I am at work at the moment so I don't have access to my full labs but I do have some the of the numbers I saved in my phone.....
TSH - 2.7 ulU/mL (.45 - 4.5)
Free T3 - 3.9 pg/mL (2.0 - 4.4)
Free T4 - .91 ng/dL (.82 - 1.77)
Reverse T3 - I can't remember the exact number but when I did the calculation my RT3 was low/not an issue. *Also, my antibodies were also good not an issue...
I was told that I might be pooling but the fact that my RT3 was not an issue I'm just wondering if it's just my FT4 being out of whack..
I do find myself having a lot of brain fog/memory issues and I have researched that T4 affects these functions.
thoughts???
Yeah, you're kind of on the right track with the RT3 and FT4 ... T4 converts to T3 and RT3. If something is causing T3 to pool then the demand increases for T4 to convert to higher rates of RT3. However, when FT4 is only at 10.5% of the reference range (as in your case), the amount of RT3 will reflect and be relative to FT4; resulting in lower serum levels.
This is where you will see some people take T3 only (Cytomel) treatments, allegedly to "flush" out RT3. What's being overlooked is that Reverse T3 isn't some foreign toxin needing purged, it is counter reaction marker to conserve resources when the body has various imbalances and/or is in a state of injury or sickness.
Also, consider this as you're moving forward on thyroid treatment ... As noted above, T4 converts to T3 (and T2, T1). In a normal functioning thyroid we might look at T4 as being the reserves, which feeds downstream with conversion to the more highly potent T3. For energy, metabolism, ATP, it would be fair to say that FT3 reaching the cells in the body is truly where the rubber hits the road. In an optimal arena, many including myself might say that an optimal FT3 serum level is somewhere in the 50%-to-80% area of the respective reference range.
Yours is at 79% of the reference range!!
So to conclude, what would be accomplished with any thyroid treatment if your FT3 is already at the TOP of the range? Again, it's great to have an equal balance of T4 and T3, with low conversion to RT3, but ultimately the real results are with how efficient FT3 is working in the body (?). Like testosterone, the other variable is making sure there's an optimal amount of the hormone in the system .. In your case the serum level is fine. I think you may want to look deeper into areas like iron, ferritin, the adrenals, electrolytes, and variables that could impact T3 and cause it to pool. If you have a complete set of labs from CBC's to metabolic, post it up and let's talk more ...
