There is no reference range next to this reading, but it says 'No Action'. However, there is also a whole paragraph about Anti TPO antibodies being present in most patients with Hashimotos Thyroiditis and Graves etc. This paragraph ends "it follows that this is a non-specific investigation". I am really not sure what this antibody reading means, although the few web pages I have brought up seem to suggest it is quite high antibodies. Any advice would be very welcome and thanks to all those who have responded to my previous posts! Roz
