Fight Back Against RSV and Flu A/B with Early Testing
Did you know? The major winter illness is respiratory syncytial virus (RSV), which causes around 30,000 hospitalisations of children under 5 each year in the UK. Meanwhile, Flu A accounts for 75% of cases and is usually more serious in adults than Flu B, which is still significant despite its low incidence.

Why Should You Take the Flu and RSV Test?
Testing for Influenza (Flu A and B) and Respiratory Syncytial Virus (RSV) is crucial for understanding respiratory health, preventing complications, and managing potential outbreaks. These viruses are significant causes of respiratory illness, particularly during the winter months. Here’s why this test is essential:
-
Identify the Respiratory Symptom Cause:
Detect whether your symptoms are from Flu A, Flu B or RSV for accurate treatment and care.
-
Prevent the Spread:
Early detection lowers the risk of transmission - especially to children, the aged or persons with impaired immune systems.
-
Monitor Severe Conditions:
RSV causes bronchiolitis or pneumonia and Influenza A (H3N2) causes serious illness and death. Early detection blocks escalation.
-
Plan Treatment Effectively:
Choose between different viruses to avoid unnecessary medications or antibiotics.
Symptoms Indicating the Need For RSV and Influenza Testing
Both Respiratory Syncytial Virus and Influenza A and B have overlapping symptoms that must be tested and diagnosed. Testing helps guide appropriate treatment and reduces complications, especially in high-risk groups such as children, the elderly or those with weaker immune systems. The top symptoms to watch out for:
-
Sudden Onset of High Fever (Influenza)
An extreme rise in body temperature often with chills is characteristic of influenza.
-
Cough (Both)
Persistent and occasionally dry for influenza or with wheezing in RSV cases.
-
Runny Nose (RSV)
Nasal passage inflammation and infection are common symptoms of RSV.
-
Myalgia (Influenza)
Usually severe and widespread muscle aches and body pain accompany the flu.
-
Wheezing (RSV)
The sound of whistling when breathing, usually in young children or people with respiratory issues.
-
Sore Throat (Influenza)
Throat discomfort/pain - often difficult to swallow.
-
Headache and Severe Malaise (Influenza)
Intense fatigue, general unwellness, and headache that impact daily functioning.
How and What We Measure
We utilise advanced rapid antigen detection tests to identify the presence of Influenza A, Influenza B, and Respiratory Syncytial Virus (RSV) antigens in nasal swab specimens. These tests identify viral proteins specific to those infections. The resultant rapid identification of the viruses for timely clinical decision making reduces risk of complications and transmission, with results in just 15 minutes. complications and transmission, with results in just 15 minutes.
-
Influenza A and B viruses along with RSV are major respiratory pathogens. Surface antigens - haemagglutinin (H) and neuraminidase (N) - define influenza viruses. RSV attacks the lower respiratory tract and is more severe in infants and the elderly. Detection of such markers provides information regarding disease severity and therapeutic strategy.
-
Rapid antigen testing has several key benefits when managing respiratory infections:
Quick Turnaround: Results are delivered within about 15 minutes for immediate diagnosis and care planning.
Point-of-Care Application: They may be done in clinics or hospitals without a laboratory.
Early Detection: Early identification of infections allows isolation and treatment of infections reducing outbreak risk and transmission to vulnerable populations.
Cost-Effective: In contrast to more sophisticated diagnostic methods, rapid antigen tests are inexpensive and widely available.
-
Rapid antigen tests are effective but have their limits:
Variable Sensitivity: These tests could be less sensitive than molecular methods like RT-PCR for low viral loads or asymptomatic cases.
False Negatives: Positive results in symptomatic individuals may need additional confirmation with more sensitive methods.
Specificity for Active Infection: Rapid antigen tests identify infections today but not previous exposure/immunity.
-
1
This test requires no special preparation. You may eat and drink as usual before coming to your appointment.
-
2
Trained healthcare professionals will gently collect a nasal swab sample. This is a quick process meant to minimize discomfort.
-
3
This sample is then transferred to an advanced machine for analysis for the presence of RSV and Influenza a or B antigens.
-
4
Analyses take about 15 minutes. You may then relax in a waiting area during this time.
-
5
The results will indicate whether you are positive or negative for RSV, Influenza A, or Influenza B. Your healthcare provider will explain the findings and what they mean for Your health.
-
6
Depending on your results, your healthcare provider may order additional diagnostic tests, prescribe medication or advise you on managing symptoms and preventing spread of the infection.
