| DIAGNOSTIC TESTS TO DETERMINE IF YOU
ARE GOING THROUGH EARLY MENOPAUSE Okay,
so you think you might be experiencing early menopause or premature ovarian failure.
You've noticed a number of symptoms, and you suspect menopause might be at the heart of
the matter. Now what? How can you be sure what is happening to you is
menopause or POF and not something else? The only way to be sure, as you would
expect, is to see your doctor.
Even then, you may run into problems. If your doctor
has the knee-jerk reaction that a woman in her 20s or 30s is too young for menopause, you
may wind up being misdiagnosed as suffering from anything from stress (the old catch-all)
to absolutely nothing -- the "it's all in your head" diagnosis. This is why it
is important for you to know what tests to ask for -- and to know what those tests mean.
Following, then, is a list of the different hormone tests
that may help you determine just what's happening with your body -- and whether or not
your ovarian function is showing signs of menopause or ovarian failure.
Some important points to keep in mind:
-- In general, if you're still getting a period, most
doctors recommend that you get your blood levels taken on day 3 of your cycle --
that is, the third day of your period. If you no longer are getting a period,
then you can get tested at any time.
-- Because hormone levels can and do fluctuate, many
doctors advise getting tested more than once -- about a month apart. This is
particularly important if you are still getting your period and/or have few symptoms, as
there is a slim chance you're experiencing what is sometimes called "temporary
menopause" -- a condition sometimes brought on by traumatic stress among other
things. It's also important if your hormone levels come back normal, but you are
experiencing definite symptoms, since you may indeed be beginning menopause, but your
hormone levels didn't show it at that particular time.
-- Different labs may use different ranges in their
testing. So if and when you do get tested, be sure to ask your doctor not only for
your specific results, but also for the range used by the lab.
Here, then, are the specific tests you may want to consider
asking for:
FSH Blood Level Measurement
This is the key test to determine whether or not you are in menopause. A sample of
your blood is taken to measure the levels of FSH -- follicle stimulating hormone -- in
your blood. Because your FSH levels rise when your ovaries stop producing enough estrogen,
high FSH levels can signal that your body is entering menopause.
- Normal FSH day 3 value is 3-20 mlU/ml
- FSH levels above 10 to 12 mlu/ml indicate that your ovaries
are starting to fail. In other words, this means that you are in perimenopause --
the beginning stages of menopause when you notice physical symptoms, but before you have
stopped having a period for a year, or have "diminished ovarian reserve"
- Higher FSH levels -- levels about 30 to 40 or above -- are
usually taken to signal menopause or ovarian failure. You may even be getting
periods with your FSH levels this high, but it still is a sign that your body isn't
producing enough estrogen to maintain regular ovarian function.
- Keep in mind that you may end up with FSH levels that are
well in the post-menopausal range, but still be getting a period. This is one of the
things that differentiates premature menopause or premature ovarian failure from
"regular" menopause (i.e. menopause that occurs to older women after a full year
without a period). Yet again, this hammers home the unfortunate fact that you may
indeed be in premature menopause even if you're having periods. Once your FSH levels have
reached a certain height for a period of time, it's highly unlikely that they'll drop back
to premenopausal levels. In my case, even after my FSH was tested at over
150, I had apparently normal periods for eight months. Then when I was
retested -- hoping that somehow my body had snapped back to normal, I learned that my FSH
level had dropped. . . . but only to 126. Since my FSH levels had been well above 35
for over a year, I finally accepted that my ovaries had failed.
- As mentioned above, because hormone levels can and do
fluctuate, remember that the FSH is far from foolproof. Some women can test with a
high FSH, then revert to normal levels the next month...and so on. Again, it's
generally wise to get tested more than once.
FSH TEST LEVELS
| Normal Menstruating |
|
Follicular Phase |
2.5 to 10.2 |
Midcycle Peak |
3.4 to 33.4 |
Luteal Phase |
1.5 to 9.1 |
| Postmenopausal |
23.0 to >116.3 |
((Note: Lab
levels -- or "assay levels" -- do vary from lab to lab, so you may notice
different levels listed on your lab report)
Estrogen (Estradiol) Levels
Estradiol is the primary human estrogen -- and when your ovaries begin to
fail, your circulating estradiol levels drop. This is why doctors often give you a
serum estradiol concentration test to measure the amount of estradiol in your
blood. In this case, the doctor is looking to see if your estrogen levels are lower
than normal -- again, a signal of ovarian failure, or, in other words, early
menopause.
Normal estradiol Day 3 value -- 25-75 pg/ml
In spite of the above number, generally,
estradiol levels about 30 or below -- in conjunction with a high FSH
level (high in this case, meaning in the post-menopausal range, i.e. 30-40
or higher) -- is considered menopausal. (Important note: If your FSH
hasn't reached post-menopausal levels and your estradiol is on the low side, you are not
considered POF or EM. There can be other reasons for low estradiol, including
excessive exercise, low body fat, and diminished ovarian reserve.) This is because
estradiol levels tend to drop over time. During the first 2 to 5 years following
menopause or ovarian failure, blood levels of estradiol drop to an average range of about
25 to 35 pg/ml. Women not on HRT generally will see this number drop even more over
time; after about five years, it's common for menopausal women who aren't on HRT to have
estradiol levels below 25.
If your estradiol levels are lower than 50
picograms per milliliter, you may still be having a period, but also may be
experiencing symptoms of low estrogen -- including hot flashes, vaginal dryness, and
sleep difficulties.
| Non-menopausal: |
|
Follicular Phase |
24-138 |
Luteal Phase |
19-164 |
Periovulatory |
107-402 |
| Postmenopausal: |
|
No HRT |
<36 |
With HRT |
18-361 |
(Note:
Generally, it is recommended that you raise estradiol levels to a minimum of 40 to 50
pg/mL to prevent bone loss, but 60 pg/mL or higher is optimal -- with many specialists
advocating levels of about 100 pg/mL for younger women.)
Other Ovarian Hormones
It's not necessary to determine whether you are definitely menopausal or not, but --
depending on your symptoms -- you or your doctor may also want to test your levels of the
other major ovarian hormones: testosterone, progesterone, and luetinizing
hormone (LH).
Testosterone: There has been more attention
paid recently to testosterone -- and more doctors and studies have been concluding that
low levels are often a problem for a woman with premature ovarian failure or early
menopause (particularly women who've undergone surgical menopause).
The general rule of thumb is that total testosterone levels that are 25 ng/dL or
less is indicative of a deficiency, as are free testosterone levels of 1.5 pg/mL or
less. (Women over age 50 are considered to have a deficiency at a lower level -- 1.0
pg/mL or less.) But if you're just a little bit above these levels -- and have
symptoms of low testosterone such as a lagging libido or excessive fatigue -- then you may
still benefit from testosterone supplementation. (Some doctors and labs also
test bioavailable testosterone levels. Normal ranges for this are 0.6 - 5.0 ng/dl
for premenopausal women and 0.22-4.3 ng/dl for postmenopausal women who aren't on HRT.)
Progesterone: Most labs and studies
state that menopausal levels are about .03-.3 ng/ml. By way of comparison, premenopausal
women will have progesterone levels at about 7-38 ng/ml during their luteal phase.
Leutinizing Hormone (LH): normal day 3 LH
levels are 5-20 mlU/ml. If your LH levels are high in ratio to your FSH levels, this
could indicate that you aren't in menopause or going through premature ovarian failure,
but instead have polycystic ovarian syndrome (PCOS) which can cause some similar symptoms.
Finally, there's DHEA, another androgen.
This often isn't tested unless you have been exhibiting symptoms of low androgens
(as with testosterone, the symptoms include decrease in libido and energy levels).
For women under 50, DHEA levels of less than 150 ng/dL are considered low.
Thyroid
Many doctors will also recommend that you have your thyroid tested when you suspect
menopause. This makes sense for two reasons: First, many women in premature menopause also
are at a higher risk for thyroid problems. Second, many symptoms of thyroid disease
overlap with menopausal symptoms. In fact, thyroid diseases often interfere with
menstruation. Testing your thyroid, then, will help determine whether you are in premature
menopause -- or instead have thyroid disease. In this case, your doctor will probably
check your thyroxine and thyrotrophin levels.
Salivary Hormone Tests
Some doctors recommend saliva testing to measure hormone levels. This isn't as widely used
as blood testing, but advocates clam that it is quicker, less expensive and reliable.
There is, however, debate in the medical community about saliva testing -- with some
claiming that the blood levels are the better form of testing and others saying the same
about the saliva tests.
With salivary testing, your doctor takes
samples of your saliva to see the levels of hormones you are producing and to determine if
you have any deficiencies. Unlike the blood tests, the saliva hormone tests will
show the levels of "free" hormones in your body -- that is, the hormones that
aren't bound to proteins but instead are able to move into cells. Because
about 95% or more of your blood hormones are bound, the saliva tests measure only the
remaining 1 to 5% -- so the results may be markedly lower than that which you see on your
blood test results. In addition to getting saliva tests at your doctor's, you can
also order kits to test your hormone levels at home. If you do choose to do this, though,
be sure to go over any results with your doctor. There are several pharmacies on
line that offer saliva testing, including Aeron Labs
and Women's Health America.
Ultrasound
In some cases, your doctor may perform high resolution ovarian ultrasound to view your
ovaries. This will determine whether you still have any eggs and follicles. However,
generally, this information doesn't help that much. According to a British study, up to
two-thirds of women diagnosed with premature ovarian failure do indeed have remaining
follicles. The problem is, even when eggs are detected, attempts to stimulate ovulation
through hormones have been relatively unsuccessful. However, ultrasound may make
sense if you are in the early stages of premature menopause and are intending to pursue an
aggressive fertility program. |
