Experiencing symptoms such as fever, cough, sore throat, body aches, and fatigue during flu season? An Influenza A & B (Flu) test can help diagnose whether your symptoms are caused by the influenza viruses. This test detects the presence of viral genetic material or antigens in respiratory samples, confirming an active flu infection. Accurate diagnosis enables healthcare providers to recommend appropriate treatment and helps in controlling the spread of the virus, especially during flu outbreaks.
