Doctor says no thyroid problem-but could I

[milda]

I have had many symptom over the past 10 years that indicate a thyroid problem.  My mother was hypo, my sister was hypo, my niece was hypo, and my daughter has graves.  I have had different tests over the years and have not been diagnosed with it.

I had my Ferritin (serum) tested this past summer.  It was 17 (range of 10-291), so it was low.  A friend told me there is a connection between a low ferritin blood level and thyroid.  My most recent test was as follows:  T4 0.93; TSH 2.77; and Total T3 105.  

Does anyone have a opinion on these blood levels.  I just don;t feel well and wonder if my doctor is overlooking my tests, or if there are other thyroid test to be taken.

Thanks.

it is supposed to be more accurate than tsh t3 and t4 blood tests

[sleepyinkc1]

there is a 24 hour urine test that is suposed to be the most accurate it measures t3 and t4

Is the T4 a total T4 or Free T4?  Total T3 is pretty much useless and is rarely even tested any more because a lot your T3 could be bound to protein, which would make it unavailable to the body for use.  Same goes for T4.

You need to be tested for both Free T4 and Free T3 in order to find out how much of each is actually available for the body to use, with FT3 being the most important.  

You also have not posted reference ranges for the T4 or Total T3, so members can not tell where you fall within the lab's ranges.  Labs use different ranges depending on the method used for testing.  

All that said -- your TSH is in the high normal range and depending on your FT3 and FT4, along with symptoms, you could have hypothyroidism.  

You should ask for testing for FT3, FT4, TSH, TPOab (thyroid peroxidase antibodies), TGab (thyroglobulin antibodies) and I think the best test to check for Graves is the TSI test, which I'm not familiar with since I'm hypo/Hashi......

I'm not sure of the connection between ferritin levels and thyroid function.  I know that ferritin levels indicate how much iron the body is storing -- MY ferritin levels happen to be high and I am hypo/Hashi...........

You might also ask to get tested for vitamin b12 levels.........some symptoms of pernicious anemia can mimic thyroid issues.......I was first diagnosed with pernicious anemia and when b12 shots didn't solve all the problems, was later diagnosed with hypo and still later with Hashimoto's.............

If your T4 is a Free T4, then it is a little low.....should be mid normal range. Total T3 is an outdated test and shouldn't be used. The Free T3 is the most active thyroid hormone in the body.....that is the proper test to run with the Free T4 and TSH.
Yes you need to get your Ferritin level up quite a bit!
