Elevated antibodies, low TSH, high T3 and T4

[cjs17]

Hi there,
Any idea what these tests might indicate? I am based in NZ and my doctor is not positive on what it might be and I would like a second opinion.


Thyroglobulin Ab: 228 U/mL ( < 60 ) H
Thyroperoxidase Ab: 320 U/mL ( < 60 ) H

Free T4: 27.0 pmol/L ( 10.0 - 20.0 ) H
TSH: 0.02 mIU/L ( 0.30 - 4.00 ) L
Free T3: 8.4 pmol/L ( 3.0 - 6.5 ) H

Help would be much appreciated.

Many thanks!

Another thought occurred to me this morning.  When you go back for TSI testing, it would also be a good idea to get an ultrasound test on the thyroid glands.  That test will provide a look at the condition of the thyroid glands and also see if there are any nodules from the Hashimoto's.  Nodules can sometimes leak thyroid hormone into the blood faster than would normally occur.  This can cause short term swings from hypo to hyper.

Having a bit of insomnia tonight and noticed your post, so I'll take a shot.  Your TPO ab and TG ab tests show thyroid antibodies typical of Hashimoto's.  Assuming that you are not taking any thyroid medication, the high levels of FT4 and FT3 make me wonder about the possibility of also having Graves Disease.   Having both is unusual, but if you search the Forum archives, you will see patients who have posted that have had both.  Here is one example.

To confirm Graves disease you should have the Thyroid-Stimulating Immunoglobulins (TSI) test.
