A better indication of current vs. past infection is a series of tests done at IGeneX or other tick-borne disease specializing lab. If the tests show changing bands, the infection is active. If there are symptoms and positive bands (IgM or IgG or both) then that suggests a clinical diagnosis and treatment is warranted. But if I understand your title correctly, you have either a titer of 5 on the IgG and a titer of 6 on the IgM or these are the number of positive bands on a WesternBlot test - in either case, this would be a positive test and since you have symptoms as well, should be treated in my opinion.
