Thyroid problems are conditions affecting the thyroid gland's ability to produce hormones that regulate metabolism, energy, and growth. They are caused by insufficient or excessive production of thyroid hormones including TSH (thyroid-stimulating hormone), T3 (triiodothyronine), and T4 (thyroxine), or by environmental factors like elevated fluoride that interfere with thyroid function. The Fluoride Serum/Plasma test is the most important supplementary test for identifying environmental factors that may be disrupting thyroid hormone production.

Thyroid problems are caused by insufficient or excessive production of thyroid hormones (TSH, T3, and T4) or by factors that interfere with thyroid function. Autoimmune conditions like Hashimoto's thyroiditis and Graves' disease attack the thyroid gland, while environmental toxins such as elevated fluoride from drinking water, dental products, and certain medications can disrupt hormone production. Iodine deficiency, thyroid nodules, inflammation, and pituitary gland disorders can also cause thyroid dysfunction by affecting hormone regulation and synthesis.
The Fluoride Serum/Plasma test is the most important supplementary test for thyroid problems when standard thyroid hormone panels show persistent dysfunction despite treatment. This test measures fluoride levels in your blood to identify whether environmental fluoride exposure is interfering with your thyroid's ability to produce hormones effectively. Elevated fluoride can contribute to hypothyroidism by blocking iodine uptake and disrupting thyroid enzyme function. While standard TSH, T3, and T4 tests remain essential for initial diagnosis, the fluoride test helps uncover hidden environmental factors that may be preventing your thyroid from functioning properly, especially if you have symptoms that do not improve with conventional treatment.
You should get tested if you experience unexplained weight changes, persistent fatigue, sensitivity to cold or heat, hair loss, dry skin, or mood changes like depression or anxiety. Testing is also important if you have irregular menstrual cycles, difficulty concentrating, muscle weakness, or a family history of thyroid disease. If you live in an area with fluoridated water or use fluoride dental products frequently and experience thyroid symptoms, consider getting a fluoride test along with standard thyroid hormone testing to identify potential environmental contributors to your condition.

What this means
Your fluoride level is elevated above the optimal range, which may indicate overexposure from drinking water, dental products, or other environmental sources. While not immediately dangerous, sustained high levels can lead to dental fluorosis, bone problems, and other health issues over time.
Recommended actions
Test your drinking water for fluoride content and consider using a reverse osmosis filter if levels are high
Switch to fluoride-free toothpaste or reduce the amount of fluoride toothpaste you use
Limit consumption of black tea and processed foods that may contain added fluoride
Retest in 3-6 months after making changes to your fluoride exposure sources
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
