Negative: Ratio less than 0.7 Grey zone: Ratio 0.7 - 1.0 Positive: Ratio greater than 1.0        ENA screening assay includes the collective qualitative determination of antibodies directed against human recombinant proteins: U1RNP (RNP70, A, C), SS-A/Ro (60kDa/52kDa), SS-B/La, Centromere B, SCl-70, Jo-1 and syntetic peptide SmD3.       For more specific determination, they can be requested separately.             Version of Test: 7

Negative: Ratio less than 0.7 Grey zone: Ratio 0.7 - 1.0 Positive: Ratio greater than 1.0      The ENA screening assay includes the joint determination of antibodies directed against human recombinant proteins: U1RNP (RNP70, A, C), SS-A/Ro (60kDa/52kDa), SS-B/La, Centromere B, SCl- 70, Jo-1 and synthetic peptide SmD3. Consequently, a negative result in this pooled ENA study implies that none of the antibodies directed against the aforementioned individual proteins are detectable.                                        Version of Test: 8
