Reverse T3 Test
In times of stress, the body may need to conserve energy. Since thyroid hormone acts like our internal thermostat, thyroid hormones may be suppressed in times of stress. One way this is done is by converting the thyroid hormone T4 into an inactive form of the active T3 hormone called reverse T3. This lowers the amount of available active T3 which can lead to hypothyroid type symptoms.
Since it is not standard to check for reverse T3 levels, your lab results may look normal but are still having low thyroid type symptoms. Instead of identifying the underlying stressor, most are prescribed the standard thyroid replacement hormone.
What’s Being Tested:
- Reverse T3
