• What Can SARS-CoV-2 Serology Testing Tell Us About Immune Status?
  Two years into the global COVID-19 pandemic, the role of serology testing to evaluate immune responses has not yet been defined. This webinar will explore the role of serology testing to assess immune status. This includes understanding how SARS-CoV-2 serology testing results correlate with individual immune responses to COVID-19 infections or vaccinations, and the value of SARS-CoV-2 serology testing and potential role of quantitative assays in determining protection against COVID-19. This webinar will also review serological responses from SARS-CoV-2 variants with a new quantitative assay that can differentiate multiple neutralizing and binding antibodies within a single test.
• Making the Choice – Serology Assays in COVID-19 Diagnostics and Surveillance
  It has been suggested that combining serological diagnostic testing with molecular testing may be useful in confirming COVID-19 infection or exposure to the virus. This webinar will look at the role of serology tests in the pandemic response, the clinical value of a Total Ab assay, and the actual performance and clinical utility of Platelia SARS CoV-2 Total Ab Assay for the COVID-19 pandemic response. Presented by Jean-François Mouscadet.

• How Can Galactomannan Detection Improve CAPA Diagnosis?
  In this on-demand webinar, Pr Denning presents interesting data related to a retrospective multicenter review performed in France in 2020. For patients admitted to the ICU with positive SARS-CoV-2 qPCR, most included in this study were mechanically ventilated during their hospital stay. For patients whose clinical picture worsened, some may have had a blood and/or bronchoalveolar lavage sample taken for galactomannan detection, BDG, or PCR testing. In the case of a positive result, the patient was considered as having a probable underlying Invasive Pulmonary Aspergillosis (IPA). For patients classified within the “IPA” group, the mortality was significantly higher than patients classified within the “no IPA” group (71% mortality vs 37%).²
