Influenza

The Influenza Test, (Influenza A+B rapid test) is a rapid chromatographic immunoassay for the qualitative detection of influenza A and B antigens in nasopharyngeal swab, throat swab or nasal aspirate specimens. It is intended to aid in the rapid differential diagnosis of influenza A and B viral infections. 

Influenza (commonly known as ‘flu’) is a highly contagious, acute viral infection of the respiratory tract. It is a communicable disease easily transmitted through the coughing and sneezing of aerosolised droplets containing live virus.1 Influenza outbreaks occur each year during the autumn months. 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 milder. The gold standard of laboratory diagnosis is 14-day cell culture with one of a variety of cell lines that can support the growth of influenza virus.2 Cell culture has limited clinical utility, as results are obtained too late in the clinical course for effective patient intervention.

Reverse Transcriptase Polymerase Chain Reaction (RT-PCR) is a newer method that is generally more sensitive than culture with improved detection rates over culture of 2-23%.3 However, RT-PCR is expensive, complex and must be performed in specialised laboratories. The Influenza Test, (Influenza A+B rapid test) qualitatively detects the presence of Influenza A and/or Influenza B antigen in nasopharyngeal swab or throat swab or nasal aspirate specimens, providing results within 15 minutes. 

The Influenza Test, (Influenza A+B rapid test) is a qualitative, lateral flow immunoassay for the detection of Influenza A and Influenza B nucleoproteins in nasopharyngeal swab, throat swab or nasal aspirate specimens. In this test, antibodies specific to the Influenza A and Influenza B nucleoproteins are separately coated on the test line regions of the test dipstick. During testing, the extracted specimen reacts with the antibody to Influenza A and/or Influenza B that are coated onto particles. The mixture migrates up the membrane to react with the antibody to Influenza A and/or Influenza B on the membrane and generates one or two coloured lines in the test regions. The presence of this coloured line in either or both of the test regions indicates a positive result. To serve as a procedural control, a coloured line will always appear in the control region if the test has performed properly.

Aftercare 

If your test is positive, it is highly likely you have the flu. You do not need to contact your GP unless your symptoms become severe eg breathing difficulty or temperature above 39 degrees for more than 3 days or if you are on the highly vulnerable list. You can treat fever and general aches with paracetamol and plenty of fluids. Please avoid other paracetamol based medications while using paracetamol. Please do not exceed the recommended daily dosage of 2 tablets every 4 hours with a maximum of 8 in 24 hours. If you are worried at any time please contact your own GP or 111. For further advice. 

If your recent test for Influenza is negative. It is likely you were not infected with influenza at the time of your test. It is common for many viruses to give symptoms similar to influenza. These symptoms such as fever, fatigue, aches and pains can be relieved with simple over the counter remedies such as paracetamol. Please seek advice at your local pharmacy. Please ensure you take a Covid-19 lateral flow test as Covid -19 should be out ruled. If you are concerned about worsening symptoms please call your own GP/111.
