Type of test Sputum
Normal findings
Normal epithelial cells
Test explanation and related physiology
Tumors in the pulmonary system frequently slough cells into the sputum. When the sputum is gathered, the cells are examined. If the cytologic test result is positive, malignant cells are seen, indicating a lung tumor. If only normal epithelial cells are seen, either no malignancy exists or any existing tumor is not shedding cells. Therefore a positive test result indicates malignancy; a negative test result means nothing.
Bronchoscopy and percutaneous lung biopsy have supplanted the need for sputum cytology to a large degree. Now its greatest use is in patients who have an abnormal chest x-ray result, productive cough, and nothing visible on bronchoscopy.
Procedure and patient care
Before
* Explain the procedure for sputum collection to the patient.
* Remind the patient that sputum must be coughed up from the lungs and that saliva is not sputum.
• Give the patient a sterile sputum container on the night before so that the morning specimen may be obtained on arising.
During
• Sputum specimens are collected as described in the previous study.
• Usually collect sputum on three separate occasions.
After
* Instruct the patient to notify the nurse as soon as the sputum is collected.
• Label the specimen, and send it to the laboratory as soon as possible.
