Werfen today announced that its Aptiva Antiphospholipid Syndrome (APS) Immunoglobulin A (IgA) Reagent has received both U.S. Food and Drug Administration (FDA) 510(k) clearance and CE Mark under the European Union’s In Vitro Diagnostic Medical Devices Regulation (IVDR). Together, these milestones complete the Aptiva APS testing portfolio, which now offers all three APS isotypes, IgA, IgG, and IgM, for both anti-cardiolipin (aCL) and anti-beta 2 glycoprotein 1 (aβ₂GP1) antibodies. 

The achievement expands global access to comprehensive APS testing on Aptiva and further strengthens its growing portfolio of assays, which also includes testing for Celiac Disease and Connective Tissue Diseases (CTD). Together, these assays provide laboratories with a more comprehensive solution for autoimmune testing and patient evaluation.

The Aptiva APS IgA Reagent utilizes Aptiva's particle-based multi-analyte technology (PMAT) for the semi-quantitative determination of anti-cardiolipin (aCL) and anti-beta 2 glycoprotein 1 (aβ₂GP1) IgA antibodies in human serum. When used alongside the Aptiva APS IgG and IgM Reagents, and in conjunction with other laboratory and clinical findings, the IgA assay provides additional diagnostic information that may aid in the diagnosis of both primary and secondary APS.  

Antiphospholipid syndrome is an autoimmune disease characterized by thrombotic events and pregnancy-related complications and can be difficult to diagnose because its clinical manifestations often overlap with other conditions. Having access to a complete APS antibody profile may provide clinicians with valuable diagnostic insight and support patient management decisions.  

"Completing the APS isotype panel with the addition of IgA significantly enhances the clinical value of the Aptiva system," said Anthony Prestigiacomo, Vice President of Research and Development at Werfen. "APS can present with nonspecific or overlapping symptoms, making diagnosis challenging. By offering all three isotypes, clinicians and laboratories can obtain a more comprehensive assessment that supports informed clinical decision-making and improved patient care."

The Aptiva APS portfolio now includes FDA-cleared and CE-marked APS IgA, IgG, and IgM reagents, enabling laboratories in the United States and Europe to access a complete APS testing solution on a single platform. These assays complement Werfen's Aptiva Celiac Disease and CTD offerings and continue to expand the menu of autoimmune disease markers available through Aptiva.

Aptiva is a fully automated, next-generation multi-analyte system designed to streamline autoimmune testing workflows. Powered by PMAT, the system processes multiple analytes simultaneously from a single patient sample, delivering high throughput with minimal hands-on time. Aptiva helps laboratories improve efficiency while providing comprehensive diagnostic information to clinicians.

"As the Aptiva menu continues to expand, with additional key biomarkers in development, we are building a platform that advances laboratory efficiency while delivering deeper clinical insight," said Vijay Namasivayam, PhD, Chief Operating Officer at Werfen. "The FDA clearance and CE Mark for APS IgA represent important milestones in our commitment to expanding access to innovative autoimmune diagnostics worldwide."

With the addition of APS IgA, the Aptiva portfolio now comprises a comprehensive menu of autoimmune markers across key disease states. This continued expansion underscores Werfen's commitment to delivering innovative, consolidated solutions that help laboratories achieve high-quality diagnostic results and support better patient outcomes.
