Influenza B Virus

The Influenza B Virus test measures the presence of genetic material (RNA) of the Influenza B virus, responsible for causing flu-like symptoms to more severe respiratory illnesses, particularly in high risk individuals (such as children or people with weakened immune systems). The test requires a nasopharyngeal swab sample and uses Real-time PCR technology to identify the Influenza B infection. A positive result indicates an active Influenza B infection, while a negative result shows no virus was detected at the time of testing. This test also helps differentiate Influenza B from other respiratory viruses with similar symptoms, ensuring an accurate diagnosis and guiding the appropriate treatment to reduce complications.
