Nucleic Acid Detection in Biological Specimens by Probe-Based Assay

What This Test Measures

The test uses a molecular probe to identify specific sequences of DNA or RNA in your sample. It detects the presence of these sequences, which can indicate infections (e.g., viruses), genetic mutations, or other molecular abnormalities. The probe binds only to its complementary genetic sequence, allowing for highly sensitive detection.

How the Test Works

Your sample is processed to extract nucleic acids. A labeled probe is added that matches the target genetic sequence. If the sequence is present, the probe binds, and detection methods (such as fluorescence or signal amplification) confirm its presence. This method is highly specific and can detect even small amounts of genetic material.

Common Uses

This test is often used for diagnosing infections (e.g., viral, bacterial), screening for genetic disorders, monitoring cancer progression, or confirming genetic testing results. It may also be used in research or specialized clinical settings where precise nucleic acid detection is required.

Sample Collection and Preparation

The test typically requires a biological specimen such as blood, saliva, urine, or other fluids, depending on the clinical indication. Your healthcare provider will guide you on how to collect the sample correctly. The lab processes the sample to isolate nucleic acids before testing.
