Respiratory Pathogen Panel, Culture and Sensitivity (from respiratory specimen)

What This Test Measures

The test involves growing and examining microorganisms from your respiratory secretions (e.g., sputum, nasal swab, or throat swab). It detects the presence of pathogens (e.g., bacteria, viruses, or fungi) and assesses their sensitivity to antibiotics.

How the Test Works

A sample of your respiratory fluid is collected and placed on a growth medium. Over days to weeks, any pathogens present will grow, and lab technicians analyze them. If bacteria are found, they test how they react to different antibiotics to help your doctor choose the best treatment.

When You Might Need This Test

You may need this test if you have symptoms like coughing, fever, difficulty breathing, or persistent sinus congestion that could indicate an infection. Doctors also use it to monitor chronic respiratory conditions or after surgery.

Preparation and Sample Collection

No special preparation is usually needed, but you may be asked to avoid certain medications (like antibiotics) for a few days before testing. The sample is collected by swabbing your throat, nasal passages, or sputum production (if applicable).
