Sputum is a thick fluid that is produced in the lungs and the airways leading to the lungs.
Testing sputum is the best way to test for active pulmonary tuberculosis disease.
It may take up to 8 weeks to get the final results from a sputum test.
You have been asked to produce three early morning sputum (phlegm) samples. To help you collect them, we have given you three specimen jars and a plastic bag. The jars are labelled with your name and numbered "1", "2", and "3", for three consecutive days. Please be careful not to touch the inside of the jar at any time.
Note: It is essential you supply sputum / phlegm from the lungs not saliva (fluid from the mouth) for this test.
If you have a problem producing sputum turn on the water taps in the bathroom until the room is filled with steam. (Please take care to avoid hot water overflow and scalding). Close the door and sit in the steamy room for five to ten minutes, then try again. Alternatively, you could try a warm shower or bath before trying to cough up the sputum. Breathing deeply while pressing firmly on the sides of your chest, followed by a deep cough can also help to bring up sputum.
Note: It may take up to 3 working days to get preliminary results, and 6 - 8 weeks to obtain the final culture results. The Clinic nurses will notify you of any abnormalities.
Contact your chest clinic if you have any questions about the collection of these specimens.
