The specimen must be transported to the laboratory promptly; delays can lead to overgrowth of contaminants or degradation of pathogens. Another significant pitfall is contamination by saliva, which manifests microscopically as high squamous epithelial cell counts.
Ensuring Patient Cooperation for a High-Quality Sputum Sample
Unlike saliva, which originates from the mouth and throat, deep cough sputum contains cells and microbes from the respiratory tract where infections occur. Explaining the purpose—that this sample helps identify the specific germ causing the illness—can motivate the patient to exert the necessary effort for an adequate sample.
Understanding Sputum and Its Diagnostic Value Sputum is the mucus and cellular debris expelled from the lower airways, specifically the bronchi and lungs. Once collected, the container must be labeled immediately with patient identifiers to prevent mix-ups.
Enhancing Patient Cooperation for a High-Quality Sputum Sample
If the sample is deemed unacceptable, it is better to request a repeat collection than to proceed with analysis, as the results would be unreliable and potentially harmful to the patient. For patients who are unable to generate a sample through voluntary effort, such as those who are intubated or have a productive cough, suctioning via a tracheal tube may be employed.
