Can someone please take a look at my labs (possible hyper)?

I'm dealing with some chronic health issues and have been getting lots of blood work lately.

One of my thyroid tests showed a mild hyperthyroid profile but docs don't seem concerned. My TSH is flagged low at 0.40 mIU/ml (range 0.47-5.01) and my Free T4 flagged slightly high at 1.88 (range 0.71-1.85) with a T7 flagged slightly high as well at 12.21 (range 5.0-12.0)

I seem to fluctuate in and out of the mild hyperthyroid states but even when my numbers are in range, they're only barely in range. I always seem to run a lower range TSH and higher range T4.

Doc thinks it's okay and might just be normal variant for me.

I'm dealing with some undiagnosed symptoms (mostly edema/swelling) and so am going over blood work with fine tooth comb in hopes of finding an answer or something overlooked

Are my numbers negligible or something to follow up? Like I said, they fluctuate and have been in these ranges for almost a decade. I'm a male, 45, BTW

Thanks for the detailed response and explanation, goolarra. I really appreciate it.

Yes, Quincy!. I wish I had someone like him or House on my case. I might have gotten some answers by now : ). Only on TV, I guess

Well, at least I can cross the hyperT stuff of the list. I just wanted to make sure that my docs aren't brushing something off that could be causing my symptoms (lots of gi issues and generalized edema). All the nasties like heart, liver and kidney failure have been ruled out and so my docs stuck looking for the rarer causes.

Quincy, huh?

AACE considers normal range for TSH 0.3-3.0.  Labs have been slow to adopt that "new" standard from about 10 years ago.

FT4 is a little on the high side, but we all have different personal ranges that we feel well in.  I agree with your doctor in that respect.  

FT3 should have been tested as well.  T7 (FTI) is considered obsolete and of little value.

My personal opinion is if your FT4 has been close to or slightly above reference range for 10 years and you don't have any clear hyper symptoms (do you?), your doctor has probably made a correct assessment.

Edema (where?) is typically a hypo symptom, not hyper.
