Objectives Anti-parietal cell antibodies (APCA) are a serologic marker of autoimmune gastritis. Their prevalence in healthy individuals is not well defined. Methods We evaluated APCA prevalence in 515 healthy blood-donors by rat/primate tissue indirect immunofluorescence (IIF), enzyme-linked immunosorbent assay (ELISA), and immunoblot. Results...

A dense fine speckled pattern (DFS) caused by antibodies to the DFS70 kDa nuclear protein is a relatively common finding while testing for anti-nuclear antibodies (ANA) by indirect immunofluorescence (IIF) on HEp-2 cells. However, despite many efforts and numerous studies, the clinical significance of anti-DFS70 antibodies is still unknown as...

Reflex tests are widely used in clinical laboratories, for example, to diagnose thyroid disorders or in the follow-up of prostate cancer. Reflex tests for antinuclear antibodies (ANA) have recently gained attention as a way to improve appropriateness in the immunological diagnosis of autoimmune rheumatic diseases and avoid waste of resources....
