Throat cultures are diagnostic tests to identify infectious agents in the throat. Doctors use them to prescribe the right medication and prevent the spread of infections. Patients should avoid using mouthwash before the test and inform the doctor if they are taking antibiotics. A quick test can identify streptococcal bacteria, while a laboratory culture can detect other organisms. Candida albicans is a common fungus identified with throat cultures. Throat infections can be painful and dangerous, especially for people with compromised immune systems.
A throat culture is a diagnostic test that is performed to determine whether a patient has an infectious agent in their throat and, if so, which one is responsible for the infection. Throat cultures are done if a doctor suspects someone carries a disease or if a doctor wants to learn more about the cause of someone’s sore throat. Collecting a sample for culture is a quick and painless process, although some patients find it inconvenient.
Doctors recommend that their patients refrain from using an antiseptic mouthwash before a throat culture, as this can interfere with the results. If the patient is taking antibiotics, it is important to inform the doctor. To collect a sample for culture, doctors quickly swab the throat. Many patients experience a gag reflex or desire to close their mouth while the swab is being applied; it can help to focus on a distant object in the room as a distraction while the doctor swabs.
If a doctor suspects a strep throat might be caused by a strep infection, they can use a quick test, which takes about 10 minutes. In this case, the swab is dipped into the rapid test kit and quickly checks for the presence of streptococcal bacteria. If the throat culture is positive, drugs can be given immediately. If it is negative, a culture will need to be done in the laboratory, growing the swab to see if any bacteria, fungi or other organisms are present.
Throat cultures can be very helpful when a doctor is preparing a prescription. With a culture, a doctor can decide which drug would be most effective for treatment, ensuring that the patient is getting the right drug from the start. Cultures can also be useful in identifying carriers, who can then be treated to eliminate the infectious agent so they stop passing it on to other people.
Another common infectious agent identified with a throat culture is Candida albicans, which can colonize the mouth and throat. Infection with this fungus is sometimes known as “oral thrush” and is often characterized by white streaks in the mouth that can be identified even without a culture.
A throat infection can be painful and irritating. It can also be dangerous, as there is a chance that the infection will spread. This makes getting treatment important, especially if a patient will be around people with compromised immune systems, because the patient could pass the infection on to someone who isn’t equipped to deal with it. An individual with a compromised immune system who develops a sore throat should get a throat culture quickly to determine the cause so that treatment can be started.
