Do you plan to travel very soon and the destination you are going to requires you to show proof that you are not infected with Covid-19? If that is so, you need to consider a rapid antigen test for travel. When the world was first stuck with this virus, testing for SARS-CoV-2 infection mostly relied on reverse transcription polymerase chain reaction (RT-PCR) performed on a nasopharyngeal specimen. This testing method remains the gold standard for detecting SARS-CoV-2 and is characterized by both high sensitivity as well as specificity in detecting viral ribonucleic acid (RNA).
However, the high volume of samples reaching the laboratories could lead to a shortage of reagents and disposables and to a further increase in the turn-around time for RT-PCR tests. For this reasons, people are turning to rapid antigen tests for Covid-19. Rapid antigen tests have become preferred because they are easy to use and offer rapid results at low cost, but the challenge is that they show lower sensitivity. These tests offer multiple benefits in comparison to RT-PCR tests for the detection of SARS-CoV-2. They have been developed as both laboratory-based tests and for near-patient use (point-of-care). Results are normally generated in 10 to 30 minutes after the start of the analysis, and at low cost. The most currently available rapid antigen test show a lower sensitivity compared to the standard RT-PCR test, while their specificity is generally reported to be high. You need to keep in mind that rapid antigen tests may be sensitive enough to detect cases with a high viral load, such as pre-symptomatic and early symptomatic cases (up to 5 days from symptom onset; or low RT-PCR cycle threshold (Ct) value <25), which likely account for a significant proportion of transmissions.
