Frequently Asked Questions about Sputum Culture and Sensitivity (Aerobic)

Q. How is sputum sample collected?

The sputum sample is collected by asking the patient to cough up. The sample which is coughed up is expelled into a sterile cup provided by the laboratory. To collect the sputum sample, deep coughing is required. The patient is informed that mucus/phlegm is to be collected from the lungs, not the saliva. In case, a patient is not able to produce a sputum sample, it can be induced by guiding the patient to inhale a sterile saline or glycerine aerosol for several minutes. Doing this will loosen phlegm in the lungs. Apart from this, inhalation of steam or a hot shower can also aid in loosening the phlegm.

Q. What preparations are required to be done by the patient before collection of the sputum sample?

The patient is asked to brush their teeth before collecting the sample. Also, the patient is asked to avoid intake of food for at least 1-2 hours before the collection of the sample.
