Labrix™ saliva testing is an easy
non-invasive way of assessing your hormone balance. This information
allows you to supplement hormones according to a plan tailored for only
you. Well-balanced hormones regulate everything from reproduction to
emotions, general health and well-being. An imbalance of any one hormone
can throw your physical and mental health out of balance, causing
aggravating and even serious health problems.
Labrix uses one of the most advanced
processes available for accurately assessing hormone levels in saliva.
Labrix uses four saliva samples, timed throughout the day, for results
that accurately reflect your hormonal status, as some hormones levels vary
somewhat during the course of the day. Most other testing labs use just
one saliva sample collected in the morning.
Why is saliva used for
Saliva has several obvious advantages over
blood for testing of hormones. For example saliva:
- is simple to collect
- can be done in the privacy of your home
under stress-free conditions
- can be collected at the optimal time of
Blood, on the other hand:
- requires a specialist in blood
- must be done at the hospital or
- is stressful
- often cannot be collected at the proper
time of day
But the most important reason is that
saliva is the most accurate method of evaluating your hormone status. Only
about 1-5% of the hormones in blood are in the unbound or “free” form.
The remaining 95-99% are tightly bound to blood proteins. It is this
unbound fraction of hormones that enters tissues throughout your body,
including the salivary glands. Hence, salivary hormones are representative
of the free or unbound hormones in blood that are "bioavailable"
to tissues of your body.
Saliva testing is the most accurate method
of evaluating your hormone status, including how hormone replacement
therapy, topical hormone creams, diet, herbal therapy, and exercise
influence your hormone levels.
Who should be tested?
- Men and women concerned with decreasing
hormone levels as a result of age.
- Cycling women experiencing PMS symptoms,
perhaps related to a hormonal imbalance.
- Peri and postmenopausal women concerned
with their estradiol and progesterone levels for replacement
- Those wishing to monitor their hormone
levels following replacement therapy (oral, sublingual or topical),
and subsequently regulate their supplement levels.
- Anyone with symptoms involving fatigue,
insomnia, stress, immunity problems, blood sugar problems, and
overweight should be tested for cortisol levels as well as “sex”
Men and women of any age who are having
symptoms of hormone imbalances should test for all hormones that may be
associated with their symptoms.
Men and women over the age of forty may
want to do a baseline test. Frequently imbalances will be detectable for a
time period before symptoms gain attention.
How is the testing done?
Saliva collection is simple, non-invasive
and can be performed in the privacy of your home.
- First, you order the Labrix hormone test
kit of your choice from HerAnswer.com. Note: Please
make sure to include your correct e-mail address on your order since
your test results are returned to you via e-mail in a PDF file. This
is the only method for you to receive your results. We
do not send hard copies of test results via postal or ground services.
- The specimen collection kit is sent by
US Mail, to your home.
- The kit contains instructions for saliva
collection and four small plastic vials for collecting saliva
throughout the day.
- You choose a convenient day for testing
and follow the instructions. (You “spit” less than ½ teaspoon of
saliva into a plastic vial in the morning, before lunch, before supper
and at bedtime).
- Read the instructions thoroughly; not
following these instructions may contaminate your samples and cause
- Fill out the enclosed form and symptom
survey. This survey is essential to provide accurate feedback.
- Mail the test kit back to the lab.
(Hormones in saliva are stable for 7-10 days at room temperature, so
shipment by regular US mail will not compromise saliva test results.)
- When the lab receives the specimen it
will be tested using Enzyme Immuno Assay (EIA). This sensitive
methodology insures accurate results.
- Your hormone test
results will be sent by e-mail within 7 working days following receipt of the sample.
You will receive a report with your test
results via e-mail.

When should I do saliva
- Testing your baseline levels before
beginning hormone supplementation is essential to regaining hormone
- It is helpful to test on a day that
represents a “normal” daily schedule.
- Men may test on any day.
- For women still having menstrual
periods: test between day 19 and 21 of their menstrual cycle.
Count the 1st day of your period as day 1.
- If you are cycling
irregularly, make your best guess for testing 4 to 5 days after
ovulation. If you are so irregular that a guess is not practical, then
test any time that you not flowing. Irregular menstrual cycles are
usually indicative of hormone imbalances that will be picked up by the
- If you have regular, but short,
cycles (every 2 weeks or so), test 5 days before your period.
- For women NOT still having menstrual
periods: test on any day
Note: For men or women on oral or topical
hormone replacement therapy it is imperative to allow between 12 and 24
hours from the most recent dose to sample collection. Whereas, if you are
on troche or sublingual hormone replacement therapy allow a minimum of 36
hours between the most recent dosage and sample collection. If you wish to
test your baseline levels (your own hormone production) you will need to
be off of hormones for a minimum of 5 to 7 days.
Do I need to retest after
Baseline testing should be done before any
hormone replacement therapy is initiated. A retest within 2 months after
starting replacement therapy is recommended to evaluate its effectiveness.
This will verify that you have the optimal treatment approach. Once
hormone balance has been achieved testing once a year is sufficient.
I live in New York. Can you
test my saliva?
Is a saliva test beneficial
for women taking birth control pills?
is a suggestion for these women who do not intend to stop taking the pill
but show symptoms of low progesterone and testosterone? The saliva test
can be beneficial for anyone using hormones and/or contraceptives. It is
not uncommon for saliva testing to identify hormonal imbalances in women
using contraceptives. A suggestion for a woman using contraceptives with
symptoms of low progesterone and testosterone might be to test these two
hormones to identify whether an imbalance exists and to what extent. When
testing progesterone it is important to test estradiol at the same time to
establish a ratio. Saliva test results could then serve as a guideline to
help the patient and healthcare provider adjust the dosage of hormone in
the birth control pill accordingly.
