Do I Have to Declare a 23andMe Result?

You spat in a tube out of curiosity — ancestry, a few health traits, a rainy Sunday — and now a life insurance application is asking about genetic tests and you have frozen. The short version is reassuring. A health report from a consumer DNA test such as 23andMe or AncestryDNA is a predictive genetic result, and under the agreement that governs this in the UK, a signatory life insurer will not ask you for it and will not take it into account. If you have been wondering whether you have to tell a life insurer about a 23andMe result, the honest answer is that you do not have to hand it over, and they are not allowed to demand it.

That holds whoever ran the test. The rule turns on what the result is — a prediction of future risk in someone who has no symptoms — not on where it came from. A result from an NHS genetics clinic and a result from a shop-bought saliva kit are treated the same way. Both are predictive, and both sit behind the same protection. The kit being cheap, mail-order and taken for fun does not weaken that; if anything the protection was written with exactly this kind of test in mind.

There is one line to understand, though, because the whole answer depends on it. If the kit told you something that then sent you to a doctor — and a symptom, a scan or a diagnosis followed — that later medical history is ordinary information and is fully disclosable. The gene result stays private. What happened to your health after it does not.

The short answer: a home kit result is still a predictive result

Insurers divide genetic information into two kinds, and everything follows from which kind you are holding. A predictive test looks for a gene variant in a person who has no symptoms, in order to estimate the chance of a condition developing in future. That is exactly what a consumer health report does when it tells you that you carry a variant linked to a raised or lowered risk of something. You feel well; the kit is guessing at what might come later. That is the definition of predictive, and predictive results are the ones the UK industry has agreed to leave alone.

So a 23andMe or AncestryDNA health report is not a loophole the insurer will close, and it is not information you are quietly getting away with hiding. It is a category the market decided, deliberately and publicly, that it would not use. The application question about genetic tests is not a trap set to catch your saliva kit. It exists mainly so an insurer can identify the one narrow situation, described further down, where a predictive result is still allowed to matter.

What the Code on Genetic Testing and Insurance actually says

The framework is not a law you can be prosecuted under. It is a voluntary agreement between the government and the insurance industry, and the large majority of the UK life market signs up to it. Signatory insurers commit not to ask you to take a predictive genetic test, not to ask whether you have taken one, and not to take the result into account when they price or decide your application. They also commit not to ask for a relative's result. It is worth confirming that the insurer you are applying to is a signatory, because the commitment is what binds them — but in practice the mainstream names are.

The agreement binds member insurers wherever in the United Kingdom you live, so this is one of the few areas where the position really is the same in England, Wales, Scotland and Northern Ireland. What can differ between the nations is the separate law on how an insurer accesses a report from your doctor, which matters if the kit later led to real medical history — but the genetics rule itself does not change at a border.

If you want to read more widely about how a history or a condition is assessed, our guide to getting cover with a history, a condition or a job sets the genetics rules alongside everything else an underwriter weighs.

Predictive versus diagnostic: the line the answer turns on

This is the distinction almost every worried searcher misses, and getting it right is the difference between over-disclosing something protected and under-disclosing something you genuinely must share.

A diagnostic test is taken to explain symptoms you already have, or to confirm a condition a doctor already suspects. If you were unwell, a clinician investigated, and a genetic test was part of pinning down what was wrong, that result is diagnostic. Diagnostic results are ordinary medical information. They are treated like any blood test or scan on your record, and they are disclosable and askable in the normal way.

A predictive test, by contrast, is taken when you are well, to look ahead. The consumer kit almost always sits on the predictive side, because you were not ill when you spat in the tube — you were curious. The moment that changes is not the test itself but what you do with it. If a kit result nudged you into seeing a GP and something was then found, the finding is diagnostic territory. The rule protects the prediction, not the consequences.

It also helps to know what these kits actually report, because it lowers the temperature. A consumer health report typically flags a handful of common variants and expresses them as a modest shift in probability, not a verdict. It is not the same as a full clinical genetic work-up, and it is not diagnosing you with anything. That is precisely why it falls on the predictive side of the line: it is a statistical nudge about a well person's future, which is the category the industry agreed to set aside.

The one exception, and why it rarely reaches you

There is a single situation in which a predictive result can still be asked for. Where you have had a predictive test for Huntington's disease, and you are applying for life cover above a set threshold, a signatory insurer is permitted to ask about that specific result. This is the only predictive result carved out of the general protection.

Source: HM Government and the Association of British Insurers, Code on Genetic Testing and Insurance. The threshold above which a predictive Huntington's disease result may be asked for is £500,000 of life cover.

For almost everyone reading this, the exception simply does not apply. A consumer ancestry or wellness kit does not run a clinical predictive Huntington's test of the kind the carve-out is about, and most applications are for sums below the threshold in any case. If you did have a formal predictive Huntington's result and were applying for a very large policy, that is the one moment to take proper advice from an FCA-authorised broker before you submit, rather than guess.

When the kit sent you to a doctor

Here is where people trip. Say the report flagged a variant, you worried, you booked a GP appointment, and the GP arranged a blood test or a referral. Perhaps nothing came of it; perhaps something did. Either way, the appointments, the investigations and any resulting diagnosis are now part of your medical history. They are not genetic test results in the protected sense. They are the ordinary stuff of a medical record, and they are disclosable.

Answer the health questions on the form about what actually happened to your body — symptoms, tests, diagnoses, treatment — accurately and in full. You are not breaking the genetics protection by doing so, because you are not disclosing the predictive result; you are disclosing the medical events that followed it. Those events may also surface in a consented report from your GP, so an answer that leaves them out is the kind that unravels later. If you want to understand exactly how far that report can go, what your GP can actually tell a life insurer walks through it.

One more timing point worth naming: if a kit result set off investigations that are still running when you apply, a diagnosis that lands in the gap between applying and cover starting is its own situation, covered in a diagnosis that lands between applying and the policy starting. It is not the same as hiding a gene result, and it has its own rules.

A relative's result, and the family-history question that is different

People sometimes assume that if a parent or sibling tested positive for something, they are obliged to declare that relative's genetic result. They are not. A signatory insurer will not ask for, and you do not have to provide, another person's genetic test result. That protection extends to your family, not just to you.

What is not protected — and this catches people out — is the ordinary family-history question. If the form asks whether a parent, brother or sister was diagnosed with a particular condition before a certain age, that is a straightforward question about your family's medical history, and it must be answered honestly. The difference is subtle but real: an insurer cannot ask what a relative's DNA test showed, but it can ask whether a relative actually had heart disease or a cancer, because that is history, not a prediction. Do not confuse the two, and do not narrow the family-history question because a genetic test happens to sit behind it.

If you want a favourable result taken into account

The protection restricts what an insurer may require. It does not gag you. If your kit or a clinical test produced a reassuring result — you do not carry a variant that runs in your family, say — you are free to volunteer it, and an insurer may take a favourable predictive result into account in your favour. This can genuinely help where a strong family history would otherwise weigh on the assessment: the history is askable, so being able to show that you personally do not carry the variant can reframe it. The specific case of a clear result in an affected family is set out in telling an insurer you tested BRCA-negative in a BRCA family.

If an insurer ever does appear to have used a predictive result against you, that is not something you have to accept quietly. There is a defined route to challenge a decision that you believe breached the genetics rules, explained in challenging a genetics decision within ten working days. And if you are simply weighing up whether the kit changes anything before you apply, the cleanest next step is to get life insurance quotes and let an FCA-authorised broker frame the application around your real medical history rather than your DNA report.

Frequently asked questions

Do I have to declare a 23andMe or Ancestry health result?

No. Under the Code on Genetic Testing and Insurance, signatory insurers will not ask for or take account of predictive genetic test results, and that is what a consumer health report is — regardless of where the test was done. The only exception is a predictive Huntington's disease test where the life cover applied for is above £500,000, which a home ancestry kit does not produce.

What if the result led me to see a doctor?

Then the medical consequences are disclosable, even though the genetic result itself is not. Symptoms, investigations, diagnoses and treatment are ordinary medical information. They will be asked about on the health questions, and they may appear in a consented report from your GP. Answer accurately about what happened to your health after the test, while leaving the predictive result out of it.

Can an insurer ask about a relative's test result?

No. Signatory insurers commit not to ask for a relative's genetic test result. Ordinary family-history questions are a separate matter: if the form asks whether a parent or sibling had a particular condition before a certain age, that must be answered honestly, because it is medical history rather than a genetic prediction.
