Saliva cortisol is far more accurate
than blood.

In 2002, when the Stop the Thyroid Madness movement began (even before it had that name), patients were discovering that there were a large body who had a cortisol problem as revealed by saliva cortisol testing, mostly low cortisol, but some high, and many mixed high and low.

Why is it problematic to have a cortisol problem?

Because without enough cortisol, thyroid hormones don’t do a good job getting to our cells, whether thyroid hormones made from our thyroid, or from thyroid meds. If on thyroid meds, especially NDT, or T4/T3, or T3-only, and we try to raise them in the presence of a cortisol problem, we start seeing our free T3 go far too high in the blood. This is called pooling. Even high cortisol is a problem.

What about high cortisol?

Even having too high cortisol can be a problem. Besides the insomnia it can cause in many of us at bedtime, or frequent wake-ups right after we did fall asleep, we also saw how high cortisol pushed our Reverse T3 (RT3) higher and higher, which will also make us more hypothyroid. RT3 is an inactive thyroid hormone.

Why did wise patients start using saliva cortisol testing instead of blood??

At first in the early groups Janie had started, patients were using blood because our doctors prescribed it (and sadly, still do).

But we quickly heard about saliva cortisol testing. Saliva not only tests our “available-for-use, cellular, unbound” cortisol, but at four key times. Blood does neither! Blood is measuring a combination of both bound and unbound cortisol, of which 80% or more can be bound and unusable! And blood testing, which is usually done once, doesn’t tell us what is going on the rest of the day.

Additionally, when in the early years patients were using both saliva and blood, some saw themselves with HIGH or good blood cortisol at a particular time, whereas the saliva showed LOW. And our symptoms FIT the low. That was insightful. So we quickly learned to say no to blood, and only use saliva cortisol testing.

What about urine testing??

The most common urine test that doctors try to prescribe is a 24 hour urine test. But all it does is give an “average” and tells us nothing about what is going in at four key times, which is crucial. Granted, it can be useful to diagnose Addison’s or Cushing’s disease. But most of us as thyroid patients with a cortisol issue have neither of those. We simply have a cortisol problem based on the stress we encountered from being undiagnosed for so long, or being put on Synthroid or Levo–the latter T4-only meds which, because they are inadequate, stress our adrenals.

Another bad urine test? The Dutch!! We’ve been shocked how many weird results have resulted from doing the Dutch cortisol test–results that don’t fit the person’s symptoms.

Here’s the process with using saliva cortisol testing:

  1. To prepare, drink lots of fluids the day before! Helps provide enough saliva the day of the spit.
  2. The day to do it is a normal, relaxing day.
  3. This is general, but you will spit into provided vials that will be sent to you. When??

a) first thing in the morning after awaking (and before eating),
b) around 11 am – 1 pm (before eating lunch),
c) around 4-5 pm (before eating supper–they will call this “evening” but it’s late afternoon), then
d) at bedtime, i.e.when your body is clearly telling you it’s time to go to bed (before brushing teeth). It’s important to stick to those times. Some will provide a vial for DHEA, but it’s not required.

4. What if you have weird hours than other people? Whatever time you normally wake up is your “first thing in the morning”, even if it’s late morning. Then approximately 4 hours later is “your noon”. Approximately 4-5 hours later is your “late afternoon” (which they call evening), etc.

5. How much in each vial? Most places recommend 3/4 full, but some are 1/2 full. It can take “up to” 30 minutes, but could be less.

6. If mouth is dry, some report sniffing things like a cut lemon or whatever might promote salivating. Do NOT chew gum or anything else to promote saliva. It will contaminate the sample.

7. For women, it may be important to wait until after a period and before mid-cycle. Why? Rising progesterone can affect cortisol to some degree in some people. If your periods are weird, or you are meno, don’t worry about when.

8. Avoiding exercise on the day of saliva may be important to prevent false cortisol levels.

9. We also try to be off supplementation or meds which can affect cortisol, and be off “up to” two weeks…if possible. Why? We are trying to see what our cortisol levels are naturally and without influence, and treat that. BUT…some people need what they are on, such as anti-depressants etc. Perhaps talk to your doctor to see if you can be off for a few days?

10. If sick, might want to wait until you are well. Sickness can affect cortisol levels.

11.Talk to your doctor if you have any additional questions. Your kit will also have instructions.

About the vials, plus how to send them back–important

Once you spit, we recommend immediately freezing them, one by one. Then you send the next day, or very soon. Why freezing?? Because we want them to arrive as fresh as possible, even if the company claims they are fine without doing this. We have noted weird results from not doing this for some people, as if hot weather degrades the saliva, or the time it takes to arrive degrades, or the facility doesn’t get to them quick enough. Granted, your results may fit your symptoms if you don’t freeze, but our observations over the years make us suspect. So our philosophy is why take the risk….

Additionally, we find it important to do overnight shipping with the frozen vials! Janie puts her frozen vials in a baggy, then wraps the baggy in paper towels and foil to further hold the cold in. Some facilities even provide a small bag you can freeze, then insert. But any method you use to keep them colder, longer, will work. It calms our concerns based on years of observations.

About facilities that use the “less than/more than” results rather than ranges

Avoid!! They don’t understand that it’s about “where” we fall that has meaning, not about “falling anywhere” below or above a number. My Med Lab uses ZRT which happily has all ranges. Sadly, Quest has a less-than range for bedtime. So does an Ulta saliva test. With Cell Science, too many people have gotten weird results that don’t match their symptoms.

Once I get my results back, how do I understand them?

NOT what they tell you. Use this: https://www.stopthethyroidmadness.com/lab-values You may have to teach this to your doctor.

How do I treat a cortisol problem revealed by my saliva test?

This is where you need the updated revision Stop the Thyroid Madness book, chapters 5 and 6. We all have to be informed in treating this. ——–> You can read more about this Bible of Thyroid Treatment here.

Why do I have a cortisol problem in the first place?

Please read the last chapter in the STTM II book as well–it does a bang-up job explaining how it all happens! Then there are Chapters 5 and 6 in the updated revision STTM book, shown above.
