Ratio reverse T3 and T3 overactive immune system
Rt3/TT3 index (write code REVT3R RATIO from serum in other analyses)
The ratio can only be determined at the lab as T3 and REVT3 test, we cannot determine this this ratio afterwards. So only when this product is ordered you will get this ratio reported.
In this test, the ratio TT3/RT3 is calculated.
How can you measure if you have an overactive immune system?
Bylooking at the ratio between your T3 and rT3 blood levels. So when you have too much rT3 in proportion, you have an active immune system (or extreme emotional stress) and your other organs are not getting enough energy to thrive and feel good.
rT3 is an inactive form of the T3 hormone.
A sluggish thyroid is an under-recognized problem in Western medicine.
In fact, most laboratories look at the amount of TSH and T4. But usually reverse T3 (rT3) is not measured (T3 also often not measured). Your body always makes rT3 to get rid of excess T4. If more energy is required elsewhere in the body, rT3 production goes up. For example, due to stress or an active immune system.
If rT3 is too high, the body will ensure that the energy consumption is adjusted by making the thyroid gland work more slowly.
It may therefore be that your TSH is high-normal and your T4 normal. Your doctor then says there is nothing wrong with your thyroid hormone, but maybe your T3, your active thyroid hormone, is low and your reverse T3 is high. If so, something is definitely wrong.
The causes of too high a rT3 level can be:
- Chronic stress
- Intestinal problems (leaky gut)
- Low iron or Hb
- Inflammation(also low-grade inflammation caused by food intolerance)
- Low vitamin B12 status
- Low vitamin B6 status
- Low selenium
- Low vitamin D content
- Consequences of yo-yo dieting
- MTHFR gene mutation
It is not always a solution to work with thyroid medication alone, the other problems and lifestyle need to be worked on as well.
In this blood test, reverse T3 (rT3) and total T3 are reported and also the ratio calculated
Delivery time: Reverse T3 is a specialist test and it can take up to 1 to 2 weeks for the results to come in. If you have ordered other tests you can request a partial result after one week.
