Pneumococcal Group DNA (Qualitative) in Nasopharyngeal Aspirate or Swab by Nucleic Acid Amplification Test
This test checks for the presence of genetic material from *Streptococcus pneumoniae* (pneumococcus), a common cause of pneumonia, ear infections, and other serious illnesses in children and adults.
["Helps identify if you may have an infection caused by pneumococcus before symptoms appear."]

Why This Test Is Done
Your healthcare provider may order this test if you have symptoms like fever, cough, or trouble breathing, or if you’re at higher risk for pneumococcal infections (e.g., young children, elderly adults, or those with weakened immune systems). It can also be used to screen for colonization in people who may have been exposed to pneumococcus.
How the Test Works
A sample of your nasal secretions (nasopharyngeal aspirate or swab) is collected and tested for genetic material from pneumococcus using a specialized lab technique that detects DNA without measuring its quantity.
Sample Collection
A healthcare provider will gently insert a small swab into your nose to collect fluid from the back of your nasal passages. This is usually quick and painless, though it may cause a slight tickle or mild discomfort.
Test Results Interpretation
A positive result means genetic material from pneumococcus was found, suggesting possible infection. A negative result means no genetic material was detected, but this does not rule out infection entirely—other causes may be present.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
Short name
Pneumococcal DNA Screen
Frequently asked questions
Can help confirm a diagnosis of pneumococcal infection early, allowing for prompt treatment with antibiotics to prevent complications or spread of the bacteria.
If you have symptoms like severe coughing or difficulty breathing, additional tests (e.g., blood cultures or chest X-rays) may be needed to guide treatment.
The test results may take 24–48 hours to return, depending on lab processing times.
