestradiol) or in relation to testosterone levels which have declined with age. Raised oestradiol in men can cause the growth of breast tissue, the loss of libido and infertility.
Sex Hormone Binding Globulin
Sex hormones, like testosterone and oestrogen are bound to sex hormone binding globulin (SHBG.) When they are bound they are unavailable to your cells. High SHBG levels means there is less unbound hormones available to the cells. Low SHBG levels means you may have an excess of available hormones.
