SARS-CoV-2 rapid antigen testing in the healthcare sector: A clinical prediction model for identifying false negative results.

Objectives: SARS-CoV-2 rapid antigen tests (RAT) provide fast identification of infectious patients when RT-PCR results are not immediately available. We aimed to develop a prediction model for identification of false negative (FN) RAT results.

Methods: In this multicenter trial, patients with documented paired results of RAT and RT-PCR between October 1 2020 and January 31 2021 were retrospectively analyzed regarding clinical findings.
