Estriol (E3) Home Health Test Kit - Saliva

Use the above tabs for extended information on this product.


Estriol is a steroid hormone and one of the three estrogens in a woman (estradiol and estrone are the others). This sexual hormone is secreted by the ovaries and its rate increases noticeably during pregnancy. Estriol is metabolized from estradiol, weaker than the other two, but still active. Although it is most commonly linked to pregnancy since it is produced in the most measurable amounts at that time, it is still present throughout a woman's lifetime at varying levels.

Your saliva samples will test: Estriol (E3) levels.

You may want to consider this test if you suffer from:

  • Bone loss
  • Decreased fertility
  • Depression
  • Hot flashes
  • Heavy or painful periods
  • Irregular periods
  • Irritability
  • Memory lapses
  • Mood swings
  • Nervousness
  • Night sweats
  • Poor concentration
  • Sleep disturbances
  • Tender or fibrocystic breasts
  • Vaginal dryness

Everything you need to collect your sample and return it to the lab is included in the test kit you will receive.

You can review these illustrated Collection Instructions now or wait to receive them in your package.

Your test results will be returned to us within 5 to 7 business days from the date the lab receives your sample. Once we know that your results are available, we will send you an email so that you can login and review them.

NOTE: Per state laws, if you live in California, you will need to email us a prescription from a medical practitioner (could be a physician, physician's assistant, naturopath etc.) in order for us to process your order and send you your test. New York residents may not receive tests per state laws. Having your tests shipped to you outside of California or New York may be the best way to go. (The Air Quality tests and Pet tests do NOT need a prescription and can be sent anywhere needed.)

Because the test kits include postage-paid return shipping, there is an extra shipping charge of $10.00 that will be added to your test order.


This Estriol Saliva Home Test will measure the estriol levels in your body and tell you if your estriol levels are within the expected optimal range depending on your age and sex. Even though estriol is considered to have the least significance of the three estrogens in the body due to its weak estrogenic activity, it shouldn't be ignored. This hormone has beneficial effects for bone density, cardiovascular health, multiple sclerosis and postmenopausal urinary tract health.

It's particularly useful during pregnancy to know if your estriol levels are within the expected optimal range. Research data has been leaning towards the concept that low levels of unbound estriol in pregnant women may indicate chromosomal or congenital anomalies like Down Syndrome or Edward's Syndrome.

Please note that because return postage is included with this test kit, there is an extra shipping charge of $10 for kits shipped in the USA. The extra shipping charges for kits shipped outside the USA will vary according to cost/location. (This extra charge is NOT added to the Canine Health Check Test Kit or Any of the Air Quality Test Kits.

Everything you need to collect your sample and return it to the lab is included. You should receive your results approximately 5 to 7 business days after the lab has received your sample. There are no additional lab or postage fees required after test purchase.

This is a safe, easy to use home hormone saliva test for men and women of any age.
