Developing a Salivary Antibody Test

EPA researchers have developed a simple, easy-to-collect, low cost, non-invasive antibody test using saliva samples. Antibody testing helps identify people who have been exposed to SARS-CoV-2 and have subsequently developed an immune response, even if they may not have developed symptoms. The EPA team has tested more than 200 samples from recently infected individuals across the United States and is in the final stages of validating this test. The antibody test could help public health officials determine the rate of infection and provide insights on the true impact of the pandemic in communities across the country.
