Oh, I'm sorry that your tests came back as negative, Springsjean - especially if you have enough of the symptoms to still warrant treatment.
Yes, the tests for the co-infections are just as unreliable as the ones for Lyme. Bartonella has at least 27 different strains that have been discovered now, Babesia has over 20.
I would suggest that you look into Dr. James Schaller's writings (
