Nucleic Acid Detection in Serum/Plasma by Probe-Based Assay

What This Test Measures

The test detects specific sequences of nucleic acids (DNA or RNA) using a molecular probe. If your blood contains the target genetic material, the probe will bind to it, confirming a positive result. This method is highly sensitive and can detect very small amounts of genetic material.

How the Test Works

Your blood sample is processed to extract nucleic acids. A probe—small, labeled molecules designed to match a specific genetic sequence—binds to these acids if they are present. Detection methods (such as fluorescence or color change) confirm the presence of the target nucleic acid.

Common Uses

This test may be used for diagnosing infections (e.g., viral infections like COVID-19), detecting genetic disorders, or monitoring conditions where nucleic acids are relevant (e.g., cancer research or research studies).

What to Expect Before the Test

No special preparation is typically needed, but you may be asked to fast or avoid certain medications if directed by your healthcare provider. Bring any relevant medical records or questions about your test.
