(I have no idea why my reply turned out bold)
Yes she has Hashimoto hypothyroid at the time of this test. But- just barely, and why a Dr would not suggest thyroid hormone supplement yet.
A smart Dr would suggest a re-test in less than three months.
The turning point to Hashimoto is gradual. Like water temperature going from cold to hot, there is all that area between the two.
T4, FREE 1.0 0.9-1.4 ng/dL (the very end of the low limit is .9; she is at 1)
She is on the edge of being hypo with the low but in normal range of Free T4 hormone at 1.
Probably is more hypo some days, less hypo other days, it changes a little day to day.
Technically, she has a slight case of Hashimoto right now - high antibody levels are what separate hashimoto hypothyroid from regular hypothyroid.
This right here is Hashimoto: THYROGLOBULIN ANTIBODIES 6 H < or = 1 IU/mL;
Thats why it has an "H" for high.
Its not very high, but its over the limit of the range performed on the specific test instrumentation/machine used at that lab. Different brands of test machines have different ranges for antibodies.
If her levels gets worse, more hypo, the pattern you will most likely see Is: The antibody will go higher making the free T4 fuel hormone go lower, which turns up the tsh signal higher as well.
**Since its not that bad, it might just clear up on its own as lyme gets better. But makes sense to monitor by retesting the antibody and free T4 occasionally.**
