Thanks... yes I hav

A previous lurker... but this interested me enough to look further. The above posted information is from a "letter to the editor" in Journal of Infection. It is not a study, and is based on the observation of one patient's case. Near as I can tell, the doctors are basing the assumption (that IVIG caused false positive) from the fact that the pre-IVIG blood sample turned up false for borrelia, while the post IVIG sample was positive. As is well known, false negatives are highly possible with borrelia -- so there is no way to say that wasn't the case with the original pre-ivig blood draw. And perhaps the IVIG procedure provoked a positive test. There is simply no way to know. I'm not saying that IVIG will never cause false postive. I honestly do not know if there is any authoritative medical research out there that has stated this. But this letter of one case observation should not be relied upon as evidence of such.
