What if My DNA Test is Wrong?
DNA tests, while highly accurate, aren't infallible. Several factors can influence results, leading to potential inaccuracies. Understanding these possibilities is crucial for interpreting your results effectively.
Several factors can contribute to inaccurate DNA test results:
- Sample Contamination: Improper sample collection or contamination can lead to inaccurate results. Following instructions precisely is key. Eating before a test, for example, might affect results, though usually a retest is offered if insufficient DNA is collected. [Source: Reddit - I ate before my DNA test...]

What to Do if You Suspect an Inaccurate Result
If you suspect your DNA test results are incorrect, consider the following steps:
- Review the Report Carefully: Examine the report for any discrepancies, inconsistencies, or potential errors.
- Contact the Testing Lab: Reach out to the laboratory that conducted the test. They can clarify ambiguities and explain the procedures. They may also offer a retest.
- Seek a Second Opinion: Consider obtaining a second DNA test from a different, reputable laboratory, using a new sample. This independent verification can help confirm or refute the initial results. [Source: Quora - My child looks exactly like...]
