Detection of IgG antiobodies in cerebrospinal fluid by ELISA<<Return to Laboratory
Detection of IgG antibodies to a mixture of whole antigen extracts of Borrelia burgdorferi sensu stricto, B. afzelii, B. garinii and recombinant VlsE of B. burgdorferi in cerebrospinal fluid (CSF) by enzyme-linked immunosorbent assay (ELISA).
- Lyme Disease
Fresh human serum and cerebrospinal fluid (CSF). A minimum volume of 0.25 mL of both serum and CSF is required.
Absolute values for total albumin and total IgG concentrations of both the serum and CSF must be provided, in order to perform interpretative calculations for this test.
Collect blood in serum separator tubes. Collect CSF into sterile tube without preservatives. The serum and CSF specimens should be collected from the patient within a one hour interval of each other, up to a maximum of 24 hours. If this timeframe is exceeded, the test results may be invalid.
Store samples refrigerated up to 5 days or store frozen until shipped for testing. Ship frozen on dry or with freezer packs.
Shipping of specimens shall be done by a TDG certified individual in accordance with TDG regulations. For additional information regarding classification of specimens for the purposes of shipping, consult either Part 2 Appendix 3 of the TDG Regulations or section 3.6.2 of the IATA Dangerous Goods Regulations as applicable.

Potential exposure to blacklegged ticks accompanied by clinical symptoms of neuroborreliosis.
Completed Requisition for Serological Testing for Selected Zoonotic Agents. If possible, include the clinical history and lab results performed at local or provincial laboratories.
Specimens may be subject to rejection if they are not the appropriate sample type, have insufficient volume, are not collected within a 24 hour time interval, or are not accompanied by relevant patient information and the indices stated above.
Commercial microplate ELISA kit. This is a quantitative test for the detection of IgG antibodies produced in the CNS to B. burgdorferi sensu stricto and pathogenic European genospecies of Borrelia.
Initiation of antibiotic treatment prior to testing may result in decreased antibody production which will affect the outcome of serological testing. However, if neuroborreliosis is suspected based on clinical symptoms, treatment should be initiated.
