The silly thing is that I actually have the AcHR antibodies but it is around half of the reference range (0.12) and considered negative which puzzles me as it seems such a contradiction - they say titre levels do not corrorolate to severity of disease.....and yet there is an acceptable level allowed in the bloodstream?? So, I have a consistent level of antibodies (for over 10years now) and all the symptoms associated, and yet, I am considered negative! Hopefully thoughts will change on these guidelines - as I said, it seems slightly contradictory, but I am no doctor!!
As you said - it is a strange disease!!
