Cough Sputum Culture and Sensitivity (with Endotracheal Suction Catheter Specimen)

Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like persistent cough, fever, difficulty breathing, or if you’re receiving mechanical ventilation. It’s particularly useful for patients with weakened immune systems, chronic lung diseases, or those who’ve been exposed to hospital-acquired infections.

How the Sample Is Collected

A healthcare professional will collect a sample directly from your endotracheal suction catheter during a procedure. This sample contains mucus, bacteria, or other pathogens from your airways. The sample is then sent to a lab for culture and sensitivity testing.

What the Test Results Mean

Results typically show whether bacteria, fungi, or other microbes are present and which antibiotics (if any) could effectively treat the infection. Some tests also indicate if the organism is resistant to common medications.

Common Conditions Monitored

This test is often used to diagnose or monitor infections in patients with conditions like chronic obstructive pulmonary disease (COPD), cystic fibrosis, severe pneumonia, or those on long-term ventilator support.
