Re: Lyme Newsgroup Questions



Thank you for posting this interesting information.

Can I just add that the government of the UK is misusing CDC criteria,
as are all those in Europe who follow the guidelines of the EU-funded
body EUCALB on diagnosis, which are generally based on the CDC
approach, and require a positive blood test and CSF via the two-step
testing method as part of the mandatory criteria before a diagnosis of
neuro-Lyme can be given.
