hormone testing FOR WOMEN

IN order to demystify hormone testing, there are three truths you need to know:

  • Women's hormone testing generally focuses on ONLY sex, adrenal, and thyroid hormones.
  • There is NO ONE comprehensive test that will get you everything that you need.
  • "Normal" ranges for test results may not be YOUR normal.  













Though there are a laundry list of hormones that function daily in our bodies, the tests that we generally order focus on the trifecta of sex, adrenal, and thyroid hormones.  We look at the normal ranges of feminine hormones - estrogen, progesterone, and testosterone - but also the subsets of estrogen within those, as well as important thyroid and adrenal hormones.  All of these systems are connected and rely on each other to keep your total hormonal levels balanced at any given time in the body.


Some tests are better than others for checking certain levels, and some hormones fluctuate on a daily level, so they need to be tested more than once at specific times within a day.  In actuality, you may need more than one test to get a comprehensive look at your current hormonal levels.

And although the medical community has developed what is accepted as a “normal” range, that doesn’t take into account your unique history and genetic makeup.  What is “normal” on paper may not be normal for you.  If you fall close to either the bottom or top range of a level, there may be an underlying issue.  In addition, some hormones are dependent on others, so, for example, a low normal in one area with an abnormal level in another may indicate the precursor of a developing issue.  Be sure to discuss your results as a whole with a respected healthcare provider who will take into consideration your entire health history in addition to these test results.

CBC - Complete Blood Count

 Most blood tests begin with what is called a CBC, or a Complete Blood Count, to breakdown and evaluate the blood cells in your body to get an accurate picture of your bodily levels.  It looks at the following:

 

RBCs (Red Blood Cells) 4 million to 5 million cells/mcL

carry oxygen and filter carbon dioxide; a stable number helps keep your body fueled; too low signifies anemia

 

WBCs (White Blood Cells) 4,500 to 10,000 cells/mcL

help your body to fight infection; high levels indicate inflammation or infection; low means your immune system is compromised

 

Platelets 140,000 to 450,000 cells/mcL

help your blood to clot

 

Hb or Hbg (Hemoglobin) 12-15 gm/dL

protein that holds oxygen

 

Hct (Hematocrit) between 36%-44%

percentage of red blood cells to total blood; low scores mean you need iron, while high scores indicate dehydration or other issues

 

MCV (Mean Corpuscular Volume) between 80-95

average size of your RBCs; larger than normal cells indicate vitamin or folate deficiencies; smaller indicate a form of anemia

Your trusted healthcare provider should look for any discrepancies in these levels and also take into consideration the results of these levels in relation to your hormonal levels and any other tests that you request.

 

HORMONES TESTED


While there are many hormones at work in the body, hormone testing generally focuses on three areas:  sex hormones, adrenal hormones, and thyroid hormones. Why those three? Because they control the majority of the hormonal work of the body.  When we have an accurate picture of what is happening in those three areas, we can begin to understand what is happening in your body when considering symptoms, issues, and other concerns.


Let’s take a look at these three areas and the hormones for each…

 

Sex Hormones

Because your hormonal levels fluctuate through each phase of your menstrual cycle, these levels are listed as ranges within each of these phases.  Your test results should indicate which phase you are in if you aren’t sure yourself. For more information on the phases of your menstrual cycle and how to support your hormones through each, check out my article here.


Estrone (E1) - greatly influences tissue growth; protects the heart, blood vessels, and brain; may contribute to estrogen-dominant issues and often considered pro-carcinogenic; metabolites are either good or bad depending on individual nutritional standing; levels fluctuate depending on menstrual stage

Adrenal Hormones

Cortisol - levels of this hormone indicate how well your body handles stress; fluctuates throughout the day; should be measured in the morning via blood, and then 4x throughout the day via saliva

Serum Cortisol in AM  - shows levels of this glucocorticoid hormone released from adrenal cortex to show how you handle stress 10-20 mcg/dL 

Four Diurnal Cortisol (Tested 4x day via saliva) 3.1 - 22.4 ????g/dL 

 

DHEA-S (Dehydroepiandrosterone sulfate) - most abundant sex hormone in body; main precursor to estrogen and testosterone; levels affected by menstruation; affects immune system, cognition, bone health, and prevents aging

35 - 430 ????g/dL 


Prolactin - keeps other hormones in balance by inhibiting production; regulates metabolization of calcium; helps regulate inflammation and metabolic processes; stimulates breast milk production in lactating women

1.9 - 23.1 ng/mL

When you assess the test results, pay attention to the “normal ranges.” Discuss them with your trusted health-care provider, and bear in mind that just because your number falls into the “normal” range, that doesn’t mean that it’s normal for you. Any number at the higher or lower end should be questioned.

 

HORMONE TEST TRIFECTA 

There are actually three different tests that I recommend to my patients to get the most comprehensive results for their hormone levels so we can really figure out what is going on:  Blood, Saliva, and Urine. Each has its own merits, but there are also drawbacks to each. In a nutshell, the best solution is to get a combination of tests, or choose the one that best fits your specific needs.

 

Blood Test - CBC


In addition to the CBC for an overall look at blood levels, I recommend blood testing for thyroid levels.  It gives us a snapshot only of a moment in time, but allows us to test a wide range of thyroid hormones for a specific look at active levels.  If we notice discrepancies, then we can go back and order more blood testing to see where and when levels are varying.


The drawback to blood testing for thyroid levels is that it is hard to tell the difference between bound and free hormone levels.  Free levels are very relevant when we look at how much of a hormone is available for use in your body, a level that many doctors overlook.

 

Saliva Test

Saliva tests are great for cortisol levels because they are comprehensive and most can be done in the comfort of your own home.  This is ideal, since this test is best when repeated at multiple points throughout the day; at the bare minimum it should be done in the morning and then the evening, since your cortisol levels should fluctuate during your day.  

The drawbacks to saliva testing lie in the fact that the convenience of DIY opens it up to human error.  You have to follow the instructions explicitly, avoiding eating, teeth brushing, mouth washing, gum chewing, etc. in order to have accurate results.  They can also be altered if you are using prescribed topical hormones, so don’t choose this test if you fall in that category. Plus, these tests are only available for steroid hormones, not thyroid hormones, so it won’t give you a complete picture.

 

Urine Test - DUTCH (Dried Urine Test for Comprehensive Hormones)

An amazing gain in testing is the more recent DUTCH tests, which uses samples of urine throughout the day to test for a comprehensive panel of hormonal levels.  You simply soak a pad with pee and then let it dry before sending it in. It collects a huge amount of data, including sex and adrenal hormones plus metabolites, which gives a wider perspective for hormonal levels.

The drawbacks are that it is expensive and the results are complicated.  Even if you can do individual collection of multiple samples, the results still need to be interpreted by a medical professional.  But the sheer quantity of the results often make it worth it, especially for your metabolite levels.

 

THE BOTTOM LINE

Only you and your trusted healthcare provider can decide what are the best tests for you, though I recommend asking for the following:

  • CBC
  • Thyroid tests, including TSH, Free T3, Free T4, Reverse T3, TPOAb, and AntiTgAb
  • Adrenal tests, including Morning Serum Cortisol, 4 diurnal Saliva Cortisol tests, Free & Total Testosterone, and DHEA
  • Progesterone on day 21-23 (if cycling)
  • Fasting Insulin and Glucose, HDL, and Hemoglobin A1C
  • IGF-1 (growth hormone)
  • 25-hydroxy-vitaminD, Vitamin B12, and Folate


Together you can assess your results, taking into consideration your current age, lifestyle, and symptoms that you may be experiencing.  Remember that YOU are in charge of your own healthcare. Trust yourself and your inclinations when having these important conversations with your healthcare providers.
