What This Test Measures
This test detects genetic material (nucleic acids) from viruses that can cause respiratory infections, including influenza A and B, parainfluenza, adenovirus, RSV (respiratory syncytial virus), and other flu-like viruses. The method amplifies small amounts of viral genetic material to detect them in your respiratory secretions.
Why It’s Done
Your healthcare provider may order this test if you have symptoms like cough, fever, sore throat, or shortness of breath, especially if you’ve been exposed to respiratory illnesses. It helps determine if a viral infection is the cause and guides appropriate care, such as antiviral medications or isolation recommendations.
Sample Collection
A healthcare provider will collect a sample from your nose or throat using a swab. The swab is then sent to the lab for testing. This is usually done in a clinical setting like a doctor’s office or urgent care.
Test Process
The lab uses a technique called nucleic acid amplification to detect viral genetic material. This involves extracting genetic material from the sample and using enzymes to make many copies of the viral DNA or RNA, which can then be identified. Results are typically available within 24–48 hours.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test helps confirm a viral respiratory infection, which can guide treatment decisions. For example, antiviral medications may be more effective if given early in the course of a viral illness. It also supports public health efforts by identifying outbreaks and informing isolation or vaccination recommendations.
