Anderson, 2020: Thyroid hormones and atrial fibrillation
Atrial fibrillation is a cardiac rhythm disorder that significantly elevates the risk of stroke as well as stroke severity. Thyroid hormone excess caused by hyperthyroidism is often named as one of the risk factors for atrial fibrillation. However, it does not require excess thyroid hormone above the reference range to elevate risk of atrial fibrillation. … Continue reading Anderson, 2020: Thyroid hormones and atrial fibrillation
The thyroid gland is a T3 shield. Defend the unshielded.

Think twice about cancelling patient-pay Reverse T3 tests
At the end of January 2020, Alberta Precision Laboratories established a new policy of cancelling patient-pay Reverse T3 (RT3) tests on standard laboratory test orders. One memo in circulation explains the justifications based on RT3 silence in the 2012 and 2014 thyroid clinical guidelines. The memo was issued by Dr. Hossein Sadrzadeh, Section Chief, Clinical … Continue reading Think twice about cancelling patient-pay Reverse T3 tests

For many decades, scientists have been studying the effect of thyroid hormones in promoting cancer proliferation. Confusion and contradictions often arise in "cancer & thyroid" research reviews because the relationship between cancer and thyroid hormones is very complex. For example, a recent review of science since the 1940s attempted to reclassify research findings under poorly … Continue reading Cancer scientists point finger at T4 & RT3 hormones
