Thyroid Testing. The Infamous Blood Test

Thyroid testing is done with a blood test, but how reliable is that test?

Dr. Andrew Dickens explains the problems with how thyroid function is tested. His point being that zero of the thyroid function takes place in the blood, so why is thyroid function tested with a blood test?

Dr. Dickens shares that for 80 years thyroid diagnosis was clinical: tired, constipated, dry skin, heavy menstrual cycle, foggy thinking, etc. Then in 1973, the present blood test came out and 80 years of clinical knowledge was thrown out. Previously the average dose was 3 to 4.5 grains of desiccated thyroid. Today rarely is this dose seen in the widespread population. He compares this blood test to buying a car based on gas in the tank.

Thyroid: Measuring the ‘unmeasurable’


In this article, Eric Seaborg shares the problems with adding T3 to T4 when treating hypothyroidism. The point I keep seeing brought up is how much better patients feel when taking a combination of T4 and T3. However, the reaction from the researchers is doubt that the patients really do feel better. You know: the “it’s all in your head” syndrome! I can’t tell you how many times I have heard this from doctors. Not to mention the total shock that you would have the nerve to ask for a medication other than levothyroxine! Because that is the standard of care for thyroid patients!!!!!

One researcher even states that the studies of combination therapy are flawed because the T3 was only given once or twice a day. What???

For those of us lucky enough to have a doctor who will give you a combination of T4 and T3, I am pretty sure you feel better than when you were taking levothyroxine alone.

I am totally amazed and disappointed in what doctors call care when dealing with thyroid patients. I can’t help but think that between the researchers and the pharmaceutical companies their only concern is profits, not how the patients are doing health-wise!



In this article, Dr. David J. Scott states Levothyroxine treatment did not significantly improve hypothyroid symptoms score or tiredness score in older adults with subclinical hypothyroidism, according to findings published in The New England Journal of Medicine.

Okay, so if younger people who take Levothyroxine have issues with symptom control when taking this hormone, why would older people be any different?

However, one should also question the ranges when doing thyroid testing, due to inconsistency in what is considered normal test results. treatment did not significantly improve hypothyroid symptoms score or tiredness score in older adults with subclinical hypothyroidism
