With the flu season right around the corner, experiencing flu-like symptoms can make you worry if you’ve caught wind of the virus. The flu is a contagious disease with signs similar to common colds and seasonal allergies.1,2 

Flu testing helps determine if the flu or influenza causes your symptoms. Influenza testing methods like rapid flu tests and molecular assays help detect the influenza virus. 

They use a sample of your nasal swab to check for specific molecules like proteins or genes that may indicate the presence of the influenza virus. 

At-home flu test kits are an easy and accessible way to test for influenza virus infection. Some can even detect other respiratory viruses, like respiratory syncytial virus (RSV) and COVID-19.

How We Picked The Best

Choosing a suitable at-home test kit can be challenging. Many brands are widely available, but we narrowed our list to the three best at-home flu testing. 

We picked our top choices based on these criteria:

  • Food and Drug Administration (FDA) approval
  • Quick turn-around of results 
  • Value for money
  • Insurance acceptance
  • Access to treatment after taking the test

We went through several research studies and reviews to come up with the best choices.

How To Interpret Your At-Home Flu Test Results

A self-collection kit can show if your sample is positive or negative. Inconclusive results may also occur in some cases.

If you purchased a combined testing kit that checks for influenza and other viruses, such as COVID-19, it should provide separate reports for each type.

  • A positive result indicates the presence of the influenza virus in your sample. However, it may not be conclusive of your symptoms. 
  • A negative result means no influenza viruses in your sample

You must contact your doctor for the next steps. They can help you manage your flu infection and lessen your symptoms.

You should still talk to a doctor if you get a negative result. They can assess if you need more tests, especially if your first test was a rapid antigen test.

Rapid diagnostic tests are more likely to produce false negatives.

Are At-Home Flu Tests Accurate?

Using at-home influenza tests to detect influenza infection is common. However, the accuracy of their results depends on various factors, such as:

  • The kind of test – For example, a rapid antigen test has a higher chance of giving false-negative results than molecular tests. It can affect the accuracy of the test.
  • Timing of the test – If you test 3 to 4 days after your initial symptoms, it’ll more likely detect the virus. It’s best to get tested when you have symptoms.
  • Collecting and handling samples – Your results depend on the quality of your sample, especially for self-collection tests. Mishandling them can affect the accuracy of results. 
  • Recent flu vaccination – If you received a flu shot before testing, there’s a chance that you’ll get a false positive result.

When Should You Get A Flu Test?

Doctors recommend flu testing if you have flu-like symptoms. It can help them determine the cause of your symptoms.

You can also take an at-home flu test any time you have symptoms. The doctor might order more tests if you have positive results.

The onset of the flu feels like a common cold with frequent sneezing, runny nose, and sore throat. But unlike colds that slowly develop, flu symptoms usually show up suddenly.3

  • The most common signs of flu are:
  • Fever
  • Chills
  • Cough
  • Sore throat
  • Runny nose
  • Muscle or body pains
  • Headaches
  • Fatigue

Key Takeaway

At-home tests like LetsGetChecked Coronavirus Test (COVID-19) and Labcorp COVID-19 + Flu PCR Test can help your doctor confirm a flu diagnosis

In addition, testing at home lowers the risk of spreading the virus to others. 

Early detection of the flu virus can help prevent it from spreading to people you frequently interact with — like household members and co-workers.

After taking an at-home flu test, you must discuss treatment options with your doctor. In some cases, they may require further testing for other conditions like respiratory tract infection.

Since the flu is a viral infection, your doctor may prescribe antiviral drugs to lessen your symptoms. These medications can also speed up your recovery and prevent complications like pneumonia.

Besides taking care of yourself, you must be careful around other people. 

If you feel sick, these tips will prevent you from spreading the infection:

  1. Limit your contact with others to avoid infecting them.
  2. Wear a medical mask at all times.
  3. Cover your nose and mouth with a tissue when coughing or sneezing.
  4. Throw away used tissues in the trash.
  5. Wash your hands often with soap and water.
  6. Disinfect your surroundings, especially hard surfaces.
  7. Stay at home until you feel better.

Consider getting annual flu vaccines and a COVID vaccine. It can protect you and your loved ones from the flu and its health complications.
