How to Choose the Right DNA Test

With the multitude of DNA testing companies available, it’s important to carefully choose the right DNA test to suit your specific genealogical goals. Here’s a step-by-step guide to help you make an informed decision and our recommendations on which tests to start with.

1. Set Your Goals:

Before choosing a DNA test, consider what you hope to achieve. Are you mainly interested in finding living relatives, uncovering your ethnic origins, or confirming existing genealogical research? Your objectives will help guide you toward the most suitable test.

2. Research Different Testing Companies:

Explore various DNA testing companies and compare their offerings. Look at factors such as the size of their databases, the range of geographic regions covered, and the depth of genealogical information provided.

3. Understand Types of DNA Tests:

Different DNA tests offer distinct insights. Autosomal DNA tests are ideal for finding relatives across all of your ancestral lines, while Y-DNA and mitochondrial DNA tests specifically trace your direct paternal and maternal lines, respectively.

4. Consider Testing Coverage:

Think about the geographic regions and populations covered by each testing company. If you have a specific interest in a particular region or population, opt for a test that comprehensively includes it.

5. Assess Additional Features:

Some testing companies offer supplementary tools such as chromosome browsers, family tree integration, and the ability to download raw DNA data. Consider these extras when making your decision and learn the tricks to saving money on genealogy and DNA testing.

7. Budget Considerations:

Consider budget for DNA test including shipping, processing, and features. Results can require unexpected and extensive research, discouraging some test-takers. Hiring a professional genealogist can help you reach your goals and is the most cost effective route for people who can’t or do not want to do the research themselves.
