[QUOTE="Vettester Chris, post: 82839, member: 696"] Okay, at first glance we see Free T4 and Free T3, and where they sit in their respective reference ranges. FT4 is at 54.7% FT3 is at 41.6% If all things were semi-optimal, you would probably want to see both values in the 50% to 80% area of the reference range, and hopefully both FT4 and FT3 would be sitting relatively close to each other (e.g., FT4 at 67% and FT3 is at 64%). Being that FT3 is essentially what makes the greatest impact on energy, metabolism, ATP, etc., you will no doubt be seeing the "Hypo" type symptoms you described when it is low. On the Reverse T3, we are usually aiming to compare it against FT3 in a ratio analysis, taking FT3/RT3. Your ratio is 16.6. Ideally, most would probably want to see this >20. To talk about "pooling". Yes, the RT3/FT3 ratio is used as a marker for pooling of T3, meaning FT3 isn't adequately making it to the cells in the body, thus it's pooling or building up redundantly. T4 converts to T3-FT3, and./but it also converts to RT3 via 5'deiodinase. When all things are in balance, T4 will convert adequately to T3/FT3, and there will also be "x" amount of T4 converting to RT3. When things are NOT in balance (iron, ferritn, cortisol primarily), the body will shift a bit and T4 will convert more RT3. This also happens in cases where the body needs to conserve energy, i.e., illness, injury, internal stress, etc. Iron is pertinent with transporting T3 to the cells.
