About this test

This test uses a cheek swab to screen six genetic markers linked to lactose intolerance, gluten intolerance, caffeine sensitivity, alcohol metabolism, sodium sensitivity, and a genetic link between caffeine and anxiety. Rather than testing a food reaction directly, it looks at whether you carry gene variants associated with each of these areas, alongside personalised nutrition recommendations.

Against a median price of £84 for similarly sized genetic tests we track, this £54 test is 36% cheaper. Its six markers place it in the lower range for depth among the wider set of genetic and DNA tests we track, which often screen more genetic areas.

The value for money score is strong given how far below the comparable median this sits, but the clinical depth score is more modest, reflecting a smaller marker count than many genetic tests. Results and follow-up scores low, because results are not reviewed by a doctor, and collection convenience is held back by the roughly 28-day turnaround for a swab-based test.

Who is it for?

This suits anyone who wants a lower-cost first look at a genetic tendency behind digestive symptoms such as bloating or discomfort around specific foods, and who is comfortable waiting around 28 days for results without a doctor review. It does not test a food reaction directly, so it will not tell you whether you currently have an intolerance, only whether you carry a related genetic variant.

How it works

You take a cheek swab sample at home and post it to MyHealthChecked's UK laboratory. Results are ready within 28 days and come with personalised nutrition recommendations; the listing does not include a doctor review as standard.

Pros & cons

Pros

  • Screens six genetic areas from lactose to sodium sensitivity in one swab
  • 36% cheaper than the £84 median for similarly sized genetic tests we track
  • Comes with personalised nutrition recommendations

Cons

  • Not reviewed by a doctor
  • Results take around 28 days, far slower than MyHealthChecked's blood tests
  • Tests a genetic tendency, not whether you currently have an intolerance

Our editorial score
