Abstract:
Aim: Rapid detection is crucial in complementing vaccination to reduce transmission of SARS-CoV-2. Materials & methods: Nasopharyngeal swabs (n = 213) and oropharyngeal swabs (n = 98) were tested. with the antigen rapid test kit. Results: Overall sensitivity (97.96%), specificity (100.00%) and coincidence rate (98.71%) were high, which translated into a positive predictive value of 100.00% and a negative predictive value of 96.64%. Conclusion: Antigen rapid tests have a great potential for screening in different settings to deliver results with high sensitivity and specificity.
