For those who test positive in low prevalence settings, the high false positive rate means that mitigation strategies, such as molecular testing to confirm positive results, are needed. Ag-RDTs, when used appropriately, are promising tools for scaling up testing and ensuring that patient management...
Assembly and publication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome in January 2020 enabled the immediate development of tests to detect the new virus. This began the largest global testing programme in history, in which h
n = 16) or who continuously experienced symptoms at month 4 (T1) and month 8 (T2) postinitial SARS-CoV-2 infection (LC,n = 27). The WHO definition for LC is persistent symptoms for 3 months or more after infection14. All analyzed PBMCs, sera and plasma were from 8 m...
A low event rate for death, ICU care, or ventilator therapy precluded assessment of hypogonadism as a risk factor for severe COVID-19. Also, because most hospitalizations were during the first year of the pandemic, when COVID-19 vaccines were not available (eFigure 2 in the Supplement), ...
Molecular (PCR) tests are much more sensitive than antigen tests. For instance, if you have COVID but don't have any symptoms, an antigen test might give you a negative result. This is called a "false negative." Molecular tests are more accurate, but they take longer. You may wait a...
Your nose is swabbed and the sample tested on the spot using a chemical. You get results in as little as 10 minutes. Generally, theantigen testis not as accurate as the PCR test. If you get a positive result, it means you likely have COVID-19. But a negative result could be false....
The homemoleculartests delivered by that program – Pfizer's Lucira test for COVID-19 and flu – are more sensitive than other kinds of at-home rapid antigen tests that had been shipped from the USPS orders. That program is set to wind down in mid-April, a spokesperson for the NIH's ...

quarantines could be proven safer and more cost-effective than 10/14-day quarantines. However, the effectiveness of a test-assisted quarantine strongly depends on test sensitivity requiring a rate higher than 85% to detect infectivity13. The 5 best RATs in our study are suitable for this ...
