The SARS-CoV-2 pandemic has brought to light multiple considerations when approaching infectious diseases on the global level. These range from diagnostic platforms, to therapeutics, and prevention agents. In this article, we focus on the engineering platforms and considerations when applying serologic assays to multiple geographic locations, climates with varying endemic virus repertoires, and different laboratory and clinical resource settings. Serologic assays detect antibodies that react against viral proteins, suggesting prior infection and correlative of an increased likelihood of immunity to future infection. As these assays are focused on the human immune response to a pathogen, and humans are variable, there are a number of important engineering steps to optimize assay performance, from sample collection, to assay execution and data analysis. Moving forward, a global approach to infectious disease detection and prevention is necessary to prevent the spread of future viruses with pandemic potential.
