About this test – 4-in-1 Influenza Test

Key Benefits

• No Lab Return Needed: Get a visual result without sending a sample to a laboratory

What This Test Measures

The 4-in-1 Influenza Test screens for antigens from common respiratory viruses in a nasal swab:

COVID-19: A respiratory infection caused by SARS-CoV-2. It may cause fever, cough, sore throat, tiredness, headache, nasal congestion, body aches or changes in taste and smell.

Influenza A/B: Influenza, often called flu, can come on suddenly and may cause fever, chills, cough, sore throat, muscle aches and strong tiredness. This test includes both Influenza A and Influenza B.

RSV: A common respiratory virus that often causes cold-like symptoms such as cough, runny nose, sneezing, fever and general illness. RSV can be more significant for young children, older adults and people with certain health conditions.

Adenovirus: A virus that can cause cold-like respiratory symptoms such as sore throat, cough, fever and nasal congestion. Some adenoviruses may also affect the eyes or gastrointestinal tract.

Why Respiratory Testing Matters

Many respiratory infections look alike in the beginning. A negative COVID-19 test alone does not tell you whether symptoms could be linked to flu, RSV or adenovirus.

A broader test can help you understand the situation faster. This can be especially helpful during periods when several viruses are circulating, when you are around vulnerable people, or when you want to reduce the risk of spreading infection to others.

The test is intended as an initial screening tool and does not replace medical diagnosis or professional guidance.

How It Works

1. Collect Your Sample
Take a nasal swab sample according to the included instructions.

2. Prepare the Test
Place the swab into the buffer tube and mix the sample with the provided buffer solution.

3. Add the Sample
Add the required drops of solution to the test cassette.

4. Wait for the Result
Allow the test to develop for approximately 10 minutes.

5. Read Your Result
Interpret the result lines according to the included guide.

Sample Collection

The test uses a nasal swab sample. The swab is inserted into the nose and rotated according to the instructions provided with the kit. The same swab is used for both nostrils.

The swab is then mixed with the buffer solution, and drops are added to the test cassette.

Results are read visually after approximately 10 minutes.

The test was previously called the 4-in-1 Respiratory Test. The product and test content remain the same, only the name has been updated to 4-in-1 Influenza Test.

Biomarkers included – 4-in-1 Influenza Test

• RSV Antigen: RSV Antigen refers to specific proteins found on the surface of the Respiratory Syncytial Virus. Detecting these antigens is a rapid and direct way to confirm the presence of an active RSV infection, which is crucial for guiding treatment and public health measures.
• Influenza A Antigen: The Influenza A Antigen is a specific component, usually a viral protein, found on the surface or within the influenza A virus. Detecting this antigen is crucial for quickly identifying whether an infection is caused by influenza A, allowing for prompt diagnosis and appropriate treatment or management.
• Adenovirus Antigen: Adenovirus antigen is a specific protein or part of the adenovirus virus itself. Detecting these antigens can indicate an active adenovirus infection, helping healthcare providers diagnose illness and guide treatment.
• SARS-CoV-2 Antigen: SARS-CoV-2 antigen refers to specific proteins that are part of the SARS-CoV-2 virus, the pathogen responsible for COVID-19. Detecting these viral proteins indicates the presence of the virus itself, meaning an individual is actively infected and can potentially spread the virus.
• Influenza B Antigen: Influenza B Antigen is a specific protein or part of the Influenza B virus itself. Detecting its presence in a sample, typically from a respiratory swab, indicates an active Influenza B infection. This is crucial for timely diagnosis and appropriate treatment decisions.

How to prepare – 4-in-1 Influenza Test

Wash and dry your hands before performing the test. Use the test on a clean, flat surface and make sure the test cassette, buffer and sample are at room temperature before testing. Do not touch the soft tip of the swab. Follow the instructions carefully and read the result within the stated time window.

Frequently asked questions – 4-in-1 Influenza Test

Why test for several respiratory infections at once?

COVID-19, flu, RSV and adenovirus can cause very similar symptoms. Testing several infections at once gives broader information than testing for only one virus.

What does a negative result mean?

A negative result means that the tested virus antigens were not detected in the sample. It does not fully rule out infection, especially early in illness or if the virus level is low.

When can the 4-in-1 Influenza Test be useful?

The test can be useful when symptoms such as fever, cough, sore throat, tiredness, runny nose or body aches appear, especially during cold and flu season or when respiratory infections are spreading among people around you.

Does the test include both Influenza A and Influenza B?

Yes. The test screens for both Influenza A and Influenza B, as well as COVID-19, RSV and Adenovirus.

Why can it be difficult to tell these infections apart from symptoms alone?

COVID-19, influenza, RSV and adenovirus can all cause similar respiratory symptoms, including cough, fever, sore throat, tiredness and nasal symptoms. This can make it difficult to identify the likely cause based on symptoms alone.

Who can be more vulnerable to RSV?

RSV often causes cold-like symptoms, but it can be more significant for young children, older adults and people with certain health conditions.

Can adenovirus cause symptoms outside the respiratory system?

Yes. Some adenoviruses can also affect the eyes or gastrointestinal tract, in addition to causing respiratory symptoms.

Does the sample need to be sent to a laboratory?

No. The test is performed using a nasal swab at home, and the result can be read visually after approximately 10 minutes. No laboratory sample return is required.

Customer reviews – 4-in-1 Influenza Test

4.4/5 (12)

• 5/5 — Fast and easy. Nice not to have to guess if it's the flu or corona when you're feeling sluggish. The instructions were clear enough.
• 4/5 — Quite an okay test that covers the most important things. A bit fiddly with the nasal sampling but it worked out in the end. The result came quickly afterwards.
• 4/5 — Bought this to have at home in case the kids get sick. Very nice to be able to test for RSV and adenovirus at the same time as covid. However, delivery took one day longer than I had hoped for.
• 5/5 — Very clear how to do it and the answer came almost immediately. good that you don't have to send it in anywhere.
• 3/5 — worked well but the box was a bit dented when it arrived.. the contents were intact though, luckily. easy to read the result.
• 5/5 — Good supplement during the flu season. I appreciate that it's a 4-in-1 test so you get a broader picture of the situation right at the kitchen table. The price feels reasonable for what you get.
• 5/5 — Great to have the peace of mind of testing for four things at once.
• 5/5 — Fast delivery and much better than buying separate tests for everything.
