Among the 224 specimens undergoing viral culture that were analyzed with the CDC 2019-nCoV Real-Time RT-PCR Diagnostic Panel for detection of SARS-CoV-2, median Ct values** were significantly higher for specimens with false-negative BinaxNOW antigen test results, indicating lower viral RNA levels than in those with concordant positive results (33.9 versus 22.0 in specimens from symptomatic persons [p<0.001] and 33.9 versus 22.5 in specimens from asymptomatic persons [p<0.001]) (Figure). Cross-reactivity and potential interference of BinaxNOW COVID-19 Antigen Self Test was evaluated by testing 37 commensal and pathogenic microorganisms (8 bacteria, 14 viruses, 1 yeast, and pooled human nasal wash) that may be present in the nasal cavity. For P. jirovecii one area of sequence similarity shows 45% homology across 18% of the sequence, making cross-reactivity in the BinaxNOW COVID-19 Antigen Self Test highly unlikely.

Lower Ct values represent higher levels of viral RNA in the specimen and higher Ct values represent lower levels of viral RNA. The BinaxNOW COVID-19 Antigen Self Test is an immunochromatographic membrane assay that uses highly sensitive antibodies to detect SARS-CoV-2 nucleocapsid protein from direct anterior nasal swab specimens. Corresponding author: Jessica L. Prince-Guerra, yov0@cdc.gov. Emerg Infect Dis 2020;26:165465. 360bbb-3(b)(1), unless the authorization is terminated or revoked sooner. Test performance depends on the amount of virus (antigen) in the sample and may or may not correlate with viral culture results performed on the same sample. Results should not be read after 30 minutes. Antigen tests are great at detecting highly infectious people. Clin Infect Dis 2020. The test can be used for people with and without symptoms. If the patient is experiencing nasal congestion, have them blow his/her nose before swabbing. The first-of-its-kind app, available at no charge, allows people who test negative to get a temporary digital health pass that's renewed each time the person has a negative test.

Individuals who test positive with the BinaxNOW COVID-19 Antigen Self Test should self-isolate and seek follow-up care with their physician or healthcare provider as additional testing may be necessary. Following the instructions, the patient drops six drops of reagent fluid onto the test card where indicated. At both sites, a health care professional first collected a bilateral anterior nasal swab, using a swab provided in the BinaxNOW kit, immediately followed by a bilateral nasopharyngeal (NP) swab for real-time RT-PCR testing. Additional confirmatory sting with a molecular test for positive results may also be necessary if there is a low likelihood of COVID-19, such as in individuals without known exposures to COVID-19 or residing in communities with a low prevalence of infection. We have developed twelve tests for COVID-19 globally.

All rights reserved.All trademarks referenced are trademarks of either the Abbott group of companies or their respective owners.IN195150 Rev. Viral recovery was defined as any culture in which the first passage had an N1 Ct value at least two Ct values lower than the corresponding clinical specimen. Positive results do not rule out bacterial infection or co-infection with other viruses. To evaluate the performance of the BinaxNOW rapid antigen test, it was used along with real-time reverse transcriptionpolymerase chain reaction (RT-PCR) testing to analyze 3,419 paired specimens collected from persons aged 10 years at two community testing sites in Pima County, Arizona, during November 317, 2020. Therefore, negative results in patients with symptom onset greater than seven days should be interpreted with caution, as the sensitivity of the assay decreases over time. A negative test result may occur if the level of antigen in a sample is below the detection limit of the test. A questionnaire capturing demographic information and current and past14-day symptoms was administered to all participants. For participants who were within 7 days of symptom onset, the BinaxNOW antigen test sensitivity was 71.1% (95% CI = 63.0%78.4%), specificity was 100% (95% CI = 99.3%100%), PPV was 100% (95% CI = 96.4%100%), and NPV was 92.7% (95% CI = 90.2%94.7%). The Reagent Solution contains a harmful chemical (see table below). Negative results are presumptive, do not rule out COVID-19 infection and it may be necessary to obtain additional testing with a molecular assay if needed for patient management. They are highly portable, scalable, easy-to-use and provide a flexible approach to helping more people in more places get access to reliable testing in a cost effective way.
