H1N1
Understanding H1N1
What is H1N1?
The H1N1 test is used to detect the genetic material of the H1N1 influenza(flu) virus in the respiratory samples. The test helps doctors diagnose H1N1 flu infections and guide treatment decisions.
H1N1 influenza, commonly called swine flu, is a subtype of the influenza A virus. It is a zoonotic infection (transmitted from animals to humans) that causes viral flu-like symptoms in humans. It is typically transmitted through respiratory droplets via coughing or sneezing by infected individuals.
The signs and symptoms of H1N1 infection vary by age, underlying health conditions, and immune function. However, your doctor may suggest the H1N1 test when you have symptoms such as cough, sore throat, runny nose, nasal congestion, headache, and low-grade fever indicative of flu or a similar respiratory illness. The time from when a person is exposed and infected with flu to when symptoms begin is about 1-4 days but can range for up to 7 days. Therefore, get tested with the H1N1 test as soon as the symptoms appear. Additionally, this test helps confirm whether the symptoms are caused by the H1N1 virus or another influenza virus.
No special preparations are required to get tested with the H1N1 test. However, before sample collection, a duly filled Swine Flu/H1N1 Clinical Information Form (Annexure - CR/04) is mandatory. This form can be provided by the laboratory personnel (phlebotomist) before sample withdrawal. It entails important information about your medical history, diagnosis, and treatment.
Lab test results may vary across different laboratories. Abnormal test results require an expert interpretation; therefore, never try to self-medicate at home based solely on these results, and always consult a doctor for a proper understanding of the test results.
What is H1N1 used for?
The H1N1 test is done:
- To confirm whether an individual has been infected with the H1N1 (swine flu) virus.
- As a part of the viral flu panel, particularly in the flu season.
- When someone experiences symptoms such as fever, chills, sore throat, runny nose, body ache, or cough suggestive of viral infection.
- To help doctors differentiate between the swine flu and other influenza infections.
- To identify H1N1 infection in vulnerable populations, such as young children, older adults, pregnant women, and individuals with underlying health conditions.
- To monitor treatment response against H1N1 Infection.
What does H1N1 measure?
The H1N1 test checks for the presence of the H1N1 virus, also called the swine flu (influenza) virus, and confirms the infection. Influenza or flu is a viral infection that affects your respiratory system. The infection is usually mild and resolves on its own, but the infection can be life-threatening in children under 5 years, adults above 65 years of age, and those with weakened immune systems. Hence, early detection via timely testing becomes crucial.
