![]() This could lead to false-negative results, even in a case where an individual was actually positive for COVID-19. If there is not very much virus in the sample, the brightness of the color-its signal-is quite faint, or even undetectable. However, lab-based PCR tests require expensive equipment and several hours to run.Īt-home rapid tests, on the other hand, have the advantage of requiring no instrumentation, but generate an unamplified signal by using specially designed antibodies to stick colored reporter molecules onto any SARS-CoV-2 proteins present in the sample. Even a tiny amount of SARS-CoV-2 in a sample can be detected by a PCR test, making it the gold standard for detecting infection. With laboratory-based polymerase chain reaction (PCR) testing, any fragments of the viral RNA genome that are present in a patient's sample are used to generate multiple DNA copies, yielding an amplified signal that can be detected more easily. Unfortunately, we know that we are going to face more pandemics in the future, and we need to be ready to respond."Ī major challenge in instrument-free at-home testing for COVID-19 is that SARS-CoV-2 (the virus that causes the disease) can be present in a given sample in very low amounts. "But with the COVID-19 pandemic, we quickly learned that scaling diagnostics rapidly to the level of the human population is a huge challenge. ![]() "Many have thought of diagnostics as a ‘solved problem,'" says Pierce. The research was conducted in the laboratory of Niles Pierce, professor of applied and computational mathematics and bioengineering and executive officer for biology and biological engineering, and is described in a paper in the journal ACS Infectious Diseases. While the test was developed for COVID-19, the technology can be used as a platform for designing tests to detect other pathogens as well. Currently the state requirement for reporting is a positive PCR test or a positive antigen test administered by a trained individual at a testing site.Technology Transfer & Corporate PartnershipsĬaltech researchers have developed a new at-home test for COVID-19 that is more than twice as sensitive as current state-of-the-art antigen tests. In keeping with the State of Wisconsin’s COVID-19 reporting practices, you are not required to submit results from self-administered antigen tests to the MyUHS app or website. You may take the test immediately or keep it to use later. You will administer the test yourself, following the instructions in the test kit.
