One Step Influenza A＆B Ag Test

One Step Influenza A＆B Ag Test
Intended Use
Influenza A＆B Ag Test is the chromatographic assay used for qualitative detection of influenza virus type A and B nucleoprotein antigens in human nasopharyngeal swab specimens.

Produt name:Influenza A＆B Ag Test
Specimen:Nasopharyngeal swab specimen
Format:Cassette
Model No.:B300-20
Specimen Preparation
1.The collection method of nasopharyngeal swab is shown in Figure 1 to 4.
Figure 1.Remove a nasopharyngeal swab from the pouch.
Figure 2.Place the swab into one of patient s nostrils until reaches the
posterior nasopharynx.
Figure 3.Slowly rotate the swab 3-5 times over the surface of the
posterior nasophanynx.
Figure 4.Remove the swab from the nasalcavity.
2.Sample processing:
Figure 5. Insert the swab in collection tube to the bottom,rotate
and squeeze the swab 10 times.
Figure 6. Leave the swab in the collection tube for 1 minute.
Figure 7. Rotate and squeeze the swab 3 times.
Figure 8. Take out and discard the swab.The retained liquids will be tested with Influenza A＆B Ag Test.

Test Procedure
Read the instruction first prior to testing.Bring the pouched test to room temperature prior to testing.Do not open the pouch until ready to begin testing.
1.Remove the test from the sealed pouch. Lay it on a flat, clean and dry surface.
2.Place the test cassette on a flat and clean surface. Using the provided pipette, add 3 drops retained solution to the sample well.
3.Read results within 10-15 minutes.

INTERPRETATION OF RESULTS
Influenza A Positive: Control line (C) and Test line T1 appear in the show window.
Influenza B Positive: Control line (C) and Test line T2 appear in the show window.
Influenza A＆B Positive: Control line (C) and Test lines T1, T2 appear in the show window.
Negative: Only one line appears in Control area (C), no line appears in T1 and T2 areas.
Invalid: If no line appears in the control area (C), the test results are
invalid regardless of the presence or absence of line in the test area. The
direction may not been followed correctly or the test may be deteriorated.
It is recommended that repeat the test using a new device. If the problem persist, please stop to use the product and contact local distributor.

Sensitivity:The minimum detection limit is 1.5 x 10? TCID50 /test for the Influenza A virus antigen and is 1.5 x 10? TCID50 /test for the Influenza B virus antigen.
Quick Result :Read results within 10-15 minutes.
