This finding illustrates the reliability of tests obtained by adequate self-collected anterior nasal specimen. Sensitivity measures how often a test correctly generates a positive result for the condition being tested. Quidel says its COVID-19 antigen test is now on par with PCR accuracy While the main advantage of rapid antigen detection tests is the immediate availability of results, PCR should be preferred in crucial settings wherever possible. A test's sensitivity is also known as the true positive rate. 2021. hb```@(e# Definitely not to be ignored. Healthcare professionals can purchase the QuickVue SARS Antigen Test through select authorized distributors. The results confirm similar sensitivity of self-collected anterior nasal swabs to that of professionally collected nasopharyngeal swabs for patients with a CT of < 30 determined by RT-PCR.
