Fortunately, Clongen Laboratories http://www.clongen.com, is working to expand its menu of testing for tick-borne infections. So far, it is the only lab I have heard of that tests for four species of borrelia, including burgdoferi, lonestari, afzelii and garinii, using PCR (polymerase chain reaction, which identifies bug DNA) testing, although I seem to recall one blogger, an ILADS-affiliated MD: http://www.lymemd.blogspot.com, writing that even more species of borrelia can be tested for at this lab. In his post on November 13th, he writes that this lab can also test for fifteen species of babesia! I did not find this information on Clongen's site but perhaps they have not listed all of the species that they test for there. In addition, they can apparently test for multiple species of bartonella, not just the commonly-known henslae. This is encouraging, because many species of the aforementioned infections exist, but labs have so far only concentrated on only one or two. What's more, current tests for babesia and bartonella are woefully inadequate, because these infections are extremely difficult to detect in the bloodstream.
Whether Clongen's DNA testing is more accurate than that of Fry labs or the others, however, I don't know. I would like to think that for the price of their testing, that their margin of error would be low, but this is tick-borne illness that we are talking about here, and no lab so far has been able to detect the B-B-B trio 100% of the time, due to errors in testing but also because infections aren't present in every random blood sample that gets squished under the microscope.
Still, if you've got the dough, doing DNA testing may provide a more complete picture of the infections you are dealing with. Earlier this year, when an Asyra device identified the energetic signatures of five different babesia species in my body, it brought to my mind the possibility that some of us might be dealing with unusual or multiple strains of infections, besides or beyond the usual borrelia burgdoferi, babesia microti and bartonella henslae.
Of course, I don't know how common or pernicious the "other" strains of these infections are, and how different the treatment protocol would be if a sufferer had borrelia afzelii instead of borrelia burgdorferi. Perhaps it depends somewhat on the type of treatment that is being undertaken; ie, homeopathy versus antibiotics. It seems that among the borrelia species, burgdorferi still rules as king in the United States, but since tests (up until now) have focused on identifying this species alone, it may be that it has simply been overrepresented. I don't know.
Finally, Clongen also tests for mycoplasma, anaplasma, ricksettia, and a couple of ehrlichia species, infections also common to the co-infected Lyme patient.
