What does Smear for Malignant Cells, Sputum measure?
The Smear for Malignant Cells, Sputum test detects the presence of malignant or abnormal cells in sputum samples. The sputum is collected from a patient and then treated with certain dyes that highlight cell structures, allowing healthcare experts to identify and study atypical or cancerous cells under a microscope. The test primarily identifies lung cancer cells and also detects malignant cells from other respiratory cancers.
A positive result means that the sputum contains abnormal or malignant cells, with a strong possibility of lung cancer or other malignancy of the respiratory system. However, a negative result does not entirely exclude the possibility of cancer, especially in early phases or in cases when cancer cells may not be in the sputum during testing. Further diagnostic procedures, such as imaging tests or a biopsy, may be required to confirm a diagnosis.
