Massive Database vs. Microscopic Detail
These two kits represent opposite philosophies. AncestryDNA goes wide — the largest consumer DNA database on the market, built to maximize your odds of finding relatives and connecting to historical records. Living DNA goes deep — a smaller database, but regional detail within the British Isles that few competitors even attempt to match.
Neither approach is wrong. They’re just optimized for different goals, and figuring out which one actually fits you is what this comparison is for.
Who Should Look Elsewhere
If your ancestry sits well outside the UK, Ireland, Western Europe, or North America, both of these kits will likely disappoint you to some degree — Living DNA especially, since its whole value proposition is regional depth for a specific part of the world.
If you’re chasing health insights specifically, neither kit is designed for that as its primary function.
Otherwise, here’s the real comparison.
Database Size: No Contest
AncestryDNA has the largest database of any consumer DNA testing company, by a wide margin. Living DNA’s database is considerably smaller in comparison.
This matters most for relative matching. More people in the database means dramatically higher odds of finding second cousins, distant relatives, and unexpected family connections. If discovering new relatives is a major part of why you’re testing, this single factor probably decides the comparison on its own.
Regional Detail: Living DNA’s Entire Reason to Exist
Here’s where the comparison flips completely. AncestryDNA’s ethnicity breakdown is solid and reasonably detailed for its size, but it generally reports at the level of larger regions — “England & Northwestern Europe,” for instance — rather than granular sub-regions.
Living DNA, by contrast, can break the British Isles down into dozens of distinct sub-regions. If your family history runs through a specific part of England, Scotland, Ireland, or Wales, and you want detail specific enough to potentially point toward a particular historical county, Living DNA does something AncestryDNA simply doesn’t attempt at the same resolution.
What Each Test Actually Analyzes
AncestryDNA focuses on autosomal DNA — the standard approach most ancestry kits use, covering your broad ethnic makeup and relative matches.
Living DNA goes further, testing autosomal, Y-DNA, and mitochondrial DNA together in a single kit. This gives you insight into your direct paternal and maternal lines specifically, not just your overall ethnic composition — a meaningful difference if you’re trying to trace a specific line of descent rather than get a general picture.
Historical Records: AncestryDNA’s Strongest Card
If your genealogy research plans include digging through census records, immigration documents, and military records, AncestryDNA is significantly ahead here. Its records integration is one of the most extensive available, and DNA matches connect directly into a documented family tree with automatically surfacing research hints.
Living DNA doesn’t offer a comparable records archive. It’s built specifically as an ancestry testing tool, not a broader genealogy research platform, so if paper-trail research matters to you, this is a real gap.
Turnaround Time
AncestryDNA typically returns results in three to four weeks. Living DNA’s stated window is six to eight weeks, sometimes stretching to ten or twelve during busier periods. This is one of the more significant practical differences between the two — if you’re not particularly patient, or you’re testing for a specific occasion, the wait time alone might settle the decision.
Price
Both kits sit in a similar mid-range price bracket for the base test, and both run periodic sales. AncestryDNA’s overall cost tends to climb higher if you add the historical records subscription, which Living DNA doesn’t have an equivalent to. Living DNA’s optional wellbeing add-on is a smaller expense by comparison if you choose to add it.
So, Which One Should You Choose?
Choose AncestryDNA if:
- Finding as many potential relatives as possible matters most to you
- You want to do serious historical research using original documents
- Your ancestry is broadly Western European, North American, or otherwise well-represented in a large database
Choose Living DNA if:
- Your family history is specifically rooted in the UK or Ireland
- You want granular regional detail, not just a broad ethnicity percentage
- You’re interested in direct paternal/maternal line analysis (Y-DNA and mitochondrial DNA)
- You can comfortably wait out a longer turnaround time
Testing With Both
Because these two serve different purposes — broad discovery versus deep regional analysis — some people genuinely benefit from testing with both rather than picking one. It’s a bigger investment, but if you have known UK ancestry and also want the widest possible net for finding relatives, the combination covers more ground than either kit alone.
Comparing Against the Rest of the Field

Frequently Asked Questions
Is Living DNA worth it if I already tested with AncestryDNA? It can be, particularly if your ancestry includes UK or Irish roots and you want more granular regional detail, or if you’re interested in Y-DNA and mitochondrial line analysis that AncestryDNA doesn’t provide.
Why does Living DNA take so much longer than AncestryDNA? Living DNA’s more extensive analysis — combining autosomal, Y-DNA, and mitochondrial testing — requires more lab processing time than AncestryDNA’s standard autosomal-only approach.
Which kit has better historical records? AncestryDNA, by a significant margin. Its records archive is one of the most extensive in the industry, while Living DNA doesn’t offer a comparable historical document database.
The Bottom Line
If you want the biggest possible pool of potential relatives and strong historical research tools, AncestryDNA is the stronger overall choice. If your roots are specifically British or Irish and you want detail most competitors can’t match, Living DNA earns its place despite the smaller database and longer wait. The right pick depends less on which company is “better” and more on which type of answer you’re actually looking for.
