Did you know that there were decades of successful treatment for hypothyroid that involved nothing more than dosing you by symptoms?  The TSH lab didn’t even come into existence until the mid-1970’s.

But lab work gives important clues and direction on top of those symptoms! 

**Many of these are also explained well in the revised STTM book. The book is in English, Spanish, German and Swedish.


IMPORTANT NOTE ABOUT THE SALIVA ADRENAL CORTISOL TEST MENTIONED BELOW:  Save your money and get the 4-point test, NOT the 6-point. It’s very adequate, say patients.

STTM graphic Labs which thyroid patients found invaluable

Summary: important labs patients report on include TSH to discern hypopituitary (i.e. low TSH with a low free T3), Free T3 and Free T4, Reverse T3, BOTH thyroid antibodies to detect Hashimoto’s, four iron labs (Ferritin, % Saturation, serum iron and TIBC), 24 hour Saliva cortisol (not blood), B12 and folate, magnesium, potassium (CMP), Vitamin D3 (and D2), MTHFR gene, Thyroglobulin if thyroid cancer is suspected. Others include whatever your doctor recommends.

ABOUT MAGNESIUM: the RBC magnesium is said to be most accurate since it can provide an earlier indicator of a deficiency than serum/blood magnesium.

OTHER LABWORK: Lyme testing is recommended if you just never seem to get well–IgeneX is preferred and more accurate. Epstein Barr Virus (EBV), Candida, etc. Direct Labs below has testing for Neurotransmitters, as well as hair testing. OAT (Organic Acids Test) is cutting edge about cellular blockages or nutrient deficiencies.


STTM Graphic Recommended Labwork A

STTM graphic Recommended Labwork B

Summary: TSH (with a low free T3) is more about hypopituitary; “Free” in front of T3 and T4 is measuring what is available for use unlike the the “total”; both anti-TPO and anti-thyroglobulin are needed, not just one; all four iron labs are needed because ferritin can be low due to high heavy metals, not just low iron; blood cortisol might discern Addison’s or Cushings, not the cortisol problems we tend to get, thus saliva is needed; b12 can go low if undiagnosed or poorly treated hypo; Magnesium, other minerals, plus D3 and D2 can go low with hypo; Remember to have them remove tourniquet when doing a blood draw for potassium; sex hormones like estrogen & progesterone tested seven days after ovulation i.e. days 10 – 20 / FSH & LH tested days 2-4 of cycle with day 3 being ideal / Testosterone, DHEA any time; MTHFR mutation plus hair testing for high heavy metals. See Direct Labs link below for hair testing.

**Have any suspicion of having thyroid cancer? The thyroglobulin test is a tumor marker (not the antibodies test–just the thyroglobulin. But take heart…there can be other reasons, including continued hypo, which can raise the thyroidglobulin, too.)


***After you get your results back, click HERE to read what patients have learned about interpreting lab results. It’s not about “being in the normal range”.


  1. Cell Science–very strange results that did not fit symptoms
  2. Quest–has too many “less than” results for ranges, which tell us nothing.
  3. Dutch saliva testing — often gives screwy results.


Below are lab facilities–NOT in any special order. 1-5 are for the United States (except for NY, NJ, RI, MA or MD), then you’ll see other countries below that. All of these can be used without a prescription (unless stated otherwise). NOTE: Ulta has worked it out with Massachusetts to allow you to order your own labs!

Note: Saliva is highly recommended to test cortisol, but blood for the other tests. Many of us stopped using saliva for sex hormones, as we have found them to be strange. Some facilities require a prescription for RT3, sadly, so definitely talk to your doctor about it if you have reason to believe it may be a problem. 

MyMedLab MY MED LAB packages designed specifically for readers of Stop the Thyroid Madness – After clicking on icon to the left, see the labs on the left of page. For adrenal testing, you will be choosing Diagnos Tech saliva for cortisol. Draws are done at any LabCorp facility around the US. Great facility!

Ulta Lab Tests

This is a great facility and I love the owner. You will see a variety of great labs specifically for those of you who value patient experiences and wisdom. NOTE: there is no saliva test yet with Ulta because I want them to carry ZRT and NOT Quest. I will update when they do. You will also see Men’s Hormones–but please take those results to men’s groups. Save an additional 10% off our everyday low prices on STTM Lab Tests with Promotional code ULTA41012

Direct Labs DIRECT LABS designed specifically for readers of Stop the Thyroid Madness…and includes Neurotransmitter testing, hair testing for heavy metals and other good labs. Patient do not recommend their saliva testing, as they now use Quest which has the terrible “less than” ranges. IMPORTANT NOTE about using this page: you will need to use scroll down bar just to the right of the red “Add to Cart” to view all labs they offer.  

Screen Shot 2015-06-29 at 10.40.05 PMTRUE HEALTH LABS offering direct lab testing since 2010, this facility has most of the STTM recommended labwork you need and want! Watch for discounts they give throughout the year, which will show up at the top of their page if there is one! You can even use code STTM to get an additional $5 off testing. You’ll see a friendly page just for labwork which patients know is key!!    NOTE: True Health is sadly using Genova for the saliva cortisol testing. Though the first three results will have ranges, it will mean a bedtime result with a less-than “range” or objective, and that is useless for us. We need that range. Healthy people fall at the bottom of any range. Just a warning. It’s up to you if you want to use them.

PRIVATE MD LABS have no STTM-recommended page on their website like the above facilities have, and you’ll have to search, sadly, but you can order the lab work recommended above, plus any others you feel you need and/or those results you want to share with your doctor.  

All the above are Affiliate links, which means there is a very small commission made to this website on each lab ordered and which helps pay for various costs associated for time spent creating this informational website. 

AUSTRALIA–they will send you the tests and patients find this facility the most reliable!


1) Approach your pharmacist and ask him to order a saliva cortisol test kit from Rocky Mountain Labs in Canada.

2) can ship saliva cortisol test kits to Canadians

3) MyMedLab ships saliva cortisol test kit to Canadians! But you need to use this number and tell them you saw this via STTM: 417-782-6169
