  2. Extraction & Isolation: In a laboratory, scientists extract and isolate the DNA from the sample to prepare it for analysis.
  3. Sequencing: Advanced techniques like Next Generation Sequencing (NGS) are employed to read the sequence of nucleotides—the basic building blocks of DNA.
  4. Analysis: Scientists focus on specific genes associated with known disease-causing mutations to identify any irregularities.
  5. Interpretation & Reporting: The findings are compiled into a detailed report, explaining potential health implications based on observed genetic changes.

Important Note: Genomic testing should always be conducted under expert supervision to avoid misinterpretations that could lead to incorrect medical assumptions.

In addition to its medical uses, raw DNA data is invaluable in genealogical research. It helps uncover ancestral origins and trace familial connections, sometimes revealing distant relatives or unknown branches of a family tree.

The process involves:

  1. Collecting: DNA is collected via saliva swabs or blood samples, as in genomic testing.
  2. Analyzing: Specific genetic markers tied to different populations are analyzed using Y-DNA, mtDNA, or Autosomal DNA testing methods.
  3. Comparing: The genetic markers are compared against databases to identify matches or similar genetic profiles, indicating shared ancestry.
  4. Reporting: The results provide an outline of familial relationships and ethnic origins, often presented as percentages.

Caution: Genealogical results reflect probabilities rather than certainties. Outcomes may vary depending on the database’s size and diversity, influencing the accuracy of relationships and ancestral origins.
