I saw his blood test cause I requested a fax of it. It looks like it tests for basic things really like vitamin levels, liver levels and a few other things if I remember correctly.
From curezone I've seen posts saying that Jetti Katz is a big rip off so personally I don't feel like even going there. I think the doctor there has se shady online reviews too. Also from their site it looks like their tests are pretty expensive too. Just a routine parasite stool test is 400 dollars from their site and some other ones are over 600.
A test I ordered from a lab called meridian valley labs is around 70 dollars - a lot cheaper and it seems like a broad spectrum test, haven't tried it yet but it wasn't that much money at least. Biohealth also has a test, I'm not sure how much it is but they seem like a fancy lab and the test is very broad spectrum. I haven't tried these yet so can't attest to their reliability but I guess I feel shady about spending hundreds at jetti katz when other places seem like they may have more potential for the money spent.
I think Cahill may have meant places that get loads of money like cancer centers to dedicate their time to treating them. I haven't really found a tropical place that takes insurance besides Jacobi Parisitology but they didn't find anything ether - they may prove benefical to someone that has parasites that could show up on a seriology test easily but I guess there are many different types of parasites that aren't so easy to find apparently.
