Armour supplies you much less T4 than either Synthroid or a functioning gland would supply, so both TT4 and FT4 should be below the reference range. The reference range is determined for an UNMEDICATED, ASYMPTOMATIC population. It represents a ONE-SIGMA variation above and below the mean for a skewed distribution. All that means is that you need to interpret (and maybe calculate) some things for a person diagnosed with hypoT and taking medication. The reference range definitely does not mean anything is normal. It just gives you a range to compare to from a euthyroid population that does not take any thyroid medications. Many people on Armour do not feel well until the TSH is below the reference range and FT3 is at the upper end. That is " normal " for them. Now for the exception. I would still want to compare FT3 to TT3, or equivalently and cheaper to measure, FT4 to TT4. That would show whether you have a binding disorder, even if both the total and free were in the reference range. The ratio is what is critical. If your TSH is at or below the bottom of the reference range, and your frees and ratios are OK, then I would look at RT3. That is what Roni has struggled with. It is relatively rare, but it is another way that most of the tests can be in the reference range, but you still have hypoT symptoms. About half of the T4 you take is turned into RT3 instead of T3. If that percentage increases by even a small amount, the RT3 actually blocks the activity of T3. It not only has almost no activity of its own, it fills T3 receptors in the cells and prevents T3 from activating the metabolic pathways. 's syndrome, which we disparaged a bit recently, claimed that RT3 itself promotes the excess conversion of T4 to RT3. Thus, it creates a " locked " feedback loop once it starts. Several studies have shown this to be impossible, but something can keep the RT3 in excess for a long period. Adrenal failure can do it. So can starvation. Roni doesn't seem to have either condition, so something else must be going on. We just know it helps for the extreme cases to avoid any source of T4. Some do well on Armour, since it is mostly T3. You might be in the same boat. Chuck Quote Link to comment Share on other sites More sharing options...
Guest guest Posted September 11, 2010 Report Share Posted September 11, 2010 Once the RT3 showed up and I was switched to T3 only, the RT3 started gonig down and I started to feel better. They tried to add back some T4 to hopefully stabilize me since T3 is very short acting and requires multiple dosing. It didn't work. I got sick as a dog each time they tried it. So far things are better on the T3 only. <>Roni Immortality exists! It's called knowledge!

Guest guest Posted September 11, 2010 Report Share Posted September 11, 2010 Chuck - so what you are saying, I think, is that having a flagged low Free T4 on Armour is not an uncommom issue?

Guest guest Posted September 11, 2010 Report Share Posted September 11, 2010 , part of what I was saying is that analysis and opinions aren't said in plain English here. I've been struggling to understand the thyroid and all of it's ins-n-outs and reading something like that makes me skim through it because it's so hard to understand that I give up on it. I would consider myself an above average person on intellect, read a lot,etc. I can't even imagine how it would be for someone else to read that who isn't as experienced or perhaps as well read as I am. Plain not fair to expect the average person to understand what he's trying to say below. Even though the information might be valuable, I can't understand what is being said.

Guest guest Posted September 12, 2010 Report Share Posted September 12, 2010 I just read it again looking for places where someone not versed in science might well be confused and I do in fact see a few. But there is a heck of a lot of good info there and I'm sure Chuck would be more than willing to clarify the few locations where you may be thrown off track. I would even be willing to have a shot at it myself as I don't find the terms totally foreign; however since I'm not a scientist or any kind of professional I might screw it up. In any event Chuck is about the most helpful person you will ever find so don't hesitate to ask for clarification.

Guest guest Posted September 12, 2010 Report Share Posted September 12, 2010 I agree - ANY medical info requires a thorough reading regardless of who writes the info - that is just part of the details. I understand completely upon clarification, AND I had a good handle on the original answer. I simply wanted clarification then I could take the comment as a good one, or if I disagreed, I could throw it in my mental trash bin. With most info, one needs the details - you can tell me I am 'sick' or you can tell my the 'whys' but it all boils down to details. I have read many medical documents and picked out info that even a doctor skipped over but it DOES take several times of reading to see what the intent was - I am not a doctor so I do not 'think' like one but I have had tons of experience in reading documents, medical, governmental, corporation - and it is all in the wording. Sometimes I think it is done on purpose just to confuse the general population but that is a whole different subject ))) > > Sure; but as I said Chuck will clarify.

Guest guest Posted September 13, 2010 Report Share Posted September 13, 2010 For the most part it's not really from an intent to confuse us ordinary mortals; rather it's in order to be more clearly understood by professionals in the field. The language in science and medicine [as well as other] fields often presents a much more rigorous definitions of terms which aid in presenting very complex subjects with greater clarity to those who " speak the language " .

Guest guest Posted September 18, 2010 Report Share Posted September 18, 2010 It looks to me like your FrT3 is too low (should be at top of range) RT3 is too high (It's blocking your receptor cells from getting the proper hormone. This happens when your body for some reason stops converting T4 to T3 and makes too much Rt3. It happened to me too, while I was on Armour, which changed their formula and created this problem with lots of people. In order to reverse this you would need to take T3 only and start at a very low dose - 5 mcg 2xday and then increase as your body calls for it. Google Cytomel dosing on line and you will see how to do it, if your doctor won't treat you with the T3 only. Any T4 you put into your body now will just continue to make the RT3, and you won't be getting what you need for health. (There is a generic Cytomel called liothyronine) If you get that one you have to be very careful that the pharmacy only gives you the one that you start with and doesn't change brands because it messes up your dosing. Because Cytomel (liothyronine) is short lived you will need 4 or 5 doses daily at some point. However that is still far superior than being sick. TPO is a Thyroid Peroxidase Antibody Test. Yours appears normal. <>Roni Immortality exists! It's called knowledge!

Guest guest Posted September 19, 2010 Report Share Posted September 19, 2010 Duffy, Thanks for including all the reference ranges. Your doctor is ruling out a number of related hormone conditions, some not directly connected to the thyroid. I would suggest you review the meanings of these results with your doctor. You might want to first narrow down the questions by looking at a standard description of what lab tests mean. A good example is at: http://www.labtestsonline.org/ In addition, I'll comment on some selected results. You wrote: > > ... January 29, 2010 LAbcorp.

This is a precursor for several hormones, which gradually drops off as we age. It also fluctuates. People have speculated that replacing DHEA helps with various hormone related functions, but there is scant evidence to support this.

The RT3 is in the middle of both ranges, and those were both old readings, when the Armour dose was low, and there was still some T4 coming from the thyroid itself. While the FT3 readings could be higher, I would want to compare the frees (FT3 and FT4) with their corresponding totals (TT3 and TT4).

Guest guest Posted September 19, 2010 Report Share Posted September 19, 2010 Yes, it would. I think since there was a small amount of T4 coming in that the FT3 level was too high. I know how sick I was with a level about 2/3-3/4 up the range. Once I switched to T3 only each time they tried with a very small amount of T4, I would get sick agian, and had to stop it. I really wished I could have some of the T4 because it's more stabilizing, but I couldn't do it. <>Roni Immortality exists! It's called knowledge!
