Lower Respiratory Tract Antigen Detection by Probe (Respiratory Pathogen Panel)

What This Test Measures

The test uses a molecular probe to identify antigens from common respiratory pathogens. These pathogens may include viruses like respiratory syncytial virus (RSV), influenza viruses, or bacteria like *Chlamydia pneumoniae*. The probe detects these substances in a sample of your respiratory secretions, collected via a nasal or throat swab.

How the Test Works

The probe-based assay amplifies and detects the presence of these antigens through a sensitive detection method, often part of a nucleic acid amplification test (NAAT) or similar molecular technique. This helps distinguish between viral and bacterial causes of respiratory illness.

Common Uses and When to Request This Test

Your healthcare provider may recommend this test if you have symptoms of a lower respiratory infection, such as persistent cough, wheezing, or difficulty breathing, especially if other tests (like a chest X-ray or viral panel) are inconclusive. It’s often used in outpatient settings or during acute illness to guide treatment decisions.

Sample Collection and Preparation

A healthcare professional will collect a sample from your upper airway (nose or throat) using a swab. The sample is then processed in a lab to extract and analyze the respiratory antigens. No special preparation is needed before the test.
