Respiratory Pathogen Detection by Nucleic Acid Amplification (Bronchial Lavage/Alveolar Lavage Probe)

How the Test Works

A healthcare provider will insert a thin tube into your airway to collect fluid from your lungs. This fluid is then sent to the lab for analysis. The lab uses a specialized probe to detect genetic material from potential pathogens, including common respiratory viruses and bacteria.

What to Expect Before the Test

You may experience mild discomfort or coughing during the procedure, but it usually takes only a few minutes. You might be asked to stay still while the fluid is collected. Follow any specific instructions your doctor gives you, such as avoiding certain medications or fasting.

What to Expect After the Test

Most people feel fine immediately after the procedure. You may have some mild soreness or discomfort in your throat, but this should pass quickly. Avoid strenuous activity for a short time afterward to allow your body to recover.

Common Causes and Symptoms

Pneumonia can be caused by viruses, bacteria, or fungi. Common symptoms include fever, cough with phlegm, chest pain, difficulty breathing, and fatigue. If you have persistent symptoms like these, especially if you’re at higher risk (e.g., elderly, immunocompromised), this test can help identify the cause.
