Nonsense. I had a cousin who found a worm on their dog and they took the worm in a jar to the vet and the vet identified it as a parasitic worm, so that's all you need to do.
You really need to stop throwing out all these claims about parasites, doctors, and labs without proof in case sick and desperate people read and start believing all the stuff you spout and go down that deadend road of thinking they have parasites and spending tons of money trying to get rid of something they most likely do not even have, or as you say, may not even be causing their problems.
Otherwise you're starting to sound like a slick gadget salesman who makes stuff up to scare people into buying their products.
