Avian Influenza Virus H7 Antigen Test

Short Description:

The Avian Influenza Virus H7 (AIV-H7) is a highly contagious virus primarily affecting birds. In certain cases, it can cross the species barrier and infect humans, causing severe respiratory diseases and even fatalities. The H7 Antigen Rapid Test Cassette is a reliable diagnostic tool designed for the on-site rapid detection of the H7 subtype of avian influenza virus in birds. It is particularly useful for early screening during outbreaks and epidemiological investigations.

This product is designed to be simple and convenient, suitable for use in laboratories, farms, customs inspections, and border disease prevention operations. It provides critical support for the early diagnosis and control of avian influenza.

Principle:

The H7 Antigen Rapid Test is a lateral flow immunochromatographic assay used to detect the presence of H7 antigens in samples such as bird swabs (nasopharyngeal, tracheal) or fecal matter. The test operates based on the following key steps:

Sample Preparation
Samples (e.g., nasopharyngeal swab, tracheal swab, or fecal sample) are collected and mixed with the lysis buffer to release viral antigens.
Immune Reaction
The antigens in the sample bind to specific antibodies conjugated with gold nanoparticles or other markers pre-coated on the test cassette, forming an antigen-antibody complex.
Chromatographic Flow
The sample mixture migrates along the nitrocellulose membrane. When the antigen-antibody complex reaches the test line (T line), it binds to another layer of antibodies immobilized on the membrane, creating a visible test line. Unbound reagents continue migrating to the control line (C line), ensuring the test's validity.
Result Interpretation
- Two lines (T line + C line): Positive result, indicating the presence of H7 antigens in the sample.
- One line (C line only): Negative result, indicating no detectable H7 antigens.
- No line or T line only: Invalid result; the test should be repeated with a new cassette.
