Antibody testing is the process of analyzing a patient’s blood to determine if present antibodies are fighting off an illness regardless of their symptoms. As the CDC explains, an antibody or “serology test" can detect infections in patients that have no symptoms. Asymptomatic patients can be carriers of COVID-19, which means that an antibody test is the most accurate way to determine if they have COVID-19.
Many public health organizations are using antibody tests to determine the full scope of COVID-19 infections among both symptomatic and asymptomatic patients. National research efforts rely on antibody tests to find new ways to protect the public against the virus. At the individual level, patients can visit an urgent care center, just like AFC Urgent Care Methuen, to get test results in a day after the visit.
