• Connective tissue diseases (CTD) are a group of disorders characterized by inflammation and autoimmune reactions that affect multiple organ systems
  • The diagnosis of CTD uses IFA (Immunofluorescence Assays) for the determination of antinulcear antibodies (ANA), using human epithelial tumor cells (HEp-2), a stabilized cell line of human larynx carcinoma, known for its high sensitivity and specificity
  • Having reliable solutions and high-quality HEp-2 cells are essential to proceed with clear identifications of ANA, making the diagnosis of CTD tempestive
