For Prescription Home Use
INTENDED USE
The BinaxNOW
™
COVID-19 Ag Card Home Test is a lateral flow immunoassay intended for the qualitative detection
of nucleocapsid protein antigen from SARS-CoV-2. This test is authorized for prescription home use with self-collected
observed direct anterior nasal (nares) swab samples from individuals aged 15 years or older who are suspected of COVID-19
by their healthcare provider within the first seven days of symptom onset or adult collected nasal swab samples from
individuals aged four years or older who are suspected of COVID-19 by their healthcare provider within the first seven
days of symptom onset. The BinaxNOW COVID-19 Ag Card Home Test is to be performed only with the supervision of
a telehealth proctor.
The BinaxNOW COVID-19 Ag Card Home Test does not dierentiate between SARS-CoV and SARS-CoV-2.
Results are for the identification of SARS-CoV-2 nucleocapsid protein antigen. Antigen is generally detectable in anterior
nasal (nares) swabs during the acute phase of infection. Positive results indicate the presence of viral antigens, but clinical
correlation with patient history and other diagnostic information is necessary to determine infection status. Positive results
do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of
disease.
Negative results should be treated as presumptive and confirmation with a molecular assay, if necessary, for patient
management, may be performed. Negative results do not rule out SARS-CoV-2 infection and should not be used as the
sole basis for treatment or patient management decisions including infection control decisions. Negative results should
be considered in the context of a patient’s recent exposures, history and the presence of clinical signs and symptoms
consistent with COVID-19.
Individuals who test negative and continue to experience COVID-like symptoms should seek follow up care from their
healthcare provider.
BinaxNOW COVID-19 Ag Card Home Test is only for use under the Food and Drug Administration’s Emergency Use
Authorization.
All prescribing healthcare providers will report all test results they receive from individuals who use the authorized product
to relevant public health authorities in accordance with local, state, and federal requirements using appropriate LOINC and
SNOMED codes, as defined by the Laboratory In Vitro Diagnostics (LIVD) Test Code Mapping for SARS-CoV-2 Tests
provided by CDC.
SUMMARY and EXPLANATION of the TEST
Coronaviruses are a large family of viruses which may cause illness in animals or humans. SARS-CoV-2 is an enveloped,
single-stranded RNA virus of the β genus. The virus can cause mild to severe respiratory illness and has spread globally,
including the United States.
The BinaxNOW COVID-19 Ag Card Home Test is a rapid lateral flow immunoassay for the qualitative detection of
SARS-CoV-2 directly from nasal swabs, without viral transport media. The BinaxNOW COVID-19 Ag Card Home Test kit
contains all components required to carry out an assay for SARS-CoV-2.
PRINCIPLES of the PROCEDURE
The BinaxNOW COVID-19 Ag Card Home Test is an immunochromatographic membrane assay that uses highly sensitive
antibodies to detect SARS-CoV-2 nucleocapsid protein from nasal swab specimens. SARS-CoV-2 specific antibodies and
a control antibody are immobilized onto a membrane support as two distinct lines and combined with other reagents/pads
to construct a test strip. This test strip and a well to hold the swab specimen are mounted on opposite sides of a cardboard,
book-shaped hinged test card.
To perform the test, a nasal swab specimen is collected under observation by or from the patient, then 6 drops of extraction
reagent from a dropper bottle are added to the top hole of the swab well. The patient sample is inserted into the test card
through the bottom hole of the swab well, and firmly pushed upwards until the swab tip is visible through the top hole. The
swab is rotated 3 times clockwise and the card is closed, bringing the extracted sample into contact with the test strip. Test
results are interpreted visually at 15 minutes based on the presence or absence of visually detectable pink/purple colored
lines. Results should not be read after 30 minutes.
