Influenza A
The Influenza A test measures the presence of the influenza A virus in the body, primarily through a sample taken from the nasopharynx. Clinicians typically order this test when a patient exhibits symptoms such as fever, cough, sore throat, and body aches, especially during flu season. The Influenza A test is essential in differentiating influenza from other respiratory infections, helping guide appropriate treatment and management decisions during outbreaks or in at-risk populations.

Clinical Information
Clinical Significance
Abnormal results from the Influenza A test can indicate an active influenza A infection, which may require medical attention, particularly in vulnerable populations. While a positive result may confirm influenza, a negative result doesn't rule out the possibility of other respiratory infections. It’s crucial to remember that only a healthcare provider can interpret your results in the context of your overall health and symptoms.
Reference Ranges
Reference ranges for the Influenza A test indicate whether the virus is detected in your sample. A positive result suggests the presence of the influenza A virus, while a negative result indicates that it was not found. These ranges may vary based on laboratory methods and population factors, so it's important to consult with your healthcare provider for personal interpretation.
Sample Preparation
Before your Influenza A test, there are generally no special preparations required. You do not need to fast or adjust any medications. However, it’s advisable to inform your healthcare provider about any medications you are currently taking. The sample will be collected using a swab from your nasopharynx, and it’s important to follow any specific instructions given by your healthcare provider.
