10-second summary
Genetic testing in Ireland typically costs between €250 and €2,000, depending on the test. Life insurers cannot ask for or use your genetic test results, but they will assess your family history and any ongoing medical investigations. Knowing what to say and when to apply matters.
Editor’s note: This guide was updated in March 2026 to reflect current rules on genetic testing and life insurance in Ireland, including typical costs and how insurers assess risk in practice.
One of the big questions people have is whether genetic testing can affect their life insurance.
Logically, you’d think it would.
If a test shows you’re at higher risk of something like cancer or a hereditary condition, it feels like the insurer should factor that in.
But that’s not how it works.
How much does genetic testing cost in Ireland?
It depends on what you’re testing for.
Private genetic testing in Ireland typically ranges from about €250 at the lower end to €2,000 or more for more detailed testing.
- Basic screening tests: €250–€500
- Targeted tests (for example, breast cancer gene testing): €500–€1,500
- More advanced or full genetic panels: €1,000–€2,000+
Some tests are available through the public system, but access is usually limited and waiting times can be long.
If you want a more detailed overview of how genetic testing works in Ireland, the HSE explains it well here.
Most people looking this up aren’t just curious about the price.
They’re trying to understand their risk.
Does genetic testing affect your life insurance?
No.
Life insurers in Ireland cannot ask for, request, or use the results of genetic tests when assessing your application.
Even if you volunteer the information, they’re not allowed to use it.
That cuts both ways.
- If a test shows you’re at higher risk, they can’t load your premium because of it
- If a test shows you’re at lower risk, they can’t give you a discount either
So your genetic test results sit completely outside the underwriting process.
What insurers can use instead
This is where people get caught out.
Just because genetic test results are off-limits doesn’t mean insurers are in the dark.
They’ll still assess:
- Your family medical history
- Your personal medical history
- Any symptoms you’ve experienced
- Any tests, referrals, or investigations you’re going through
So if your sister had breast cancer, that matters.
If you’re currently being referred for checks, that matters.
If you’re waiting on scans or results, that matters.
They all affect underwriting decisions, so the insurer you apply to can make a big difference.
Do you have to disclose genetic test results?
No.
In fact, you’re specifically told not to disclose them.
But there’s an important distinction:
You don’t disclose the test result…
…but you must disclose the reason you had the test in the first place if it involves symptoms, referrals, or investigations.
That’s the part people miss.
Predictive vs diagnostic tests — what’s the difference?
Not all genetic testing is treated the same way in practice.
- Predictive testing — done to assess future risk (for example, BRCA testing)
- Diagnostic testing — done because you already have symptoms or a doctor is investigating something
If you’ve had predictive testing, the results don’t need to be disclosed, and insurers can’t use them anyway.
But if you’re having tests because of symptoms, referrals, or ongoing investigations, that does need to be disclosed regardless of whether genetics are involved.
Where people get this wrong
This is where applications start to go sideways.
- Assuming genetic testing protects them from underwriting
- Oversharing information that doesn’t need to be disclosed
- Applying while investigations are still ongoing
In reality:
Different insurers assess risk differently.
The order you apply matters.
And once a decision is made, it can follow you.
Being accepted by one insurer doesn’t mean you got the best outcome.
If you’re unsure, it’s far better to get a view from all of the insurers rather than apply blindly.
That’s where we come in.
When should you apply for life insurance?
Timing matters more than people realise.
- Before testing: usually cleanest (but if you know you have an upcoming diagnostic test, the insurers will likely press pause until the results are available)
- After testing: still fine, results won’t be used
- During ongoing investigations — this is where delays and loadings can happen
If there’s one mistake that causes problems, it’s applying while something is still “open”.
That’s what slows everything down.
Can you get mortgage protection after genetic testing?
Yes, and the same rules apply.
Your genetic test results cannot be used by the insurer.
But your overall medical picture still matters, especially if you have had symptoms.
That’s why people run into issues close to drawdown.
It’s rarely the genetic test.
It’s everything around it.
Next steps
If you’ve had genetic testing, or you’re thinking about it, and you’re not sure how it might affect your life insurance application, it’s worth getting that right before you apply.
Because once you apply, you don’t get to rewind it.
