From: Rapid serological detection of autoantibodies associated with Sjögren's syndrome
Ro52-Δ2 QLIPS testing with an independent validation cohort. Antibodies were evaluated by QLIPS with 107 SjS and 30 control sera. Each circle or square symbol represents individual normal controls or SjS patient samples, respectively. The solid lines represent the GMT for each group. The cutoff of 37,806 LU, previously determined from the initial cohort in Figure 2B, is shown by the dotted line and results in 66% sensitivity and 100% specificity.
