Question about reverse T3 and Thyroid panels.

[Unite_To_Fight]

So, I have finally gathered the funds, to be able to purchase a full thyroid panel test and any vitamins and other tests that are recommended in relation to the thyroid.

However, I was curious on how crucial it is to get the reverse T3 tested? as choosing to include this option in the testing kit I was interested in (at blue horizon) bumps up the price significantly.

Could I also get a reminder / suggestion, on what I need to test for specifically, thank you.

Don't waste your money or time. This is an expensive test that takes a long time to be returned and doesn't tell you anything that the full thyroid panel can't.

If reverse T3 level comes back high, the test can't tell you why it's high.

Reverse T3 can be high for many, many reasons, only one of which has anything to do with the thyroid and that is when there is an excess of unconverted T4, and testing FT4 and FT3 will tell you this.

Things that can cause high reverse t3 include selenium or zinc deficiency, cortisol issues, stress, dieting, chronic illness, inadequate or low iron, chronic inflammation, high cortisol, or liver issues and any other chronic health issues. and probably several more things.

Conditions that contribute to increased Reverse T3 levels include:

· Chronic fatigue

· Acute illness and injury

· Chronic disease

· Increased cortisol (stress)

· Low cortisol (adrenal fatigue)

· Low iron

· Lyme disease

· Chronic inflammation

Also selenium deficiency, excess physical, mental and environmental stresses. Also Beta-blocker long-term use such as propranolol, metoprolol, etc. Physical injury is a common cause of increased RT3, also illnesses like the flu. Starvation/severe calorie restriction is known to raise RT3. Diabetes when poorly treated is known to increase RT3. Cirrhosis of the liver. Fatty liver disease. Any other liver stress Renal Failure. A fever of unknown cause. Detoxing of high heavy metals.

That is very interesting and informative, thank you for the detailed response and explanation, really glad I decided to ask first, rather than just jumping into a purchase.

I will ensure that I get all blood markers you mentioned tested as soon as possible and get the results posted onto the forum for feedback and opinions.

Once again, I appreciate your response with all this information.

Thanks Susie!
