Optimal Thyroid Essentials Test (Blood Spot Testing)

The Optimal Health Thyroid Essentials test is an easy to use at home blood spot test kits that analyzes the main biomarkers that affect optimal thyroid function. 

As part of the endocrine system, the thyroid, and the chemical hormones it creates affect nearly every organ in the body in some way.  Though 20 million Americans suffer from thyroid conditions every day, according to the American Thyroid Association, roughly 60% go undetected. 

Four key biomarkers TSH, T3, T4, and TPOAb provide a complete picture of thyroid health and function.

Related Symptoms

The underactive thyroid fails to produce adequate T3 and T4 (hypothyroidism).

This may result in:

  • Fatigue
  • Weight gain
  • Depression
  • Muscle and joint pain
  • Cold sensitivity
  • Hands and feet always cold
  • Concentration difficulties
  • Brain fog   
  • Dry hair and skin 
  • Heavy menstrual periods
  • Constipation 
  • Lower heart rate
  • Neck swelling from an enlarged thyroid 
  • Bradycardia (heart rate below 60/bpm) 


    The overactive thyroid (hyperthyroidism) produces excess T3 and/or T4.

    As a result, the following may occur:

    • Rapid weight loss
    • Increased appetite
    • Rapid heartbeat
    • Anxiety/irritability
    • Hands trembling 
    • Sweating
    • Menstrual changes
    • Heat sensitivity
    • Frequent bowel movements
    • Neck swelling from an enlarged thyroid
    • Muscle weakness/fatigue
    • Sleeping difficulties
    • Thinning skin
    • Brittle hair
    • Tachycardia (heart rate over 100/bpm)
      Biomarkers Measured

      TSH

      Thyroid-stimulating hormone created in the brain signals the thyroid gland to produce triiodothyronine T3 and thyroxine T4.  Testing TSH levels is fundamental in identifying thyroid function

      Normal range is 0.5 - 3.0 μU/mL

      FT3

      Free t3 tests measure freely circulating T3 within the blood.  T3 helps regulate major body functions including metabolism, heart rate, temperature, and heart rate

      Normal range is 2.4 - 4.2 pg/mL

      FT4

      Free T4 is transported directly to body tissues and produced in higher quantities than T3.  T4 gets converted to T3.

      Normal range is 0.7 - 2.5 ng/dL

      TPOab

      TPOAbs are unwanted antibodies made by the immune system that suppress thyroid function.

      Normal range is < 150.0 IU/mL

        Thyroid Test FYI

        The butterfly-shaped thyroid gland located at the base of the neck secretes important hormones T3 and T4 and works to regulate a multitude of functions within the body including metabolism, heart rate, temperature, digestion, brain development, muscle control and maintenance of mood and bones.  As part of the endocrine system, the thyroid, and the chemical hormones it creates affect nearly every organ in the body in some way.  Though 20 million Americans suffer from thyroid conditions every day, according to the American Thyroid Association, roughly 60% go undetected. 

        Four key biomarkers TSH, T3, T4, and TPOAb provide a complete picture of thyroid health and function.

        TSH, or thyroid-stimulating hormone is produced by the pituitary gland and transported to the thyroid gland itself where it will stimulate the creation and regulation of triiodothyronine (T3) and thyroxine (T4), primary thyroid hormones.  The body’s immune system further creates Thyroid peroxidase autoantibody TPOAb that works to suppress the production of thyroid hormone.

        How Thyroid Biomarkers Work

        Thyroid hormones are an integral part of cellular activity in nearly every area of the body, and dependent on healthy thyroid function.  Understanding the interplay between each of the thyroid hormones, TSH, T3, T4, and the immune system antibody TPOAb is important in thyroid testing and symptom management. 

        When T3 and T4 levels drop, the pituitary gland secretes TSH, which in turn stimulates the thyroid gland to create more primary thyroid hormones. When T3 and T4 levels increase, the pituitary gland secretes less TSH, which reduces hormone production.  When T3 and T4 reach organs and tissues, increased energy and cellular growth occur.  If too much T3 and T4 is present, hyperthyroidism may occur.  When the thyroid is underactive, insufficient amounts of T3 and T4 are produced causing many of the symptoms hypothyroidism.  In the case of autoimmune-related thyroiditis, TPO is attacked by the body’s own immune system and circulating TPOAbs levels will be elevated.
