I did in 2013 - already was being treated for hook and sound?- did testing half way thru treatment . I sent saliva? samples and stool samples etc. Saliva showed I had produced antibodies for hook tape round trichenella and toxoplasma- wow this meant I had at some point been exposed to these not necessarily meant I had them currently - tape was a surprise but made sense and I had seen rice like things in stool about a year before I began treatment - didnt eat rice at all nor anything that had resembled rice - weight loss hunger issues so treated for that as well. It did rec further testing to see if currently infected which we didnt bother doing just kept treating. good luck - if nothing else it gives you direction - my lab results were not recognized by my gp or other docs in my area - they disregarded it - I was recieving treatment via naturopath. Trying to convince general doc was a lost cause for me at that time- I needed to get help so paid out of pocket for treatment not bothering with my gp at the time
