How Do Doctors Confirm It's the Flu?
Published: Sep 08, 2023
Diagnosing influenza accurately is crucial for effective treatment. Learn about the tests used to confirm a flu diagnosis.
Diagnostic Tests for Influenza
Rapid influenza diagnostic tests (RIDTs) are commonly used to detect flu viruses in respiratory specimens. These tests provide results in minutes, although their sensitivity can vary.
Molecular Diagnostic Tests
Molecular tests like polymerase chain reaction (PCR) are more accurate than RIDTs. They detect the genetic material of the virus and are often used in hospitals for confirmation.
When Is Testing Necessary?
Testing is particularly important for high-risk patients or those with severe symptoms. Early detection allows for timely antiviral treatment and reduces the risk of complications.
