Elevated Reverse T3 correlates BEST with hypothyroidism, NOT elevated TSH, & can be cause by mercury

Elevated levels of TSH (thyroid stimulating hormone) in the blood are NOT the best way to diagnose hypothyroidism as modern medicine has been led to believe according to a yet-to-be-published study by Davis Lamson, ND.
The thing that correlated best with a clinical diagnosis of hypothyroidism—that is, a diagnosis made on the basis of medical signs and patient-reported symptoms rather than lab tests—is elevated levels of Reverse T3 thyroid hormone.
Reverse T3 blocks T3 thyroid receptors which reduces metabolism.
Results of Dr. Lamson’s study were described by Jonathan Wright, MD in an interview he did with Joseph Mercola, DO.
Dr. Lamson works with Dr. Wright at Dr. Wright’s clinic.
By blocking T3 receptors, Reverse T3 is natures’ way of protecting us from starving so quickly by reducing metabolism.
But that’s not all.
They also found that in people with elevated Reverse T3 levels, that 95% of the time, these people had elevated levels of mercury or lead or cadmium or other heavy metals, and when they got rid of the mercury, lead or other heavy metals, levels of Reverse T3 returned to normal.
This is of interest to me because I recently found out that I am suffering from mercury toxicity, and I have had thyroid problems, feeling cold and having a low body temperature, as low as 96.3°F over several months when my symptoms of mercury toxicity were at their worst in the Fall of 2015.
50% of People Clinically Diagnosed with Hypothyroidism Had Elevated Levels of Reverse T3;
12.5% Had Elevated TSH
Davis Lamson, ND looked at what parameters correlated best with clinically diagnosed hypothyroidism and found that about 50% of people clinically diagnosed with hypothyroidism had elevated levels of Reverse T3, whereas only about 12.5% of these people had elevated levels of TSH notes Dr. Wright.
(Dr. Wright notes that the 12.5% might not be accurate because he did not have Dr. Lamson’s study in front of him.)
The paper has not yet been published based on an email correspondence with Dr. Lamsom.
95% of People With Elevated Reverse T3 Found to Have Elevated Levels of Mercury, Lead or Other Heavy Metals
Dr. Wright said that at his clinic, Tahoma Clinic in Tukwila, Washington, US, they found that in the people with elevated Reverse T3, that if they do a heavy metal challenge test with EDTA and DMPS, 95% of the time they find out that these people have elevated levels of mercury or lead or cadmium or other heavy metals, and that when they get rid of the mercury or lead or other heavy metals, levels of Reverse T3 return to normal.
Study from Norway Found Elevated Reverse T3 in Workers Exposed to Low Levels of Mercury Vapors
A study from the National Institute of Occupational Health in Norway published in 2000 also found higher levels of Reverse T3 in workers (chloralkali workers) exposed to low levels of mercury vapor for an average of 13 years compared to referents (268 pmol/liter in workers exposed to low mercury vapor versus 240 pmol/liter in referents.)

Mercury or Lead Challenge Test May NOT Be the Best Way to Do It
Note: In people with mercury toxicity, a mercury challenge test can make people feel WORSE because it liberates mercury in the body as noted by Chris Shade, PhD from Quicksilver Scientific. He developed the Mercury Tri-Test which compares levels of different forms of mercury in the hair, blood and urine.
A Better Way to Detox Mercury, Lead and Other Heavy Metals
Chris Shade, PhD, who founded Quicksilver Scientific, has also developed a better way of getting mercury out of your body—detoxing mercury, lead and other heavy metals which does not use DMPS or DMSA.
There are numerous videos of Chris Shade on YouTube describing why his detox method is better than using DMPS or DMSA.
One of these videos, which is 5-minutes long, is embedded below.
