Thyroid Tests

Healthcare professionals use thyroid tests to check how well your thyroid is working and to find the cause of problems such as hyperthyroidism or hypothyroidism. The thyroid is a small, butterfly-shaped gland in the front of your neck that makes two thyroid hormones: thyroxine (T4) and triiodothyronine (T3). Thyroid hormones control how the body uses energy, so they affect nearly every organ in your body, even your heart.

Thyroid tests help health care professionals diagnose thyroid diseases such as:

  • Hyperthyroidism—when thyroid hormone levels are too high
  • Graves’ disease—the most common cause of hyperthyroidism
  • Hypothyroidism—when thyroid hormones levels are too low
  • Hashimoto’s disease—the most common cause of hypothyroidism
  • Thyroid nodules and thyroid cancer

Your doctor will start with blood tests and may also order imaging tests.

The thyroflex test is a non-invasive thyroid test which measures brachioradialis reflexometry and resting metabolic rate. The Thyroflex test identifies if your thyroid function is under or overactive or within optimal range. If you are already taking thyroid medication, the Thyroflex helps to ensure you are on the appropriate thyroid hormone replacement dosage with 98.5% accuracy.

Thyroid Treatment

For thyroid disorders stemming from the over- or under-production of thyroid hormones, both conventional and alternative treatments offer varied methods to try to restore hormone levels to their proper balance. Conventional treatments rely mainly on drugs and surgery. Alternative treatments attempt to relieve some of the discomfort associated with thyroid problems or to improve the function of the thyroid gland through different approaches ranging from diet supplements and herbal remedies to lifestyle changes and special exercises.

Treating hyperthyroidism requires suppressing the manufacture of thyroid hormone, while hypothyroidism demands hormone replacement. Conventional medicine offers extremely effective techniques for lowering, eliminating, or supplementing hormone production. Before deciding which treatment is best for you, your doctor will make an evaluation based on your particular thyroid condition, as well as your age, general health, and medical history.

Treating Thyroid Cancer

Thyroid cancer is usually initially treated by surgically removing either the cancerous tissue or the whole thyroid gland, a procedure known as a thyroidectomy. If the cancer has spread beyond the thyroid, any other affected tissue, such as the lymph glands in the neck, will also be removed.

Blood Tests

TSH BLOOD TESTS

The best way to initially test your thyroid function is to measure the TSH level in a blood sample. A high TSH level indicates that the thyroid gland is failing because of a problem that is directly affecting the thyroid (primary hypothyroidism). The opposite situation, in which the TSH level is low, usually indicates that the person has an overactive thyroid that is producing too much thyroid hormone (hyperthyroidism). Occasionally, a low TSH may result from an abnormality in the pituitary gland, which prevents it from making enough TSH to stimulate the thyroid (secondary hypothyroidism). In most healthy individuals, a normal TSH value means that the thyroid is functioning normally.

T4 BLOOD TESTS

T4 circulates in the blood in two forms:

1) T4 bound to proteins that prevent the T4 from entering the various tissues that need thyroid hormone.

2) Free T4, which does enter the various target tissues to exert its effects. The free T4 fraction is the most important to determine how the thyroid is functioning, and tests to measure this are called the Free T4 (FT4) and the Free T4 Index (FT4I or FTI).

T3 BLOOD TESTS

T3 tests are often useful to diagnosis hyperthyroidism or to determine the severity of the hyperthyroidism. Patients who are hyperthyroid will have an elevated T3 level. In some individuals with a low TSH, only the T3 is elevated and the FT4 or FTI is normal. T3 testing rarely is helpful in the hypothyroid patient, since it is the last test to become abnormal. Patients can be severely hypothyroid with a high TSH and low FT4 or FTI, but have a normal T3. In some situations, such as during pregnancy or while taking birth control pills, high levels of total T4 and T3 can exist. This is because the oestrogens increase the level of the binding proteins. In these situations, it is better to ask both for TSH and free T4 for thyroid evaluation.

Thyroid Function Tests

Thyroid disorders can be difficult to detect clinically, but thyroid function tests can assist in making a diagnosis. Measuring thyroid stimulating hormone is the first step. If it is abnormal, free thyroxine should be measured. A raised concentration of thyroid stimulating hormone with a low concentration of free thyroxine suggests hypothyroidism. A low concentration of thyroid stimulating hormone with a high concentration of free thyroxine suggests hyperthyroidism. Measuring thyroid auto-antibodies may help establish the cause of the dysfunction. Different assays can give different results, and tests of thyroid function may be affected by drugs and inter-current illness.

Thyroid Antibody Tests

The immune system of the body normally protects us from foreign invaders such as bacteria and viruses by destroying these invaders with substances called antibodies produced by blood cells known as lymphocytes. In many patients with hypothyroidism or hyperthyroidism, lymphocytes make antibodies against their thyroid that either stimulate or damage the gland. Two common antibodies that cause thyroid problems are directed against thyroid cell proteins: thyroid peroxidase and thyroglobulin. Measuring levels of thyroid antibodies may help diagnose the cause of the thyroid problems, It is important to understand thyroid problems For example, positive anti-thyroid peroxidase and/or anti-thyroglobulin antibodies in a patient with hypothyroidism make a diagnosis of Hashimoto’s thyroiditis. If the antibodies are positive in a hyperthyroid patient, the most likely diagnosis is autoimmune thyroid disease.
