Detailed Description
 


One Step Influenza A&B Test is a rapid qualitative assay that detects influenza type A&B

INTENDED USE

One Step Influenza A&B Test is a rapid qualitative assay that detects influenza type A (including the subtype H1N1) and B nucleoprotein antigens extracted from the nasal swab specimen. These device is used to aid in the differential diagnosis of influenza type A and B infection.

 

PRINCIPLE

 

One Step Influenza A&B Test is a rapid immunochromatographic test for the visual detection of influenza type A and B antigens(nucleoprotein) extracted from the nasal swab specimen. The test adopts double antibody sandwich method.

 

When the extracted specimen is added into the test device, the specimen is absorbed into the device by capillary action, mixes with antibody-dye conjugate, and flows across the pre-coated membrane, in which influenza type A and B monoclonal antibodies are coated respectively.

 

When the influenza type A antigen levels are at or above the target cutoff (the detection limit of the test), type A antigen in the specimen binds to the specific antibody-dye conjugate and are captured by influenza type A monoclonal antibody immobilized in the relative site of test region 2 of the device. This produces a colored test band in the test region 2. When the influenza type A antigen levels are zero or below the target cut off, there is not a visible colored band in the test region 2 of the device. This indicates a negative result for influenza type A.

 

When the influenza type B antigen levels are at or above the target cutoff (the detection limit of the test), type B antigen in the specimen binds to the specific antibody-dye conjugate and are captured by influenza type B monoclonal antibody  immobilized in the relative site of test region 1 of the device. This produces a colored test band in the test region 1. When the influenza type B antigen levels are zero or below the target cut off, there is not a visible colored band in the test region 1 of the device. This indicates a negative result for influenza type B.

 

To serve as a procedure control, a colored line will appear at the control region (C), if the test has been performed properly.

Accuracy

 

A comparison study of  One Step Influenza A&B Test and another commercial influenza test (Colloidal gold method) was carried out in several medical institutions. Nasal swab samples were collected from adult and child patients exhibiting influenza-like symptoms. One swab was used to perform the One Step Influenza A&B Test and one swab was used for another commercial influenza test analysis.

 

Compare the sensitivity and specificity between the two tests. The results for detection of influenza A are summarized in Table 1 and the results for detection of influenza B are summarized in Table 2.
