# A genetic report’s date tells you which explanation you received

You saved a genetic report several years ago, then find a different explanation online. Before replacing the report’s conclusion in your notes, record the dates and versions of both. Researchers can learn more about a finding, and laboratories can change their analysis methods. A later date alone does not prove that someone has reviewed your case.

Your reader question is: “Has the testing team reanalysed my data, or am I looking at a newer public reference?” That distinction helps you ask for an explanation while preserving the original record.

## Keep several dates separate

NCBI’s [ClinVar identifier documentation](https://www.ncbi.nlm.nih.gov/clinvar/docs/identifiers/) explains that records carry accession versions. Some updates change a classification; a submitter can also change a submission date without changing other data. A version increment therefore needs its own explanation.

Imagine two fictional report headers. The first says “issued June 2021, analysis version 2”. The second says “issued September 2026, analysis version 4”. You cannot tell from those headers whether the laboratory changed the measured data, examined additional genes or revised the written explanation. Ask for a change note.

The fictional headers identify no patient or laboratory. Their purpose is to distinguish report issue date, analysis version and evidence date. Keep those as separate fields if the testing team supplies them. “Updated in 2026” compresses information that may answer different questions.

## A public record may default to its current version

The [ClinVar search guide](https://www.ncbi.nlm.nih.gov/clinvar/docs/help/) explains that searching an aggregate accession opens the current record, while specifying an accession and version can retrieve a previous one. Someone reading the same link years later may therefore see a different version.

That database behaviour does not mean a laboratory issued a new personal report. Save the source access date and version if you cite a public record in a question. Ask the testing team to explain relevance rather than copying an internet classification into the original report.

Preserve both documents when a provider issues an update. A simple index can say which report supersedes another and who explained the change. Keep identifying details private; a public discussion does not need the complete report.

## Reanalysis needs a defined scope

NHS England’s [whole-exome sequencing explainer](https://www.genomicseducation.hee.nhs.uk/genotes/knowledge-hub/whole-exome-sequencing/) describes the possibility of returning to stored data as researchers identify new causal genes. It also explains that a virtual panel may limit which genes the team analyses. Having sequence data for many genes does not establish that the original analysis assessed them all.

For your question, distinguish looking again at existing data from collecting a new sample. Ask which information the team would revisit and what technical limits remain. More recent knowledge cannot fill a region that the original test failed to measure.

Avoid assuming an automatic review schedule. The NHS explainer discusses developing reanalysis policies; your testing service needs to describe the policy that applies to your result. Ask whether a request needs a clinician and whether any cost or consent requirement applies, without presuming a free update.

## Ask for a contact and a change explanation

NHS England’s [results-communication framework](https://www.genomicseducation.hee.nhs.uk/competency-frameworks/communicating-germline-genomic-results-a-competency-framework/) includes explaining uncertainty, follow-up and possible future changes. It also identifies laboratory colleagues who can assist with requests for reanalysis. This is a professional framework, not a promise that a particular service monitors every report.

A useful message says, “I have the original report dated this month and year. Please explain whether a newer report exists and what your reanalysis policy covers.” Ask the service how to keep your contact details current through its private channel.

If you receive a reply, note who sent it and which document they referred to. You can preserve their explanation as a dated note instead of editing the older report’s text, making a later comparison easier to follow.

Your next step is to save a report index with issue date, analysis version and the testing team’s contact. You can use [DomDNA’s educational quiz](https://domdna.com/quiz) for general lifestyle topics. It does not reanalyse genomes, update laboratory reports or monitor personal classifications.
