[QUOTE="Vettester Chris, post: 68804, member: 696"] Both your Free T3 and Free T4 are sitting at 54% of their reference ranges. You would normally aim to see both of these somewhere between 50% and 80%, so with that talking point you're in the zone, or call it towards the low end of the zone. With what's provided, nothing even close to "hyper", and for some might be borderline "hypo", depending on what free serum levels work best for you? The other factor with the Free T3 & T4 zone is Reverse T3 and its ratio. Ideally, a FT3/RT3 ratio that is > 20 will be ideal, and that's usually a good marker to know that FT3 isn't pooling, or call it not getting to the cells. When pooling you will "usually" see FT3 at a higher level in the reference range than FT4, sometimes substantially, e.g., FT3 at 75% and FT4 at 20% ... Again, both of yours are equal in the reference range, which is ideally a good thing. The only thing missing is a TgAb antibody lab. TPO only checks enzyme autoimmune, TgAb will check the protein side of it. You will want to know this going forward, especially if some form of treatment is ever in play. Also, your labs are one reason why it's not good to just rely on TSH lab alone. Some guys with the same FT3 and FT4 might be at 2.0 or 3.0uIU/ml on TSH, or higher or lower, it can be all over the place. Sometimes thyroid hormone levels can be fairly normal, but one might see their TSH elevated (a la sub-clinical of sorts) ... It's good to have, it's good to compare, but the real truth is with the other labs you posted (plus the TgAb when you can). Also, just for grins, talk with your physician about a 24 hour cortisol w/DHEA correlation kit. [/QUOTE]
