About this test

This service uses data you already hold from a 23andMe test to generate what Stride describes as 5 reports on your methylation profile. No new sample is collected, so there is nothing to post to a lab and no lab turnaround to wait for.

Stride does not publish how many genes or markers this specific analysis covers, so its clinical depth cannot be properly assessed, which is reflected in a low clinical depth score. There are no other tests in our data directly comparable to it, so no price or depth comparison can be made.

It scores well for collection convenience since no sample is needed at all, and reasonably for clarity given Stride states what the reports cover and how quickly they are produced, though not the underlying genes. It sits in the middle for results and follow-up: a consultation is included, but results are not doctor-reviewed and the report format is not described.

Who is it for?

This is aimed at people who have already tested with 23andMe and want a light, low-cost methylation read from that existing data rather than a new sample. If you have not tested before, or want to know exactly which genes are covered, Stride's own cheek-swab Core DNA & Methylation Test publishes its full 19-gene list for £109.85.

How it works

You upload your existing 23andMe raw data rather than providing a new sample; no physical sample type is needed. Because there is no lab processing step, results are effectively available immediately. A one-to-one consultation is included, though Stride does not describe how the reports are presented, and results are not reviewed by a doctor.

Pros & cons

Pros

No new sample needed if you already hold 23andMe data.
Results are effectively immediate with no lab wait.
Includes a one-to-one consultation with a Stride expert.
Straightforward for anyone already holding 23andMe data, no swab or post needed.

Cons

Stride does not state how many genes or biomarkers this analysis covers.
Results are not reviewed by a doctor.
No comparable tests in our data to check whether the price is good value.

Our editorial score

Compare Health Test Score Basic methylation read from existing 23andMe data

Editorial confidence: 8.0/10

The Core DNA Link turns your existing 23andMe raw data into a basic methylation profile report for £51.35, with no new sample needed and results returned immediately. Stride describes it as 5 reports focused on methylation, and does not state how many genes or markers are analysed, so its depth is hard to judge, and there are no comparable tests in the data to check value.

Score breakdown

Clarity and documentation 6.0/10

The listing publishes a detailed description, a stated turnaround, clear collection options; it does not state the biomarkers measured, the sample type, what the report looks like.
Clinical depth 3.5/10

The provider does not state how many biomarkers are measured, so depth cannot be assessed.
Collection convenience 8.0/10

A finger-prick sample you take at home; results in around 0 days, well ahead of the genetic dna norm of 14.
Results and follow-up 6.0/10

A one-to-one consultation is included in the price, though results are not doctor-reviewed; the provider does not describe the report format.
Trust signals 7.5/10

Trustpilot 4.7 from 148 reviews; accredited lab (UKAS accredited labs); trading 22+ years.
Value for money 6.0/10

£51.35; no comparable tests to benchmark against yet.
