Nucleic Acid Detection in Plasma/Serum (PCR-Based Probe)

What This Test Measures

The test uses a specialized probe to identify fragments of genetic material (nucleic acids) from a targeted pathogen. These fragments are often released into your blood during an active infection. The probe binds to these fragments if they are present, allowing for detection via molecular techniques.

How the Test Works

This is a polymerase chain reaction (PCR)-based assay performed on plasma or serum. The sample is processed to amplify and detect the pathogen’s genetic material, which may not be detectable by other methods alone.

Why It’s Used

This test is particularly useful for diagnosing infections where traditional blood tests may be inconclusive, such as certain viral, bacterial, or parasitic infections that cause subtle or early-stage symptoms.

Common Uses

Common indications include suspected infections like certain viruses (e.g., some respiratory or bloodstream pathogens), chronic infections where symptoms are mild, or in cases where other diagnostic tests are negative or inconclusive.
