Hashimoto's Patients Have More Symptoms - TSH Misleading

By Paul on Mon, 01/05/2017 - 14:30

Feb of 2011: Johannes Ott and colleagues from Kaiserin Elisabeth Spital and Medical University of Vienna, Austria, report that women with higher levels of anti-thyroid antibody had a significantly higher number of symptoms, even though their levels of thyroid-stimulating hormone (TSH)-a measure of thyroid function-did not differ from TSH levels measured in women with lower antibody levels....

Another Example of Why Thyroid Blood Tests Make No Sense on T3 Treatment

By Paul on Sun, 13/09/2015 - 18:38

For people on T3-Only therapy, thyroid blood tests are often a pointless exercise. 

Thyroid blood tests can be helpful for people on just T4/levothyroxine meds and only then if they actually respond well to the T4.

For those on T3-Only (or mostly T3), signs and symptoms are really the best way to assess the dosing/effectiveness of the T3 treatment.

Blood levels of FT3, and FT4 can be very unrepresentative of actual thyroid hormone action inside the cells, and TSH is really not an indicator for many people on T3 treatment.

TSH Should NOT be The Gold Standard !!!!!!!

Thyroid Blood Tests - Reference Ranges are Not 'Normal Ranges'

By Paul on Wed, 11/01/2012 - 11:07

A laboratory reference range is the range in the unit of measurement for the given test that is usually provided with a specific test result. It is usually expressed as lowest level - highest level.

Keeping a record of all test results including the reference ranges can be very useful. However, references ranges are frequently misused.

Laboratories assess a wide population of people when calculating the reference ranges for TSH, FT4 and FT3. This is why they are population ranges. They do not provide the range that is necessarily where an individual's results need to be.
