From: Rapid serological detection of autoantibodies associated with Sjögren's syndrome
QLIPS detection of anti-Ro60 and anti-Ro52 autoantibodies in SjS. QLIPS detection of autoantibodies against Ro60-Δ2 and a C-terminal fragment of Ro52 (Ro52-Δ2) in 25 normal volunteers and 57 primary SjS patients. (A) The anti-Ro60-Δ2 antibody test. (B) The anti-Ro52-Δ2 antibody test. Each circle or square symbol represents individual normal controls or SjS patient samples, respectively. The solid lines represent the GMT for each group. For determining sensitivity and specificity, the dashed line represents the cut-off level derived from the control mean plus 5 SD.
