Genomic DNA from Blood: Probe-Based Detection for Specific Pathogen or Mutation Status

What This Test Measures

The test looks for the presence of specific DNA sequences in your blood. These sequences may be linked to known pathogens (such as viruses or bacteria) or genetic variations that could indicate susceptibility to certain diseases. The probe-based method detects these sequences with high sensitivity.

How the Test Works

Your blood sample is processed to extract DNA. Special probes designed to match the target sequences (pathogens or mutations) bind to these DNA fragments if present. Detection methods (like fluorescence or colorimetric changes) confirm the presence or absence of these sequences.

Why It’s Done

This test may be used for screening, monitoring, or confirmation in situations like infectious disease diagnosis (e.g., certain viral infections), genetic carrier testing, or research-related applications where specific DNA markers are relevant.

Common Uses

Common uses include detecting exposure to specific pathogens (e.g., some viruses or bacteria), assessing genetic predispositions, or confirming suspected infections where traditional tests may not be conclusive.
