A positive outcome from a specific rapid antigen diagnostic test indicates the detection of SARS-CoV-2 antigens. This suggests a likely active infection, though it’s essential to remember that these tests primarily identify the presence of viral proteins, not the virus itself. For instance, a person displaying symptoms consistent with COVID-19 who receives such a positive result is highly likely to be currently infected.
Rapid antigen tests offer readily accessible preliminary diagnostic information. Their speed and convenience make them invaluable tools for timely infection detection, contributing to quicker isolation and reduced transmission rates. This rapid identification can also facilitate prompt access to appropriate medical care and antiviral treatments when necessary. While molecular tests remain the gold standard for diagnostic accuracy, the speed and accessibility of antigen testing have played a crucial role in pandemic management, particularly in situations requiring rapid results.
