What the original test reports.
A genotype chip tests a selected set of positions. Retain the original export as the source record; its coverage and missing calls shape the inference.

A different kind of evidence.
Extend a compatible RAW file with statistically inferred genotypes for suitable research workflows. Keep the distinction between what was measured and what was estimated in view.

Imputed genotypes are estimates. This service is for ancestry research and genealogy, not health or medical decisions.
Understand the difference
Measured and modeled are different.
The value of a denser dataset depends on the analysis you plan to run and the uncertainty you can accept.
What a reference model estimates.
Population haplotype patterns help estimate untyped positions. Confidence varies by marker, input and reference representation. Additional rows do not guarantee a better model or match.
Your deliverablesThree outputs.
Three outputs.
Different next steps.
RAW datasets are delivered in both HG19 (GRCh37) and HG38 (GRCh38), covering chromosomes 1 to 22 and X. Counts vary with the input and processing.
Y-DNA and mtDNA are not imputed. Download and keep your results within the 15-day availability window.
- Full RAW datasetThe expanded dataset retains the imputed output alongside original typed markers, for workflows that can accommodate the larger file.
- Probability-filtered RAW datasetA smaller output retains typed markers and applies max(GP) ≥ 0.995 to imputed SNPs. It provides a different size and confidence trade-off, not a clinical guarantee.
- Imputed VCF archiveOne compressed VCF per chromosome, with genotype and allele probabilities for advanced workflows. Index files are not included; downstream preparation may be required.
From source to output

Independent third-party websites set their own rules for which files they accept. DNA Genics does not operate those websites and is not affiliated with them. They can change their rules at any time. This service is complete when the file is available in your account in the format described for the service. If a third-party website later refuses that file because of its own upload rules, that decision belongs to that website. A missing file, or a file that is not in the format described, is still our responsibility. This notice does not remove rights that Spanish or EU consumer law does not allow us to exclude. GEDmatch and MyTrueAncestry are examples of those independent websites.
Before you order
Questions that matter.
Inference, formats and file handling deserve a clear answer.
Privacy PolicyWhat does imputation add?
It estimates some untyped genotypes using the observed markers and a reference panel. The extra genotypes are predictions, not additional DNA measured by your original test. More rows do not automatically mean a more accurate result.
What will I receive?
The service provides a full RAW dataset, a smaller probability-filtered RAW dataset, and imputed VCF files with genotype and allele probabilities. RAW outputs cover chromosomes 1 to 22 and X in both HG19 and HG38. Output counts depend on the input, reference panel and filtering.
What does the 0.995 filter mean?
The smaller output retains imputed SNPs only when the maximum genotype probability is at least 0.995; typed SNPs are retained. This is a model probability filter, not a guarantee that 99.5 percent of the output is correct.
Which files can be used?
Start with a supported RAW genotype export. The available marker overlap, missing calls, format and representation in the reference panel affect the result. Sequencing files that are not supported RAW exports need appropriate conversion first.
Can another website use the output?
Each independent website controls its accepted formats and upload rules, which can change. Some research tools also need format conversion, suitable references and further preparation. Acceptance and improved results are not guaranteed.
How should I handle the downloads?
Downloads are available for 15 days after delivery, so save your copies promptly and protect them as genetic information. Review the upload information and Privacy Policy for processing, consent and retention before supplying a file.
Can imputed genotypes guide medical decisions?
No. They are statistical estimates for ancestry research, genealogy and suitable academic workflows. They are not a clinical test, medical diagnosis, identity check or proof of a family relationship.
