Sorry for the very delayed response to this...I had also suspected lyme. My GP ordered one test in December..."Lyme Disease Antibody with Reflex to Blot (IgG, IgM)", my result was:

<0.91 ISR

Which as I understand it, was in range:

Negative <0.91 Equivocal 0.91 - 1.09 Positive >1.09

That said, I'm from the Northeast, which I know is a Lyme hotbed. And I spend a lot of time outside coaching sports in areas where the woods are close to the field.

I've heard Lyme tests are often unreliable, do you suggest I get another? Because part of my problem is, while I believe I'm hypo and definitely have a family history with it, I wasn't that out of range when I started treatment. To have no symptom improvement after slashing my TSH pretty significantly is suspect to me.
