Summary
Proficiency testing for Lyme disease antibody assays showed high overall sensitivity (95.4%) and specificity (98.8%). However, variations in performance and cross-reactivity with other antibodies were observed across different assay types and test kits.
Area of Science:
- Medical Diagnostics
- Infectious Disease Serology
- Laboratory Science
Background:
- Accurate detection of Lyme disease (Borrelia burgdorferi) antibodies is crucial for diagnosis and patient management.
- Proficiency testing programs are essential for evaluating laboratory performance and ensuring reliable diagnostic results.
- Previous studies highlighted variability in Lyme disease antibody test performance.
Purpose of the Study:
- To evaluate the performance of various Lyme disease antibody testing methods through a series of proficiency tests.
- To assess the sensitivity and specificity of different immunoassay formats and specific test kits used in diagnosing Lyme disease.
- To identify potential sources of error, such as cross-reactivity, in Lyme disease antibody testing.
Main Methods:
- Nine proficiency test events were conducted between October 1988 and January 1992.
- Participants included 846 laboratories utilizing immunofluorescence assays (IFAs), solid-phase fluorescence immunoassays (SFIA), and enzyme immunoassays (EIAs).
- Performance metrics included overall and kit-specific sensitivity and specificity, as well as cross-reactivity analysis against Treponema pallidum and heterophile antibodies.
Main Results:
- Overall sensitivity averaged 95.4% and specificity was 98.8%.
- IFAs showed 98.7% sensitivity and 92.9% specificity; SFIAs had 97.4% sensitivity and >99% specificity; EIAs demonstrated 94.6% sensitivity and >99% specificity.
- Significant cross-reactivity was noted for specific IFA and EIA kits with Treponema pallidum and heterophile antibodies, ranging from 24% to 30%.
Conclusions:
- While overall performance for Lyme disease antibody testing is high, significant variability exists among different assay types and specific test kits.
- Certain EIA kits demonstrated excellent sensitivity, while others showed poor performance.
- High rates of cross-reactivity with Treponema pallidum and heterophile antibodies indicate a need for careful test selection and interpretation to avoid false-positive results.
