Pneumococcal Nucleic Acid Detection in Blood by Probe-Based Assay

What This Test Measures

The test analyzes a sample of your blood for genetic fragments from *Streptococcus pneumoniae* (pneumococcus). These fragments are detected using a highly sensitive molecular probe that binds specifically to the bacteria’s DNA. This method is highly accurate for identifying pneumococcal infection, even in early stages.

Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have signs of pneumonia, sepsis, or other serious infections where pneumococcus is a suspected cause. It can also be used in high-risk groups (e.g., elderly, immunocompromised) to monitor for potential infections.

How the Test Works

The blood sample is processed to extract DNA. The molecular probe targets a unique sequence in pneumococcal DNA, allowing the test to detect its presence with high sensitivity. Results are typically available within hours, providing rapid confirmation or exclusion of infection.

Sample Collection and Preparation

A small blood sample is drawn from a vein, usually in your arm. The sample is processed immediately or stored under specific conditions to preserve DNA integrity before testing. No special preparation is needed beyond standard blood draw protocols.
