What Is An Influenza A & B Test?
Influenza A & B virus is responsible for seasonal flu outbreaks. Influenza A is common and causes severe illness while influenza B is milder but can still pose significant health risks to vulnerable populations like elderly, young children and immunocompromised individuals. Influenza A & B test is a diagnostic tool used to detect the presence of virus in the sample.
This test is crucial for confirming flu infections during flu season when the symptoms may overlap other respiratory illness like the common cold or COVID-19. Early diagnosis allows doctors to prescribe antiviral medications that are most effective when administered in 48 hours of symptoms onset. Additionally this test can also help public health officials to track flu outbreak and implement preventive measures to control the spread of the virus. By identifying the virus strain, the test helps in determining the appropriate treatment thus reducing the risk of complications as flu can quickly progress to pneumonia or other respiratory illnesses.
How is the Test Performed?
Sample Collection
This is a swab test and requires a nasopharyngeal swab, nasal swab or throat swab. A healthcare professional will insert a sterile swab into your nostril or throat to collect a sample of respiratory secretions.
Lab Testing
The sample is tested using rapid antigen tests, molecular tests or virus cultures.
Processing Time
Rapid tests provide results in 15-30 minutes while molecular tests may take a few hours.
What are the symptoms that prompt this test?
Symptoms of influenza are mostly the same in adults and children, however the intensity of the symptoms may vary from one individual to another. The most common symptoms are:

This is a qualitative test and does not have any numerical ranges.
A Positive result means there is a presence of influenza A or B virus in the sample provided. While a Negative result means no presence of virus was detected in the sample.
**The above mentioned range is for information purpose only. Normal levels are dependent on a number of factors including age, gender how the test is performed and health condition of patient etc. Result interpretation should be done by a qualified doctor or healthcare professional.**
What Happens if Test Results Show Abnormal Levels?
If test results are positive for Influenza A or B, your doctor may recommend:
- Antiviral Medications may be administered to help reduce symptoms and duration.
- Supportive Care, hydration, rest and over-the-counter medications to relieve symptoms.
- If complications are suspected, additional tests like a chest X-ray or blood tests may be ordered.
- To prevent the spread of the virus, infected individuals may need to stay home and avoid contact with others.
- Symptoms of influenza are uncomfortable but mostly mild. Hospitalization may be required if the symptoms are severe.
