Why Buy a At-Home Flu Test?
Having access to an influenza test can mean the difference in receiving early treatment antiviral drugs. Studies show that taking an antiviral drug reduces the sickness duration when administered within 48 hours of the onset of flu symptoms.1 Test-to-treat means getting to the next step quickly by taking an influenza antiviral prescription drug. A rapid flu test is particularly helpful and convenient to get this process going because making a trip to a clinic is emotionally and physically challenging when symptoms arise. Another benefit to testing at home is it helps to reduce the incidence of infection by limiting exposure.
How Does the Test Work?
A rapid influenza diagnostic test checks for the presence of the influenza A and B antigens. Although there are four types of flu, influenza A and B are the two main types that cause seasonal flu outbreaks.
Types of Sample Collection
There are multiple ways to collect a sample when using an influenza rapid test. Read the instructions to determine the method as not all tests are the same. Most professional tests allow for the following collection methods:
- Nasal Swab is a cotton-tipped sterile swab to collect a sample from within the nostrils.
- Nasopharyngeal Swab is a flexible wire swab or aspirate that is longer than a nasal swab in order to pass through the nostril to the nasopharynx to collect a deeper sample from the back of the throat.
- Nasopharyngeal Aspirate or nasal wash requires a suction device to collect the specimen and place it into a vial.
Frequently Asked Questions (FAQ)
Can an influenza test give a false negative?
Yes. There are cases when no signs of the virus were found despite the individuals being infected. If symptoms persist after a negative result, another test should be administered.
What may affect a flu test?
The flu is a respiratory infection, so if the test user has another respiratory infection, it can give a false-positive result.
Does the flu test also detect SARS-CoV-2?
No. The symptoms can be similar but the flu test only determines if there is a presence of the influenza A and B antigens.
