Mycoplasma culture, antigen capture-enzyme immunoassay, Ag-EIA
This test looks at sputum, or the mucus from your lower airways. It finds out whether you have a lung infection caused by Mycoplasma pneumoniae, organisms that can cause bronchitis and pneumonia. Mycoplasma are very small and are similar to bacteria. They are unique because they don't have cell walls.
Most people affected by Mycoplasma are younger than 40. Many are between 5 and 20 years old. Mycoplasma pneumonia is sometimes called "walking pneumonia" because people with this illness may not be sick enough to stay in bed or see a doctor. If you have Mycoplasma pneumonia, you can easily infect others who come in close contact with you.
Sometimes a sputum culture test is done, but Mycoplasma don't grow well in a culture. The more common sputum test is called indirect enzyme immunoassay.
You may need this test if your doctor suspects that you have Mycoplasma pneumonia. The most common symptom is a dry, hacking cough. Other symptoms are typical of other respiratory infections:
You may also have a chest X-ray to diagnose pneumonia. If you are in the hospital, you may have your blood oxygen level measured. You may have polymerase chain reaction, or PCR, and DNA testing on throat swabs to help diagnose a Mycoplasma infection. You may also have blood tests, including cold agglutinins and specific antibody tests.
Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your health care provider.
Normal results are negative, meaning you don't have Mycoplasma.
This test requires a sample of your sputum. To collect the sample, you will need to cough deeply into a sterile container. Rinse your mouth with water before providing a sputum sample. Your health care provider may have to suction a sample from your respiratory tract with a thin, flexible tube called a bronchoscope.
Your throat may feel sore after providing a mucus or sputum sample.
Taking antibiotics could reduce the amount of bacteria present. The timing of your test can also affect your results.
Don't eat for one to two hours before providing a sample. Tell your doctor if you have been taking antibiotics.
