Biochemical Bigotry – Enforcing Normalised Thyroid Lab Test Results is Harmful to Health

Here is another great article about the flawed use today of thyroid laboratory tests and lab reference ranges.

It talks about how endocrinologists and doctors want thyroid patients’ lab results to conform to their standard lab ranges. 

The article illustrates how this is harming the health of many thyroid patients.

I have written a lot about the poor use of thyroid lab testing – this speaks to this point totally.

Here’s the article:

It is a great article by Tania S. Smith.

In particular, those patients who have any T3 medication in their doses are often forced to conform to stupid rules of having TSH in a certain range, and FT3 not close to the top of the range and even having the desired range of FT4 (even when this makes the person feel ill).

Being on any T3 medication, even a small amount combined with T4 begins to make the thyroid lab ranges too restrictive. The ranges were developed based on healthy people, or those on T4 therapy only. They often do NOT apply to people on T3 in combination, OR on T3 alone. There are good reasons for this. Reasons that most  endocrinologists have not considered.

On T3 alone, in particular, people often have to be well over the top of the range that making use of ranges to dose medication is a joke. This is because these people have very little T4 and there is no on-going, hidden T4 to T3 conversion occurring in their cells. See my blog for more information on this.

I believe for all medications symptoms and signs ought to be the predominant method of assessing thyroid dosage efficacy. Thyroid lab test results must include FT3 because it is the most important measure but these results should only be used as an indication of whether the numbers are changing correctly with dosage changes.

Thyroid lab results should not be used to control patients’ medication levels, as this is ‘bio-chemical bigotry’ as Dr. Smith has written about so eloquently.

The current approach is definitely harming the health of thyroid patients.  It is a very fascist way of treating thyroid patients. I really do mean that.
