CDIATM Human Influenza A+B Rapid test (DTSXYZ10)

Intended Use

The Influenza A+B test is a rapid chromatographic immunoassay for the qualitative detection of Influenza type A (including subtypes A/H1N1, A/H3N2, A/H5N1) and type B antigens in human nasopharyngeal specimens to aid in the diagnosis of Influenza infection.

Product Introduction

General Description

Although a wide variety of viral agents are capable of causing lower respiratory tract infections in children and adults, influenza A & B; respiratory syncytial virus (RSV); parainfluenza viruses 1, 2, and 3; and adenovirus are the most common. Of these, influenza A & B and RSV are the most important causes of medically attended acute respiratory illness. In addition to sharing a similar seasonal prevalence, it is important to remain cognizant that influenza A & B and RSV share overlapping clinical features and infection potential for certain high-risk patient groups (e.g., extremes of age, underlying cardiopulmonary disease and immunosuppression).


The Influenza A+B Rapid test is a qualitative lateral flow immunoassay for the detection of Influenza type A and type B antigens in human nasopharyngeal samples. The membrane is pre-coated with monoclonal antibodies against Influenza type A and type B antigens on the test line regions. During testing, the sample reacts with the particle coated with anti-Influenza antibodies which was pre-dried on the test strip. The mixture moves upward on the membrane by capillary action. In the case of a positive result the specific antibodies present on the membrane will react with the mixture conjugate and generate one or two coloured lines. A green coloured line always appears in the control line and serves as verification that sufficient volume was added, that proper flow was obtained and as an internal control for the reagents.
