This product

Description

Flu A/B + COVID-19 Self-Test is a convenient at-home nasal swab test designed to detect and differentiate SARS-CoV-2, Influenza A and Influenza B antigens from a single sample. Instead of relying on symptoms alone — which can be very similar across COVID-19 and seasonal flu — the test provides separate results for all three viruses in approximately 15 minutes.

Everything required for testing is supplied, with no laboratory equipment needed. The nasal sample is mixed with the supplied extraction solution before four drops are added to the test cassette. A control line confirms that the test has performed correctly, while individually labelled COVID-19, Flu A and Flu B lines allow you to identify which viral antigen has been detected.

Important: this is an antigen test intended to aid diagnosis in people with symptoms, particularly during the first seven days of illness. A negative result does not completely rule out COVID-19 or influenza, particularly when viral levels are low. A reactive result should be considered alongside your symptoms and, where clinically appropriate, confirmed through a healthcare professional or alternative testing method. Seek medical advice if you are particularly unwell, short of breath, at increased risk of complications or your symptoms are not improving.

For other at-home testing needs, the wider range also includes fertility testing, hormone tests and pregnancy tests.

What's inside

Each test contains:

1 x COVID-19/Flu A&B Rapid Test Cassette
1 x Sterile nasal swab
1 x Extraction tube with buffer
1 x Dropper tip
1 x Instructions for Use

How it works

Read the enclosed Instructions for Use completely before beginning and wash and dry your hands.

Using the supplied sterile swab, carefully insert the tip into one nostril until gentle resistance is felt. Rotate the swab 5 times against the inside of the nostril, then repeat in the other nostril using the same swab.

Insert the swab into the extraction tube containing the buffer. Rotate it at least 6 times, pressing the swab head against the bottom and sides of the tube, then leave it in the solution for 1 minute.

Squeeze the sides of the tube while removing the swab, then securely attach the dropper tip.

Place the test cassette on a clean, flat surface and add 4 drops of the extracted sample into the sample well.

Wait 15 minutes before reading the result. Do not interpret the test after 20 minutes.

A visible control line (C) is required for a valid test. Refer to the supplied result guide to identify COVID-19, Flu A or Flu B positive results. If the control line does not appear, the test is invalid and should be repeated using a new test.

What does the Flu A/B + COVID-19 Self-Test detect?

It detects and differentiates SARS-CoV-2, Influenza A and Influenza B nucleocapsid antigens from a nasal swab sample, helping identify which of these respiratory viruses may be responsible for your symptoms.

How quickly will I get my result?

Results should be read after 15 minutes. Do not interpret the test after 20 minutes, as results outside the specified reading window may be unreliable.

Can one test distinguish between COVID-19 and flu?

Yes. The test cassette has separate indicators for COVID-19, Influenza A and Influenza B, allowing the three viral antigens to be differentiated from the same nasal sample.

When is the best time to use the test?

The femme Health product information states that the test is intended for people who are symptomatic within the first seven days of illness, when respiratory viral antigens are more likely to be detectable.

What does a positive Flu A or Flu B result mean?

A positive Influenza A or Influenza B result means the corresponding viral antigen has been detected and it is likely that you have that type of flu. Test results should be considered alongside your symptoms and medical history.

What should I do if I test positive for COVID-19?

A positive rapid antigen result means it is very likely that you have COVID-19. Current NHS guidance advises adults with a positive result to try to stay at home and avoid contact with other people for 5 days after the day the test was taken. Take particular care to avoid contact with people at increased risk of becoming seriously unwell.

Can I still have flu or COVID-19 if the test is negative?

Yes. A negative antigen result does not completely rule out infection. Viral antigen levels can be too low to detect, particularly depending on when you test. If symptoms persist, worsen or you remain concerned, seek medical advice and consider whether repeat or alternative testing is appropriate.

When should I seek medical advice for flu symptoms?

Contact your GP or NHS 111 if you feel very unwell, are short of breath, your symptoms are not improving after 7 days, or you are at greater risk of complications — including during pregnancy, from age 65, with certain long-term conditions or with a weakened immune system.
