Pneumococcal Nucleic Acid Detection (Serum/Plasma Probe)

What This Test Measures

The test uses a molecular probe to detect genetic fragments of *Streptococcus pneumoniae* (pneumococcus), a common cause of pneumonia, meningitis, or bloodstream infections. It’s not a traditional antibody test but identifies the bacteria’s DNA directly, which can occur even before symptoms develop.

Why It’s Done

Your healthcare provider may order this test if you have signs of infection (e.g., fever, confusion, or respiratory symptoms) or if you’re at high risk for pneumococcal infections (e.g., young children, elderly adults, or those with weakened immune systems).

Sample Collection

A blood sample is drawn from a vein, typically in your arm. The blood is processed to separate plasma (the liquid part) for testing. This is a quick, non-invasive procedure.

What to Expect

You may feel slight discomfort at the injection site, but the procedure takes only a few minutes. No special preparation is needed, though you might want to drink water afterward to help reduce any bruising.
