The BinaxNOW® Influenza A & B Test simplifies
rapid influenza testing. The easiest flu test on the market just
got easier with accurate differentiation between influenza A and
influenza B using one simple step on one test. Now you can focus on
the results and treating the patient, not running the
test.
Intended Use
The BinaxNOW® Influenza A & B Test is an in
vitro immunochromatographic assay for the qualitative
detection of influenza A and B nucleoprotein antigens in
nasopharyngeal (NP) swab, nasal swab** and nasal wash/aspirate
specimens. It is intended to aid in the rapid differential
diagnosis of influenza A and B viral infections. Negative test
results should be confirmed.

BinaxNOW® Influenza A & B Testing
Procedure
WARNING: INVALID RESULTS can occur when too
little sample is added to the test. Be sure that the lower part of
the transfer pipette is full and does not have any air spaces
before you add the sample to the sample pad. If there are air
spaces, put the sample back in the container by squeezing the top
bulb. Redraw the sample from the bottom of the container into the
pipette. Use a new pipette if needed.
Remove device from the pouch just prior to testing
and lay flat on work bench.
Fill pipette by firmly squeezing the top bulb
and then placing pipette tip into sample. Slowly
release bulb while tip is still in sample. This will pull liquid
into the pipette. Make sure there are no air spaces in the lower
part of the pipette.
See arrow on test device to find the
WHITE sample pad at the top of the test strip.
SLOWLY (drop by drop) add entire contents of the
pipette (100 µl) to the MIDDLE of this pad such
that all of the sample volume absorbs into this pad. DO
NOT add sample to the pink/purple colored pad.
Immediately peel off adhesive liner from the
test device. Close and securely seal the device. Read result in
window 15 minutes after closing the device. Note: When reading the
results, tilt the device to reduce glare on the result window if
necessary.

About Influenza
Influenza is a highly contagious, acute, viral infection of the
respiratory tract. It is a communicable disease easily transmitted
through the coughing and sneezing of aerosolized droplets
containing live virus. Influenza outbreaks occur each year during
the fall and winter months.1 Each year in the United
States, about 5% to 20% of residents get influenza, and more than
200,000 people have to be hospitalized as a result of
influenza.2 Type A viruses are typically more prevalent
than type B viruses and are associated with most serious influenza
epidemics, while type B infections are usually more mild.
Rapid diagnosis of influenza A and B has become more important
due to the availability of effective antiviral therapy. Rapid
diagnosis of influenza can lead to reduced hospital stays,
antimicrobial use, and cost of hospital care.1
