The Myth
I was tested for Lyme disease at the provincial lab and the results were negative. I guess that means I can’t have Lyme.

The TruthActually, that’s untrue. Evidence suggests that Canada’s Lyme testing methods are flawed.

False negative test results are common, especially in the early stages of Lyme. It takes time for antibodies to develop, so early tests often miss the bacteria. Contrary to bureaucratic statements, late stage Lyme disease antibody testing is much less accurate.
