The BinaxNOW COVID-19 Antigen Self-Test is a rapid test that uses a shallow nasal swab sample to check for the presence or absence of proteins from the virus that causes COVID-19. The culture showed evidence of cytopathic effects and had presence of SARS-CoV-2 RNA as detected by real-time RT-PCR in the first passage culture, but viral recovery was not two Ct values lower than the corresponding clinical specimen Ct.

To perform the test, and anterior nasal swab specimen is collected by the patient, then 6 drops of extraction reagent from a dropper bottle are added to the top hole of the swab well. Do not reuse the used test card or swab. Serial antigen testing can improve detection, but consideration should be given to the logistical and personnel resources needed. Proper sample collection and handling are essential for correct results. Median Ct values for SARS-CoV-2 culture-positive specimens (22.1) were significantly lower than were those for culture-negative specimens (32.8) (p<0.001), indicating higher levels of viral RNA in culture-positive specimens. The BinaxNOW COVID -19 Ag Card 2 Home Test is intended for observed non-prescription self - use and/or, as applicable for an adult lay user testing another person aged 2 years or older in a Sensitivity was higher for culture-positive specimens (92.6% and 78.6% for those from symptomatic and asymptomatic persons, respectively); however, some antigen test-negative specimens had culturable virus.

Specimens with low levels of antigen may give a faint Sample Line. 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. However, a negative result does not rule out COVID-19 and should not be used as the sole basis for treatment or patient management decisions, including infection control decisions.
