Thyroid dysfunction is notoriously under-diagnosed,
yet a simple home-test explains a wide variety of symptoms
and determines the effects of nutrient deficiencies or toxic
elements on thyroid function—key for optimal performance
and body-composition.



Thyroid disease or dysfunction can explain a wide variety of symptoms, yet it is notoriously under-diagnosed. The Colorado Thyroid Disease Prevalence Study published in 20001 found that 9.9% of the study population consisted of people who were not being treated for thyroid problems yet had abnormal thyroid function test results, suggesting that their thyroid disease was previously undiagnosed. This study also found a significantly greater incidence of thyroid dysfunction in women than in men in each decade after the age of 34.

Thyroid function can be affected by nutritional deficiencies, particularly iodine and selenium, and by environmental exposure to bromine, arsenic, selenium, mercury and cadmium. We are all, to varying degrees depending on our dietary choices, our supplementation routine, or our lifestyle, exposed to the elements iodine, bromine, selenium, arsenic, mercury, and cadmium. These elements are present in the food we eat, air we breathe, and water we drink, as a result of pollution as well as natural occurrence, and are generally tasteless, odorless, and impossible to detect without sophisticated instrumentation.

An easy-to-do home collection bloodspot and dried-urine test for:

Thyroid Stimulating Hormone (TSH), Free Thyroxine (T4), Free Triiodothyronine (T3), Thyroid Peroxidase Antibody (TPO), Thyroglobulin, Thyroxine (T4), Iodine, Selenium, Bromine, Arsenic, Cadmium, Mercury, and Creatinine

Advantages of a Simple Blood Spot Test

  • No phlebotomist or centrifugation required, therefore less expensive and more convenient than conventional blood draws
  • Nearly painless finger stick is used to collect the few drops of blood required 
  • Private and convenient for both patient and healthcare provider—collection at home or provider’s office
  • Hormones and other analytes are stable in dried bloodspot at room temperature for weeks, allowing for worldwide shipment
  • Safe handling and transport of samples, as infectious agents are destroyed by drying.
