Flu
What the test is for:
A flu test is a diagnostic tool to identify influenza viruses causing respiratory illnesses. It helps distinguish between the flu and other similar illnesses. Rapid and accurate testing aids healthcare providers in tailoring treatment plans and implementing preventive measures to curb the spread of the virus.
Virus details:
Influenza, or the flu, is a contagious respiratory illness caused by influenza viruses. These viruses can mutate, leading to seasonal outbreaks. The flu is characterized by symptoms such as fever, cough, body aches, and fatigue. Timely testing is crucial for prompt treatment and preventing further transmission.
What it detects:
A flu test detects the presence of influenza viruses in respiratory specimens. By identifying specific viral antigens or genetic material, the test confirms if a person is infected with the flu virus. Rapid and accurate detection enables healthcare professionals to initiate appropriate interventions, reducing the severity and duration of symptoms.

Frequently Asked Questions
There are primarily two types of flu tests:
- Rapid influenza diagnostic tests (RIDTs): These tests provide quick results (usually within 15-30 minutes) but may be less sensitive than molecular tests.
- Molecular tests (such as PCR): These tests detect the genetic material of the influenza virus and are considered highly accurate.
Flu testing is recommended for individuals who present with symptoms of respiratory illness, especially during flu season, which typically occurs in the fall and winter months.
Some molecular tests may have the capability to differentiate between influenza A and B viruses and identify specific strains or subtypes of influenza viruses, such as H1N1 or H3N2.
Molecular tests (such as PCR) are considered highly accurate for detecting influenza viruses when performed correctly. Rapid influenza diagnostic tests (RIDTs) may have variable sensitivity but can provide quick results.
Flu tests specifically detect influenza viruses and are not designed to diagnose other respiratory infections caused by different viruses or bacteria. However, some molecular tests may have the capability to detect multiple respiratory pathogens simultaneously.
