Comparison of serological EIA tests available in Poland, used in diagnostics of
Lyme borreliosis: VIDAS
Lyme Screen II (LYT II)-bioMérieux (France),
Lyme Borreliosis-Dako (Denmark), Borrelia Recombinant-Biomedica (Austria) was carried out in sera of 112 persons: 39 inhabitants of Bia?owieza area-
Lyme borreliosis endemic region, 43 persons with
Lyme borreliosis (first of all erythema migrans and neuroborreliosis), 27 healthy persons (control group), 3 persons with serologically confirmed rheumatoid arthritis. Compatibility of results in all tests was 73%, and it was the highest in control group (78%) and in neuroborreliosis patients (76%). Sensitivity of all tests was similar and varied from 77% (Dako) up to 81% (Biomedica). The highest specificity (93%), positive (94%) and negative (74%) predictive values demonstrated bioMérieux test. The lowest error of method for positive results showed bioMérieux (2,48%) and Dako-IgG (2,94%), whereas for negative Biomedica-IgG (0). There were no positive (false) results in sera of patients with rheumatoid factor dependent on cross reaction.
