Reliable testing for Lyme
Lyme specialty labs frequently produce false-positive results and fail clients
One half of a paper/commentary pairing that appeared a couple of days ago in the Canadian Medical Association Journal - http://www.cmaj.ca/content/early/2015/08/31/cmaj.150874
A related paper here: http://www.cmaj.ca/content/early/2015/08/31/cmaj.141413
Unfortunately, both require payment, even the commentary. Which means most Canadians will only see this sort of report:
“After getting a negative test in Canada, some people still think their symptoms are caused by Lyme, and they read on the Internet that these specialty labs are better,” said Gregson. “But they’re not better at picking up Lyme, and are actually producing more false-positive results.”
He said the standard Lyme symptoms — joint pain, rash, headaches — are pretty general, which can be frustrating for patients seeking answers.
“People are just looking for a cause of their symptoms. They want something that’s treatable. They’re looking for relief, so they think ‘well, maybe Lyme is the cause, I’ll go get my tests done as recommended by all these other people on the Internet.’”
Gregson said a specific testing method is causing all the false-positive diagnoses.
“There’s a testing method called the western blot, which looks at multiple antibodies on a single testing strip. We have specific criteria for positive results.”
