I think they are testing with PCR on the phages. Because there are 1000 phages for one bacteria, the chance of getting a positive PCR is a lot bigger, than when you would do PCR on borrelia itself. Also because the borellia bacteria is in the tissue and not in the blood. The phages are apparently in the blood.
They are actually able to test on the different kinds of Borellia, have already heard from different people that they had different subspecies (borellia hermsi or myamotoi).
PCR tests can be false negative is the sample doesn’t have the DNA if the virus or bacteria in it. In this case, it’s apparently pretty sensitive, so not many false negatives. I know that they have tested on a lot of other species, to see if there was cross-reaction, but I don’t know exactly how specific the test is. Every test has false negatives and false positives.
I always tested negative on every lyme test, even though it seemed very likely that I would have lyme.
This test tested me positive on borellia myamotoi. I was very sceptical, but decided to do the lyme treatment, so I would never have any regrets later.
I have just finished the last treatment (did the 6 weeks of antibiotics, followed by 3 months of disulfiram). It took me 11 months in total, but I have no regrets. I am so much better at the moment, I don’t know yet for sure if it’s going to last of course, but I would definitely do it again.
