Some people using antigen tests have experienced a negative test result only to find out that they have the virus. New research shows that repeat testing every other day increases the detection of the SARS-CoV-2 virus.

The use of rapid Covid tests has soared this year with the spread of omicron and free shipments organized by the Biden Administration. But in August the US Food and Drug Administration cautioned that people who get a negative result should still repeat the test a couple days later. That communication has led to a lot of confusion.

A research team funded by the National Institutes of Health has shown that commercially available rapid antigen tests can detect past and present variants of concern and has identified potential mutations that may impact test performance in the future.

NIH has issued two new funding opportunities for diagnostic test manufacturers to develop the next generation of COVID-19 diagnostics.

A new study that could have immediate implications for COVID-19 testing in schools found that with age-appropriate instructions, school-aged children can successfully use a nasal swab to obtain their own COVID-19 test specimen.

Researchers funded by NIH's RADx Tech program have developed a fast, cost-effective method to detect the circulation of SARS-CoV-2 variants. The team adopted a customizable genotyping approach to identify known variants and subvariants—an approach that can augment current surveillance.

A new type of COVID-19 test is hitting the market, and could change how we detect the virus. MicroGEM, a Virginia-based molecular biology company with a Charlottesville office, is using its new saliva test to track COVID-19. Source: NBC TV12 Richmond, Virginia.

Two recent studies supported by the National Institutes of Health Rapid Acceleration of Diagnostics (RADx) Tech program demonstrate how widespread distribution of COVID-19 at-home antigen tests can be used as an effective public health strategy to reduce the spread of the disease.

RADx Tech program has issued contracts to help meet the ongoing needs and challenges of COVID-19 diagnostic testing.

The National Institutes of Health’s Rapid Acceleration of Diagnostics (RADx®) Tech program is working to identify necessary elements of at-home COVID-19 diagnostic test kits that may be used independently by people with disabilities.
