One Day Hormone Check (Genova Diagnostics)

The One Day Hormone Check is a salivary hormone test that evaluates unbound, bioavailable hormone levels over 24 hours. Specimens collected over 24 hours are examined for levels of estradiol, estrone, estriol, progesterone, the progesterone/estradiol ratio (P/E2), testosterone, cortisol, DHEA, and melatonin.

The One Day Hormone Check provides information about the impact that shifting hormone levels can have in men (andropause or male menopause) and women (perimenopause and menopause). It can reveal imbalances of primary sex hormones and how they relate to other hormones, such as DHEA, cortisol, and melatonin. Using hormone testing, clinicians can customize hormone and/or nutritional therapies and monitor therapy.

People with hormone imbalance may present with:

- Fatigue

- Weight loss or gain

- Menstrual irregularities

- Loss of libido

- Insomnia

- Changes in hair and skin

- Hot flashes

Note on reference ranges:

The therapeutic ranges depicted are for informational purposes only, and were derived from a cohort of peri/menopausal women ranging in age from 37-62 years. All women were treated with bioidentical hormone therapy (HT) utilizing combinations of the following: Biest (transdermal); Progesterone (oral micronized); Testosterone (transdermal); and 7-keto-DHEA (oral).

DHEA (7AM - 9AM)

Optimal range: 71 - 640 pg/mL

DHEA is a hormone produced by both the adrenal gland and the brain. DHEA leads to the production of androgens and estrogens. DHEA levels in the body begin to decrease after age 30. Levels decrease more quickly in women.

DHEA:Cortisol Ratio

Optimal range: 358 - 2538 Ratio

This calculation represents anabolic and catabolic balance. Since DHEA acts not only as an anabolic hormone, but appears to down-regulate the cellular effects of cortisol, this measurement can theoretically enhance the predictive value of HPA axis dysfunction.

An optimal ratio indicates proper HPA axis homeostasis.

Estradiol (E2)

Optimal range: 2.9 - 13.7 pmol/L

Estrogens play a critical role in female sexual development, menstrual function, protein synthesis, cardiovascular function, bone formation and remodeling, cognitive function, emotional balance and other important health factors. The estrogenic potency of estradiol is 12 times that of estrone and 80 times that of estriol. Estradiol is the primary estrogen in premenopausal women. Estrone is the second most potent estrogen compared to estradiol.

LEARN MORE

Estriol (E3)

Optimal range: 0 - 135 pmol/L

Estriol is considered to be the mildest and briefest-acting of the three estrogens.

Has weak estrogen activity. Considered to be a protective estrogen. Most prevalent estrogen in pregnancy.

LEARN MORE

Estrone (E1)

Optimal range: 36.6 - 253.2 pmol/L

Produced by the ovaries, the estrone hormone is one of three types of estrogen, and it is one of the major hormones found in the bodies of postmenopausal women. While research into estrone function is still ongoing, largely due to the fact that it is the least powerful of the three types of estrogen, women should still understand this hormone and its known effects on the body.

- Weaker compared to Estradiol (Research says the estrogenic activity is about 4% of estradiol’s activity)

- Most abundant in menopause

- Made via aromatization in several tissues like fat and muscle

- Converts into estradiol (E2)

Estrone (E1) is also made by the ovary but in fat tissue in lesser quantities. While not as abundant in circulation as estradiol, estrone excess can still increase the risk for estrogen dominant cancers as well as estrogen dominant symptoms such as breast tenderness, heavy menstrual cycles, headaches, and erectile dysfunction and breast development in men just like estradiol. Estrone is commonly thought to be more abundant during menopause. 

Estradiol and estrone can interconvert into each other.

P/E2 Ratio

Optimal range: 10 - 106 Ratio

The P/E2 ratio describes the relationship between progesterone and estradiol levels, and is used clinically to ascertain dominance of one hormone compared to the other.

LEARN MORE

Progesterone

Optimal range: 52 - 850 pmol/L

Progesterone is important for normal reproductive and menstrual function, and influences the health of bone, blood vessels, heart, brain, skin, and many other tissues and organs. As a precursor, progesterone is used by the body to make other steroid hormones, including DHEA, cortisol, estrogen and testosterone. In addition, progesterone plays an important role in mood, blood sugar balance, libido, and thyroid function, as well as adrenal gland health.

Salivary Cortisol (10PM-12AM)

Optimal range: 0 - 0.034 mcg/dL

Cortisol is a stress hormone produced by the adrenal glands and is the primary agent used in our body’s flight or fight response to threatening stimuli.

LEARN MORE

Salivary Cortisol (11AM-1PM)

Optimal range: 0.027 - 0.106 mcg/dL

Cortisol is a stress hormone produced by the adrenal glands and is the primary agent used in our body’s flight or fight response to threatening stimuli.

LEARN MORE

Salivary Cortisol (3PM-5PM)

Optimal range: 0.013 - 0.068 mcg/dL

Cortisol is a stress hormone produced by the adrenal glands and is the primary agent used in our body’s flight or fight response to threatening stimuli.

LEARN MORE

Salivary Cortisol (7AM-9AM)

Optimal range: 0.097 - 0.337 mcg/dL

Cortisol is a stress hormone produced by the adrenal glands and is the primary agent used in our body’s flight or fight response to threatening stimuli.

LEARN MORE

Salivary Melatonin (2:30AM - 3:30AM)

Optimal range: 3.71 - 33.38 pg/mL

Melatonin is not technically an adrenal or sex hormone however it is highly involved in the entire endocrine system. It is made in small amounts in the pineal gland in response to darkness and stimulated by Melanocyte Stimulating Hormone (MSH). 

LEARN MORE

Salivary Melatonin (3PM-5PM)

Optimal range: 0 - 1.97 pg/mL

Melatonin is not technically an adrenal or sex hormone however it is highly involved in the entire endocrine system. It is made in small amounts in the pineal gland in response to darkness and stimulated by Melanocyte Stimulating Hormone (MSH). 

LEARN MORE

Salivary Melatonin (7AM-9AM)

Optimal range: 0 - 12.12 pg/mL

Melatonin is not technically an adrenal or sex hormone however it is highly involved in the entire endocrine system. It is made in small amounts in the pineal gland in response to darkness and stimulated by Melanocyte Stimulating Hormone (MSH). 

LEARN MORE

Testosterone

Optimal range: 34 - 183 pmol/L

Testosterone is an androgenic sex steroid/hormone that helps maintain libido, influences muscle mass and weight loss, and plays a role in the production of several other hormones. During the aging process, testosterone levels gradually decline in both sexes, which can lead to loss of bone density. Testosterone concentrations tend to be higher in men versus women.
