Is Hormone Testing Useful?

“I am experiencing many signs of perimenopause. I can’t sleep, I’m tired all the time, I’m anxious about everything and OMG, the flooding periods. I went to my doctor and asked to have my hormones tested. He refused, and told me that it wouldn’t be useful because I was too young (42) and hormone levels change constantly. He did do an FSH and it was in “normal” range. I was offered birth control pills and an antidepressant, but I don’t want that! I know there’s something hormonal going on and I want to get to the bottom of it. Help!”

Hormone balance is essential to good health for women of all ages. Unfortunately, for women in early midlife, the scenario above is all too common. Hormone testing is dismissed out of hand as being useless. In my opinion, this reaction tends to come from providers who have no idea what to do with the information they might get from testing and are uncomfortable prescribing hormones at all. This leaves many women suffering when they shouldn’t have to!

It is true that hormone testing is a snapshot in time (as are all lab tests) and that levels fluctuate, but in my practice, I find testing useful to look at the magnitude of the imbalances that may be present and the metabolic pathways the woman’s body prefers. Yes, your estrogen may fluctuate, but if it’s way out of balance with progesterone, that imbalance is unlikely to correct itself at certain times during the day or month if the testing is done at the correct time in a cycle.

Let’s look at the kinds of testing and what’s best for specific hormone replacement products. Matching the type of testing with the type of hormone supplementation (if prescribed) has a great impact on the clinical usefulness of hormone assessments. If you’re measuring with the wrong method, tissue uptake of the supplemented hormone may not be accurately reflected in test results, leading to inappropriate dosing.

Baseline (no hormone replacement)

Any testing method can be used to assess baseline levels of hormones. My favorite test is the DUTCH (dried urine) for its ease of use and the fact that it gives hormone metabolites.  This allows me to see the how your body is USING the hormone and whether or not you are clearing them appropriately. I use this information when creating a customized plan to provide support to pathways that may not be healthy.

Saliva for baseline testing has a few drawbacks. It is highly dependent on lab quality and does not provide cortisol metabolites which are necessary to accurately assess adrenal function.

Topical progesterone (creams)

Creams and gels cannot be effectively monitored with any lab testing. With the DUTCH test or serum testing, values increase only slightly (if at all) with dosing. With saliva testing, lab values are very high, leading prescribers to reduce doses inappropriately. Levels can stay elevated for months after therapy is discontinued.

Oral progesterone

The DUTCH test provides useful feedback when using oral progesterone to help with sleep. One of the metabolites is associated with better outcomes relative to sleep and this is the only test that provides that information. With serum and saliva, results go up and down quickly. If taken at bedtime, levels return to baseline within a few hours. Results can also be inaccurate due to progesterone metabolites cross-reacting with immunoassay tests.

Sublingual hormones (troches, lozenges)

No testing methods are accurate for monitoring dosing, however, the DUTCH test will still provide metabolite patterns.

Topical estrogen (gels, creams, sprays)

For the DUTCH test, target values between the top of the postmenopausal range and the lower third of the premenopausal range correlate with patient clinical improvement (bone density, hot flash relief, etc.). Doses that push levels to the middle of the premenopausal range and beyond may be excessive. DUTCH is preferred over serum due to the inclusion of metabolites. If using saliva, values are variable and may not correlate with symptoms.

Oral estrogen

Serum and saliva can be used to monitor oral estrogen therapy. However, the DUTCH test is not useful because much of the dose is stripped out in the liver, leading to lower urine excretion. The DUTCH test can still be used to assess metabolite patterns.

Patches, pellets and injections

Any method (serum, blood spot, saliva, DUTCH) can be used for follow up. Saliva may be less accurate than serum. Only DUTCH gives metabolic patterns in addition to hormone levels.

A word about follicle-stimulating hormone (FSH) testing

FSH is a blood test that’s commonly used to assess the hormonal status of perimenopausal women who may complain of hot flashes, mood changes, or other symptoms. But here’s the problem. It only gives an indication of how hard your body is working to produce an egg. The higher the number, the closer you are to menopause. It says NOTHING about sex hormone production or the relative imbalances. And it can fluctuate widely during the decade before menopause.

Even though there are no perfect testing methods, my preference is a “test-don’t-guess” approach. Having data allows me to create a plan that is customized to a client’s specific needs and to work with her doctor if needed to get bioidentical hormones on board. The “test-don’t-guess” approach is far superior to “guess and treat”.

Unfortunately, the guess-and-treat approach is still far too common in clinical practice. Most physicians would never prescribe drugs such as a blood pressure drug or cholesterol-lowering medication without monitoring the patient appropriately. Many are, however, very willing to prescribe potent hormones without clearly understanding how the woman’s body is using them. This can result in preventable adverse effects and poor clinical outcomes; not to mention unhappy patients.

    Hi, I live in Scotland in the UK where we have a shortage of menopause experts. Would you consider advising me on hormone therapy from a distance? Would I order a Dutch test here and email you the results? Let me know if you think this would be viable. Many thanks , Emma

  2. Hi Dr. Anna,
    I am 39. I have many of the symptoms you talk about. Fatigue, weight gain (I exercise regularly and eat well), sleep problems, irregular periods, mood swings, and period symptoms 3-4 weeks out of the month (boobs and armpit pressure/hurting as the most common). When I went to a midwife last year she was sure I was low on progesterone. She did blood testing for my hormones and all WNL. She had me start Vit D because my level was low but offered no other treatment. My Vit D tests are now normal, but I am still having all the same symptoms. My thyroid tests have always been normal. I have been on low dose antidepressant for many years that helps with the mood swings I have always seemed to deal with. Can you offer any advice on what I should do next.
    Thanks
    Stacy

    • Hi Stacy…your hormones could be “normal” on ranges but still be very out of balance with each other…and that’s what’s important. The ranges for hormones are huge and it would be very easy to fall into normal. I am not a fan of blood testing…I’ve been using the DUTCH test for the past year and it provides SOOOO much information that blood testing could never do. That would be my suggested next step. I offer this if you’d like more info.
