I don't know about the ELISA test- I've sort of given up on having my doctor or family believe me at this point.
I too have been passing Very large flukes that look like mushrooms since begging this herbal parasite cleanse (as well as a host of other things I'm quite shocked to learn were inside of me!)
I've only been juicing and not eating mushrooms or any solid food (yesterday, with the herbal formula, I also ate about 3 tblsp of papaya seeds and that combined w/the herbs is what pushed so many out- I was passing them for a good 10 hours last night).
I'm so freaked out by this I don't even know what to do except to continue on...
