European Lyme Disease (Borrelia afzelii and Borrelia garinii)Įuropean Lyme testing must be specifically requested on the PHO General Test Requisition and you must indicate all relevant clinical information and travel history of the patient. Thus during the later stages of disease (i.e., early disseminated Lyme disease, and late disseminated Lyme disease), serological testing becomes useful in confirming a B. As infection progresses and the immune system responds to the infection, patients develop sufficient antibodies. These patients are diagnosed clinically and should be managed appropriately regardless of serological results. In patients with early localized disease, serological testing is not recommended because at this stage the ability of serology to detect infection is poor as the immune response has not fully matured. The laboratory testing results are used to confirm clinical suspicion of Lyme disease. The diagnosis of Lyme disease is made based on a person’s exposure to blacklegged ticks, with compatible signs and symptoms of Lyme disease. If the ELISA is reactive or indeterminate, PHO will perform Western Blot to detect Borellia burgdorferi IgM and IgG antibodies. This will consist of a Borrelia VlsE1/pepC10 Borrelia (Lyme) IgM/IgG ELISA. PHO will continue to use a two-tier test method as recommended by the Canadian Public Health Laboratory Network1. burgdorferi antibodies and results will be reported the same way (Reactive, Non-reactive, Indeterminate). Based on evaluation and comparison of assays, the performance characteristics of the new assay will not have an impact on detecting B. The assay change is a result of a competitive procurement and technical evaluation at PHO on Health Canada approved Lyme Disease IgM/IgG ELISA.Public Health Ontario (PHO) is changing the C6 peptide Borrelia burgdorferi (Lyme) IgM/IgG ELISA to a VlsE1/pepC10 Borrelia (Lyme) IgM/IgG ELISA. ![]() Lyme Disease Serology Update – Implementation of VlsE1/pepC10 IgM/IgG Borrelia assayĪudience: Health Care Providers, public health unit personnel, specimen collection centres Overview: Public Health Ontario (PHO) Labstract – November 2017 All clinically diagnosed and confirmed cases are reportable to the health unit. The Labstract update is also available from Notification: Lyme Disease is a mandatory reportable disease, according to the Health Protection and Promotion Act, R.S.O., 1990. We would like to take this opportunity to share the update from Public Health Ontario to clinicians and laboratories. There has been a recent change in serology testing for Lyme Disease, effective as of November 27, 2017, in Ontario.
