Influenza A/B RNA

Influenza RNA viruses cause a highly contagious respiratory illness that can occur in children or adults of any age.

Influenza A and B are the strains that most commonly infect humans, with subtypes of Influenza A H1N1 and H3N2 commonly circulating. H3N2 viruses can be associated with more severe disease and increased mortality.

Influenza occurs more often in the winter months and is spread easily from person to person. Complications of infection are more likely in the very young, older adults, pregnant women, and people who have certain health problems such as asthma or other forms of lung disease.

Rapid detection of influenza virus is important to guide effective treatment.

Clinical Details

Influenza viruses are typically associated with infections of the upper respiratory tract causing mild to severe illness. Symptoms include fever, cough, headache, myalgia or malaise. Transmission is from person to person and is spread by aerosolization, droplet or direct contact with respiratory secretions. The incubation period is 1-4 days and the period of infectivity is 1-2 days before to up to 5 days of symptom onset.

Annual vaccination is advised in high risk groups. Information on the HSE National Immunisation guidelines can be viewed HERE.

Transporting
Samples

In addition to the packaging of samples, the transport/delivery of clinical samples to the laboratory is required to be in adherence to all national regulations for the safe transport of biological materials. Enfer Medical provides a fully compliant logistics service, aligned with clients’ testing requirements.

Prompt transport of specimens:
To ensure prompt testing of samples and release of results within the published test turnaround times, samples should arrive to the laboratory by 18:00. Test turnaround time is measured from receipt of the sample at the laboratory until the time the authorised results are reported to users.

Acceptance/Rejection
of Samples

In rare cases specimens may not be suitable for testing on arrival to the laboratory. In that case the sample will be rejected at the receipt stage and the service user will be notified immediately and an explanation as to why the sample could not be processed will be provided. Reasons why samples cannot be processed include but are not limited to:

  • Samples received beyond the stability limits and/or not at the correct temperature indicated for each test.
  • Incorrect sample type received.
  • Leaking samples, sample not received or sample insufficient for analysis as stated below within sample requirements.
  • Non-compliant samples or request forms i.e. those missing sample date information, missing sample test request and/or missing sample site/type information.
  • Samples received without the necessary patient identifiers.
Clients will be provided with guidance on Sample Receipt Anomalies.
