It was recently pulled without explanation. In this webinar it was claimed that 2-tiered testing was 97-100 % accurate in Late Stage Neurological Lyme Disease, but no pathology was offered as proof. Throughout the webinar there were many examples of poor scientific method, assumptions, and unsupported statements. Ultimately the conclusion was new and better Lyme testing had to be created, but if the 2-tiered approach is 97-100% accurate why would they need a better test?
Contrary data Testing:
NY Dept Health 1996: found CDC 2-tiered testing missed 82% positive Lyme cases. Dept of Health report to CDC April 15, 1996
Johns Hopkins study 2005: found CDC 2-tiered testing missed 75% of positive Lyme cases IDSA Lyme Disease Guidelines
Commercially available FDA-approved kits are only 36-70% sensitive, : the ELISA assay does not have adequate sensitivity to be part of a two tiered approach to diagnosis.
Johan S. Bakken Journal of Clinical Microbiology, 1997 [35(3): 537-543] IDSA Lyme Disease Guidelines
Six more studies showed 2-tiered testing inadequate and missed on average 56 % of Active Lyme cases.
I might point out that all of this data only pertains to Borrelia burgdorferi, and all the tests use B-31 laboratory strain of Borrelia burgdorferi, but now we have 10 more human pathogenic Lyme strains that the tests cannot address with the same sensitivity as B. burgdorferi.
So how much more false positives would we have seen if the test sera that they used to test the current 2-tiered tests sensitivity was from patients with Borrelia bissetti or Borrelia valasianna or B. americana ????

The original CDC link about Lyme disease testing continues to display a message in large-size type which clearly informs and instructs readers that the "Page Has Moved". It clearly advises the reader to "update your links and bookmarks to the Lyme Disease home page."
The new CDC link about Lyme disease testing is http://www.cdc.gov/lyme/diagnosistesting/index.htmlThis Page Has Moved.
The page you requested has been removed.
Please update your links and bookmarks to the Lyme Disease home page.
It is ridiculous to allege that the video was "pulled without explanation". The video is still there. There is still an updated link displayed on the original webpage re-directing readers to the new CDC Lyme disease page where the video is now located. The CDC sent out a message to all subscribers instructing them that the CDC website about Lyme disease was updated as well. Anyone can subscribe for free. Readers should take advantage of the free subscription rather than depend on misinformation being spread by parties with alternative interests.Tom Grier wrote:It was recently pulled without explanation.
