Clin Chem Lab Med. 2026 Apr 20. doi: 10.1515/cclm-2025-1709. Online ahead of print. ABSTRACT OBJECTIVES: To evaluate whether antinuclear antibody (ANA) titre or HEp-2 fluorescence patterns are associated with antiphospholipid antibody (aPL) serological intensity, and to examine component-specific complement abnormalities – particularly low C4 – as laboratory correlates compatible with classical-pathway involvement. METHODS: This retrospective … Read more
