The Gold Standard Diagnostics Borrelia burgdorferi VISE-OspC IgG/IgM ELISA Test Kit is intended as a qualitative test for the detection of IgG and IgM class antibodies to VISE and OspC antigens from Borrelia burgdorferi sensu stricto in human serum from symptomatic patients or people suspected of having Lyme disease. When used as the first-tier screening test, positive and equivocal results must be confirmed through additional testing by one of the following methods:
» Standard two-tier test methodology (STTT) using an IgG and/or IgM blot testing following current interpretation guidelines, OR
» Modified two-tier test methodology (MTTT) using one or more of the following three ELISA based assays:
a. Gold Standard Diagnostics Borrelia burgdorferi [gG/IgM ELISA Test
b. Gold Standard Diagnostics Borrelia burgdorferi IgG ELISA Test
c. Gold Standard Diagnostics Borrelia burgdorferi IgM ELISA Test
The assay can also be used as a second-tier confirmation test using the MTTT methodology when used with one or more of the following three ELISA based assays:
a. Gold Standard Diagnostics Borrelia burgdorferi [gG/IgM ELISA Test
b. Gold Standard Diagnostics Borrelia burgdorferi IgG ELISA Test
c. Gold Standard Diagnostics Borrelia burgdorferi IgM ELISA Test
Positive test results by either the STTT or MTTT methodology are supportive evidence for the presence of antibodies and exposure to Borrelia burgdorferi, the cause of Lyme disease. A diagnosis of Lyme disease should be made based on the presence of Borrelia burgdorferi antibodies, history, symptoms, and other laboratory findings.
