Wow that is quite a collection. What ever you are doing is working. Dr. Amin's lab in Arizona takes full specimins but I had no better luck with him than the local lab. When you had your surgery did you have to have blood given to you. I found out they do not screen blood products for parasites and I think that is a source for many people and explains why they get sick with these things after a major sickness or surgery. Flukes can also come from fruits and veggies. You have to soak them for 15 minutes or more in bleach or peroxide water. Many fruits and veggies are from other countries where they use human and animal waste as fertilizer. All it takes is one snail to leave a cyst on the plant.
