Influenza Panel PCR - Influenza A, H1N1, H3N2, Influenza B' Test
Influenza Panel PCR - Influenza A, H1N1, H3N2, Influenza B' Test
Influenza Panel PCR test is a diagnostic assay to detect the presence of the Influenza virus in the patient's respiratory tract. The test uses a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) technique to differentiate between influenza A and B viruses, as well as subtype the influenza A viruses into H1N1 and H3N2 in the sample (usually throat and nasal swabs) collected from patients with sign and symptoms of respiratory viral infection.
Influenza is a contagious respiratory illness caused by different strains of the influenza virus that spreads mainly through the air (large droplets and aerosols from sneezing and coughing) and sometimes by touching virus-contaminated surfaces. When there is an upsurge of respiratory illnesses with symptoms similar to the common cold, the influenza Panel PCR helps doctors speed up treatment efforts and take appropriate infection control measures to prevent the virus from spreading into the community.
What is the Influenza Panel PCR Test Used For?
Your doctor may request an Influenza Panel PCR assay
To diagnose patients suffering from flu from some days
To differentiate between the flu and other viral or bacterial infections
For determining the severity of infection and provide appropriate treatment plan for early patient recovery
To identify the spread of influenza infection into the community
Symptoms of Influenza
People suffering from influenza often show these signs and symptoms
Fever with chills
Recurrent cough with sore throat
Runny or stuffy nose
Muscle and joint pains
Headaches
Tiredness
Vomiting and diarrhea in children
Preparation for Test
Generally, the Influenza Panel PCR (Influenza A&B, H3N2, H1N1) requires no special preparation. But before sample collection, let your doctor know the history of your medical conditions and any allergies you may have.
Interpretation of Test Results
Results of Influenza Panel PCR are interpreted as follows:
Positive result (Abnormal)
This report indicates the presence of active flu-causing viruses (Influenza A or B, H3N2, and H1N1) in the provided sample.
Negative result (Normal)
This report means you don't have an active infection at the time of sample collection, but it does not necessarily rule out the risk of getting infected with the virus after testing.
FAQs
What is the difference between Influenza A and Influenza B?
Both Influenza A and B are strains of the influenza virus cause similar symptoms; however, they differ in severity and transmission. Influenza A spreads more easily and leads to more severe complications than Influenza B.
What to expect during the test?
To do this PCR test, a swab or brush of cells is inserted into the patient's throat and nasal passage to collect the sample.
Who should get the Influenza Panel PCR Test done?
This test is usually advised for individuals with symptoms of sore throat, fever, repeated cough, etc., as well as those who have been in contact with a COVID-positive person or patient with flu.
Are any risks associated with the Influenza Panel PCR (Influenza A&B, H3N2, H1N1)?
Influenza Panel PCR (Influenza A&B, H3N2, H1N1, RSV) is generally safe. However, you may feel slight discomfort during sample collection (nasal and throat swabs), although the odds of serious complications are extremely rare.
How accurate is the Influenza Panel PCR test?
Rapid molecular influenza diagnostic tests can detect influenza virus genetic material in upper respiratory tract samples with high sensitivity (90-95%) and specificity, indicating high accuracy.
