Chlamydia Pneumoniae (Swab)

Chlamydophila pneumoniae (C. pneumoniae) (swab), throat culture, pneumonia testing

If your healthcare provider suspects you have C. pneumoniae, they may do a swab test of your nose or throat to test for it. C. pneumoniae is just 1 of many types of bacteria that can cause pneumonia. 

You may need this test because you have a bacterial pneumonia, such as C. pneumoniae. This can be potentially life-threatening if not treated. Symptoms may look like a common cold at first. You may have chest congestion, runny nose, and sore throat. But these symptoms can get worse over time. If the infection isn't treated, you may even end up in the hospital. The C. pneumoniae bacteria can't be found by looking through a microscope, so your healthcare provider needs a culture to find out exactly which bacteria you have. This means lab technicians grow and identify the specific bacteria from your sample so your provider can prescribe the right treatment.

Blood tests are sometimes used to identify C. pneumoniae. If your healthcare provider isn't sure of the cause of your infection, you may be tested for other bacteria, too. 

Test results may vary depending on your age, gender, health history, and other things. Your test results may be different depending on the lab used. They may not mean you have a problem. Ask your healthcare provider what your test results mean for you.

The best result of a culture is to find no trace of bacteria. If the culture grows bacteria, then technicians can figure out which types of bacteria are there. The best treatment can then be prescribed. 

Your healthcare provider can take a sputum (phlegm) sample. Or your provider can rub a cotton swab in the back of your throat or nose to collect a sample for culture. The swab is taken to the lab, where the culture is grown to find out what germ is causing your illness.

This test poses no known risks. 

Other bacteria or germs found in your mouth and throat can cause problems in getting an accurate culture from a throat swab. It can also take a while to get back your test results. It often takes 1 to 3 weeks. For this reason, other tests, including blood tests, are often done to check for the cause of pneumonia. This way treatment can be started more quickly. But a blood test is not as accurate as a culture.

No preparation is needed for the test. Be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illegal drugs you may use.
