Could anyone please tell me what your labs should look like if optimally dosed on Armour/NDT...? I know the TSH is deemed unimportant, as it's often suppressed when on drugs containing T3, but I am more interested in finding out what the FT levels should look like...or, more precisely, the FT3 levels. As far as I know, we are supposed to go to the lab 24 h after taking drugs containing T3. If that is correct, what should our FT3 levels look like when we go to the lab, when we are optimally medicated...?
Or, in case we don't need to wait 24 hours before going to the lab...what should your FT3 levels look like right after you've taken NDT?
I realise there are no exact rules, but I'd nonetheless appreciate some guidance on this.
In an article someone posted the other day, T3 will peak around five hours after taking the day's dose. I guess if that is what you want to know....... but perhaps you'd rather see how low it goes rather than how high it is. To tell you the truth I don't know if it would be the same if you are taking T3 only or T3 with T4? Normally FT3 should be in the upper part of the range given but also according to how you feel I would think.
Dr. Lowe is the only doctor I have heard of that took T3 only. You could go to the website and see if anything has been stated regarding your question.
Right now, I take Armour Thyroid (5 grains daily). This is what my latest labs looked like, about 24 h after taking any Armour (labs from 21/10 2015):
FT4 1.12 (ref 0.7-1.4)
FT3 2.92 (ref 1.7-3.7)
TSH 0.01 (ref 0.4-4.0) suppressed
What I want to know, more than anything, is if this indicates that my FT3 levels are suboptimal and, if so, how to raise them...raise Armour? Or switch to an NDT drug without cellulose?

They look good, Anna and probably should be with such a high dose. The conversion looks fine. There is room if you feel the need. I wonder if taking T3 and reducing Armour would be helpful. I haven't read your history/profile. Maybe you have already tried other things.
I think you lose as much as you gain each day when you have reached your optimal dose. It's like adding a teaspoon to a bowl of water that evaporates a teaspoon a day.
Anna69, when optimally dosed, FT3 will usually be in the top third of range. Clarebear took 2.5 grains a couple of hours before a blood draw. FT3 was 15 but was usually around 5 24 hours after last dose.

OK, so just to be clear about this: should we take meds containing T3 BEFORE going to the lab??? I always waited until afterwards, and always made sure I had not taken any thyroid meds for 24 h when having blood drawn.
Anna69, ALL thyroid meds, T4 and T3, should be taken after the blood draw. You've been doing it the right way by leaving 24 hours between last dose of NDT and blood draw.

Can someone explain this concept to me? All these years my doctor has never told
Me don't take your meds 24 hours before a draw.
How does this work? If we don't take the meds the labs will just say we need more meds and thyroid function is off. Aren't we suppose to be checking if the dose we are on is doing its job by getting blood drawn on the meds?
I am glad you asked that question, because I am also beginning to find it confusing...the main reason my doctor said Armour did not seem to be working optimally for me was because I had blood drawn 24 hours after taking my meds, and my FT3 levels were about mid-range...
What I have been told in the past is that the T3 in drugs like NDT and synthetic drugs like Cytomel will raise our FT3 levels so much that it will look like we are overmedicated. I just don't know if that is correct, or if it is like you say; that is, that in order to know how a given drug works for us (in terms of absorption), we need to get blood drawn on the meds...? After my own experience with Armour, I'd be tempted to say you're right...if T3 has such a short half-life (I have read 12-24 hours), most of it is likely gone from our bloodstream 24 h after taking meds...
