How the Test is Performed
A sputum sample is needed. You will be asked to cough deeply and spit any phlegm that comes up from your lungs into a special container. The sample is sent to a lab. There, it is placed in a special dish (culture). It is then watched to see if bacteria or other disease-causing germs grow.
