Which lab tests reverseT3?

[DizzyD]

Does anyone know if Medichecks do reverse T3 testing? If they don't what are the options?

Thank you in advance

Kind regards to all who pass by this way!!

As far as I am aware Medichecks have stopped their reverse T3 testing, whether that is temporary or permanent I don't know.

However, why do you want to test rT3? It really is a waste of time and money. It's an expensive test and takes around 3 weeks or so to get the result.

Reverse T3 can be caused by many things, only one of which is to do with the thyroid and that's when there is an excess of unconverted T4 and your FT4 and FT3 results are going to tell you that - if FT4 is high and FT3 low then T4 is not converting to T3 well enough.

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.

Other 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.

Thank you Susie I was reading one of your previous posts from a year ago about reverse T3 being a pointless test them you sent the same post to me. Enlightening to read why reverse T3is considered as being a waste of time and money. Having it explained makes sense so decided not to go down this path. Basically it's my adrenals that is causing many problems.

Sincere thanks....Have a rewarding day
