rapid testing methods

Rapid testing methods are diagnostic tools that quickly detect the presence of a virus or disease, often providing results within minutes to hours. They typically work by identifying specific components, like proteins or genetic material, of the pathogen. Examples include rapid COVID-19 antigen tests and some pregnancy tests. These tests are useful for quick screening, guiding immediate decisions, and controlling the spread of illness, although they may be slightly less sensitive than laboratory-based tests. Overall, rapid tests deliver prompt, actionable results, helping with timely medical or public health responses.
