Pneumococcal Nucleic Acid Detection in Respiratory Specimen (Qualitative Probe-Based Assay)
This test checks for the presence of genetic material from *Streptococcus pneumoniae* (pneumococcus) bacteria in your respiratory secretions, such as sputum or nasal swabs. It helps identify if you may have an infection caused by this bacterium.
["Quickly determines if pneumococcal bacteria could be the cause of your respiratory symptoms."]

What This Test Measures
The test detects specific genetic sequences unique to *Streptococcus pneumoniae*. These sequences are found in the bacteria’s DNA and are not present in human cells. The probe-based method amplifies and identifies these sequences to confirm infection.
Why It’s Done
Your healthcare provider may order this test if you have symptoms like cough, fever, or difficulty breathing, especially if they suspect pneumonia or another respiratory infection caused by pneumococcus.
How It’s Performed
A sample of your respiratory secretions (e.g., sputum, nasal swab, or throat swab) is collected and sent to the lab. The test uses a molecular probe to detect pneumococcal genetic material directly from the sample.
What to Expect Before or After
No special preparation is needed. If you’re having a nasal or throat swab, you may experience mild discomfort. Results are typically available within 24 hours and can guide further treatment decisions.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions
This test helps confirm a pneumococcal infection quickly, allowing for targeted antibiotic treatment if needed. Early identification can reduce complications and improve recovery.
This test only detects the presence of pneumococcal genetic material, not the full bacterial load or other types of bacteria. It does not measure viral infections.
The specimen must be collected properly (e.g., deep nasal swab or sputum sample) to ensure accurate results. If the sample is contaminated or improperly handled, results may be unreliable.
