Rhino, were you 'fasting' at the time of the labs? Glucose seems a bit high for fasting purposes ...
Again, sticking more on the thyroid side ... Both Free T4 and Free T3 are hovering in the low 40% percentile of their respective reference ranges. I don't see a current Reverse T3, so I can't comment on it or its ratio comparison with FT3. However, "if" everything is/was working just right, you would probably want to see that Free T3 sitting in the 50% to 80% side of the reference range, say like 3.2 to 3.8pg/nl give or take ...
Now, I wish it was that simple, then it would be as easy as just titrating your NDT grain dosage. Unfortunately, it's not that simple. Your iron and ferritin levels as you can see are super low. Much too low for T3 to work effectively at the cells. So, if you titrate your NDT, FT3 is going to increase, but so will RT3. With your iron & ferritin at those levels, FT3 will pool. The body will pick up on this and turn up the demand for T4 to convert higher levels of RT3.
That is a great natural regulation switch, which picks up when we are sick, overly stressed and fatigued, etc., conserving resources and energy as the body repairs. Pooling becomes a bit more problematic in this case, because you're administering exogenous thyroid meds, which have both T4 and T3 (plus T2 and T1 if you get technical lol). Unfortunately, thyroid medication can be counterproductive in certain instances, and this is one of those instances. This is just my .02 my friend, I'm not a doctor, and others will have opinions. Just do your research and get familiar with how the pathways really function, and what their purposes are (?).
If you're doing a lot of donating of blood, I'd suggest stopping for a bit, but you really need to have a physician give you some direction on this(?). Some serious elemental iron would be in order, but you also need to factor in adequate supplementation of Vitamin C and other items to make this work ... First, try to determine why these levels are so low. If it's just continuous donations, easy peasy. If it's some other metabolic condition, work close with a good physician to find the root and get your program on track.
