Genetic Coeliac Disease Home Test

A saliva-based DNA test that checks whether you carry the HLA-DQ genetic variant associated with coeliac disease risk, for people wanting to understand their genetic predisposition rather than diagnose current symptoms.

About this test

The Genetic Coeliac Disease Home Test analyses a saliva sample for the HLA-DQ genetic marker associated with an increased likelihood of coeliac disease. Carrying this variant does not mean you have coeliac disease, and not carrying it does not rule it out; the test identifies a genetic risk factor rather than diagnosing the condition, and anyone with ongoing digestive symptoms should speak to a GP.

With a single biomarker, this places in the lower-middle range for clinical depth among the gut health tests we track, since depth here reflects the number of markers assessed rather than the value of any one marker. Its price sits almost exactly at the £108 median for the 29 similarly sized gut health tests in our data, so it is neither notably cheap nor expensive for a test of this scope.

The listing scores well for clarity and documentation, publishing a detailed description, the marker tested, a stated turnaround and clear collection details, though it does not describe what the report looks like. Results and follow-up scores low because this test is not reviewed by a doctor as standard, while trust signals remain high, reflecting Randox Health's Trustpilot rating of 4.6 from 29,705 reviews, its UKAS ISO 15189 accredited lab and CQC registration.

Who is it for?

This may suit you if you have a family history of coeliac disease and want to understand your genetic risk before deciding whether to pursue further testing with a GP, or if you want to consider genetics as part of investigating symptoms alongside medical advice. It is a narrow, single-marker test rather than a broad gut health panel.

There are no directly comparable coeliac genetic tests in our data to weigh this against on price or depth. If you are experiencing ongoing digestive symptoms, a GP can arrange clinically appropriate testing and follow-up, which this home test does not include.

How it works

You provide a saliva sample at home using the kit provided and post it to the lab, where it is analysed for the HLA-DQ genetic marker. Results are provided within 1 to 2 weeks of the sample arriving at the lab and are not reviewed by a doctor as standard.

Pros & cons

Pros

  • Simple saliva collection at home, no blood sample required.
  • Priced in line with the £108 median for similarly sized gut health tests.
  • Listing clearly states the single marker tested and the turnaround time.

Cons

  • Tests a single genetic marker rather than a broad gut health panel.
  • Results are not reviewed by a doctor before you see them.
  • A positive or negative result needs interpreting with a GP, which is not included.

Our editorial score

Compare Health Test Score Coeliac genetic risk test priced at the category median
Editorial confidence: 9.0/10

This saliva test looks for the HLA-DQ gene variant linked to coeliac disease risk, rather than testing for the condition itself. At £108 it is priced right at the median for similarly sized gut health tests we track, and results take between 1 and 2 weeks. It is not reviewed by a doctor as standard, so a positive result needs following up with a GP.

Score breakdown

  • Clarity and documentation 9.0/10

    The listing publishes a detailed description, the full biomarker list, a stated turnaround, clear collection options, the sample type; it does not state what the report looks like.

  • Clinical depth 6.4/10

    1 biomarkers, placing it in the 32nd percentile of gut health tests we track.

  • Collection convenience 7.0/10

    A saliva sample you take at home, no needle; results in around 14 days, slower than similar tests.

  • Results and follow-up 3.0/10

    Results are not doctor-reviewed and no consultation is included; the provider does not describe the report format.

  • Trust signals 9.0/10

    Trustpilot 4.6 from 29,705 reviews; accredited lab (UKAS ISO 15189 (Randox Clinical Laboratory Services, lab 9329)); CQC registered.

  • Value for money 6.5/10

    £108.00 against a median of £108.00 for the 29 similarly sized gut health tests we track (-0%).
