Cortisol: Cortisol is the body’s primary stress hormone. When the brain stimulates its release in response to physical or emotional stress, the adrenal glands secrete Cortisol into the general circulation. Cortisol helps the body regulate blood sugar levels, blood pressure, inflammation, the immune system, memory formulation. It also has a controlling effect on the body’s salt and water balance.

In women, Cortisol also supports the developing fetus during pregnancy.

Heat, cold, infection, trauma, stress, exercise, obesity, and debilitating disease can influence cortisol levels. The hormone is secreted in a daily pattern and it this pattern that is measured with the Comprehensive Cortisol Test.

Estradiol: (E2) Estradiol is the predominant form of estrogen. Estradiol imbalance can cause depression, increased body fat, decreased bone density and sexual dysfunction. In men, small amounts of estrogen are made as a by-product of testosterone conversion. It’s important that these levels remain low.

More: There is no ideal specimen type for measuring hormones since there are advantages to each, depending on clinical goals. In the case of stress hormones, the majority of circulating hormones are bound to proteins and are biologically inert. Salivary testing assesses unbound, biologically-active level of the hormone within your body.
