How the Test Works

A small sample of your nasal or throat secretions is collected and tested. Fluorescent antibodies bind to viral particles if present, making them visible under a microscope. This identifies whether a virus is causing an illness.

Common Uses

This test is often used to diagnose infections caused by viruses like influenza, respiratory syncytial virus (RSV), or other respiratory pathogens in adults and children.

Sample Collection

You may need to provide a nasal swab, throat swab, or nasal aspirate. The sample is sent to the lab where it is processed and tested for viral presence.

Preparation

No special preparation is needed. You may have some mild discomfort during sample collection, but it is quick and painless.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
