A file and an interpretation have different jobs
Some testing companies let you download genotype data: the DNA letters recorded from your sample. That file is different from the explanatory report supplied by the testing service. Interpreting the data yourself can be difficult, and using another service introduces a new set of privacy decisions. MedlinePlus explains raw genotype data and third-party interpretation.
Keep the original download and its accompanying documentation together. The provider, test version and export date are useful context when a laboratory or interpretation service assesses the file.
Ask what the test actually covered
Different consumer tests may examine different genetic variants. Their results can therefore differ even when they discuss the same condition. The FDA’s guide to direct-to-consumer testing explains why intended use and test limitations matter.
Before comparing two reports, ask whether they used the same measurements and answered the same question. A longer report is not evidence that more relevant information was measured.
A useful distinction
“The file contains no entry for this position” describes the file. It does not establish what a properly validated test of that position would find.
Make an informed sharing decision
Once you download a file, the original service’s protections no longer govern your own copy. Before sharing with another provider, investigate its credibility, interpretation method and privacy arrangements. The National Library of Medicine recommends reviewing these questions.
- What is the intended use of the analysis?
- Which formats and test versions can be assessed?
- Who will have access to the file?
- What are the retention and deletion arrangements?
- How are uncertain results and professional follow-up handled?
