How Is an Influenza Test Performed?

An influenza test, also known as a flu test, is performed to determine whether a person has been infected with the influenza virus. There are two main types of influenza tests: rapid influenza diagnostic tests (RIDTs) and molecular tests.

1.Rapid Influenza Diagnostic Tests (RIDTs):

Procedure: A healthcare provider collects a sample by swabbing the back of the person’s throat or nose.
Test Time: The sample is then mixed with a solution and applied to a test strip or cartridge.
Results: The results are usually available within 15-30 minutes. However, these tests may have a higher chance of false negatives.

2. Molecular Tests:

Procedure: A healthcare provider collects a sample by swabbing the back of the person’s throat or nose, similar to RIDTs.
Test Time: The sample is then sent to a laboratory where it is tested using a technique called polymerase chain reaction (PCR).
Results: PCR tests are highly accurate and can detect even small amounts of the influenza virus. However, the results may take several hours or days to be available.

It’s important to note that the specific procedures and techniques used for influenza testing may vary depending on the healthcare provider and the testing facility. If you suspect you have influenza, it’s best to consult with a healthcare professional for proper diagnosis and guidance.
