Respiratory Syncytial Virus (RSV) Nucleic Acid Detection by Probe-Based Assay
This test checks for the presence of respiratory syncytial virus (RSV) genetic material in your respiratory secretions. RSV is a common virus that can cause respiratory infections, especially in infants, older adults, and those with weakened immune systems.

Why This Test Might Be Ordered
Your healthcare provider may recommend this test if you or your child have symptoms like coughing, wheezing, or difficulty breathing, especially during RSV season (typically late fall through spring). It’s also used to diagnose RSV in infants with severe respiratory illness or in high-risk groups.
How the Test Works
The test uses a specialized probe to detect RSV genetic material in your nasal or throat secretions. This is done through a molecular process that identifies the virus’s DNA or RNA, confirming its presence without relying on traditional culture methods.
Sample Collection
A healthcare provider will collect a sample using a swab from your nose or throat. The swab is then sent to the lab for testing. This is a quick and painless procedure, especially for children.
What to Expect After Testing
After collection, the sample is processed in the lab to detect RSV genetic material. Results are typically available within 24 to 48 hours, depending on lab workflows. If RSV is found, your provider will discuss next steps, such as treatment or monitoring.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test helps confirm RSV infection, which can guide treatment decisions. While RSV infections are usually mild, they can be serious in vulnerable populations, such as newborns, young children, or those with chronic lung or heart conditions. Early identification can help manage symptoms and prevent complications.
