Specimens
should be collected on three consecutive days. These
should be expectorated early in the day before eating,
drinking or cleaning teeth. Specimens contaminated with
food particles are not helpful to the assessment. Send
the specimens daily. Do not save until all three are
collected.
Sputum
should not be sent on the 12 days following bronchoscopy.
If a patient suspected of lung cancer is fit for
bronchoscopy, then it is unnecessary to send sputum for
cytology. |
