Molecular Tests: The Gold Standard
Doctors often use molecular tests like RT-PCR to detect flu viruses because they're very accurate. These tests can tell if you have influenza A or B and are especially helpful when both the flu and COVID-19 are spreading.
What Happens During a Flu Test?
A healthcare provider will likely collect a sample from your nose or throat using a swab. This sample is then tested for flu viruses. The whole process might take just a few minutes, although results can take longer.
When Should You Get Tested?
Testing is usually recommended if it will change how you're treated, especially if you're at high risk for complications. This includes people with chronic illnesses or weakened immune systems.
