COVID-19 rapid PoC (point-of-care) testing refers to a test which can be self-administered at home by a potentially sick and/or exposed person by swabbing your nasal passage. It tests for the SARS-CoV-2 nucleocapsid protein antigen, and is meant to be a fast, cheap, and relatively effective test to alert an individual that they are sick (regardless of their specific symptoms) with COVID-19.
