We have developed ultrasensitive single molecule assays for multiple relevant SAR-CoV-2 proteins that can detect both active virus and prior infection. The assays have been tested in thousands of individuals, including patients and healthcare workers and exhibit exceptional sensitivity and specificity. Additionally, we have followed these protein concentrations over time during the course of disease in many patients and can predict outcomes based on the dynamics of the protein responses.
