Accurate Thyroid Function Tests

Accurate Thyroid Function Tests

Article 004# – The Lucy Rose Clinic

The accurate diagnosis of your thyroid function is imperative if you want to lead a thoroughly healthy life. So how do you find out what’s really going on?

When you don’t feel well, you go to your health professional and explain your symptoms to them. They often ask some questions and then run some blood tests. For other conditions this is usually a reasonably accurate summary of your health picture, however this is not the case with thyroid diagnosis. It is definitely not black and white. This means that the majority of patients with low thyroid function are misdiagnosed and told they are fine, and leave their appointments feeling frustrated, disheartened and despairing. We hear testimonies of patients having gone through this time and time again in clinical practice.

The current blood testing methods simply do not tell the whole story.

If patients still have thyroid symptoms when their TSH levels are normal, how can the blood test be correct? The symptoms show otherwise.

75 % of your thyroid hormone is in the skin, muscle and brain, so how then is it possible to get an accurate measurement on thyroid function from your blood? The other issue is that TSH, the standard blood test used to establish thyroid function doesn’t take into account that you may have ample thyroid hormone in the blood, giving a good healthy reading, but that it cannot tell you if the hormones are working well or not. In short thyroid hormones are not active in the blood.

The Standard Blood Tests miss many cases of Thyroid Disease. TSH markers are different around the globe because it cannot be decided where they should be. In 1971, in his speech at the Medical Society’s Transactions Dr. R.I.S. Bayliss, a famous Endocrinologist (one of the most renowned endocrinologists in the USA on blood tests) was asked after many decades of treating thyroid conditions how he could tell when a patient had adequate thyroid replacement.

“I am often asked how the correct dose of thyroxine is determined. The answer is clinically by the patient’s pulse rate, his sense of wellbeing, the texture of his skin, his tolerance of cold, his bowel function, and the speed with which his deep tendon reflexes relax.” Is thyroid not the hormone capable of raising the constitution and well-being of the patient? Anyone can be brought up to the top of their constitutional capabilities when tested adequately for thyroid hormone. This would only be done by clinical assessment, not blood tests; there is no relation between the signs and symptoms of low thyroid disease, the TSH, or the other related blood tests”.

Clinical Assessment is a MUST if you are to get the correct diagnosis on your thyroid function. This means using all of the following to establish true diagnosis:

  1. ALL the blood work (specifically reverse T3, T3U, and thyroid antibodies)
  2. Urinary Iodine Test to establish whether or not you have enough iodine. The thyroid cannot work at all without the right amount of iodine.
  3. Thyroflex test (reflex test) Ref: 80-120 m sec Relaxation Phase of Tendon Reflex. Numerous studies have shown that this is a more accurate measure than serum blood tests, and is imperative to assess for accurate diagnosis.
  4. Basal Body Temperature 36.5 Basal Metabolic Rate (BMR). Resting temperature measured on waking, before movement. Anything under 36.5 indicates low thyroid function.
  5. In depth assessment and elicitation of presenting symptoms. The body will tell a skilled physician what is wrong with it by careful evaluation of the symptom picture.



“I had seen lots of doctors and been to every specialist under the sun and was always told that my blood tests were normal and that there was nothing wrong with me. I kept saying, why am I so tired then, why can’t I lose any weight even though I eat like a rabbit? It wasn’t until I had the thyroflex test done that I realized the severity of my condition. It was the first time anyone had told me what was going on. My thyroid function was terrible. I cannot begin to tell you the relief I felt when they told me! I now know WHY I have been feeling the way I have and I am now starting to feel the best I have ever felt in my life thanks to The Lucy Rose Clinic and the treatments they have been giving me.” Julie, Sydney
