Collecting sputum from children, especially infants and younger children, can be challenging. Methods include:
Spontaneous Expectoration: Older children can be asked to cough deeply and expel sputum into a sterile container. Induced Sputum: Involves inhaling a saline solution to induce coughing, often used when spontaneous expectoration is not possible. Nasopharyngeal Aspiration: A catheter is used to suction mucus from the nasal passages, commonly used in infants.
