Influenza Test

An influenza test detects whether you are infected with the flu virus. It typically involves taking a small sample from your nose or throat using a swab. This sample is then tested in a laboratory or with a rapid test kit to identify the presence of influenza A or B viruses. Results can often be available within minutes to hours. The test helps doctors determine if your symptoms are caused by the flu, so they can recommend appropriate treatment and prevent spreading it to others. Early testing can be especially useful for high-risk individuals and during flu season.
