About this test

The panel looks at 29 genetic markers grouped into three areas: athletic performance (including muscle composition, injury risk and recovery), diet and nutrition (including deficiency risks for vitamins and minerals such as vitamin D, B12 and calcium, plus lactose and gluten sensitivity variants), and broader health and wellbeing (including genetic risk indicators for obesity, type 2 diabetes and high cholesterol, along with caffeine metabolism and sleep). These are inherited genetic variants rather than current blood levels, so they indicate predisposition rather than your present state of health.

Among the genetic and DNA tests we track of a similar size, this sits in the upper range for clinical depth, with 29 markers placing it in the 76th percentile. On price it is towards the higher end too, at £199 against a median of £162.25 for similarly sized genetic tests, so you are paying somewhat more than typical for this level of coverage.

The clinical depth and documentation scores are both strong, since Randox publishes the full list of genes covered along with the sample type and turnaround. The main drags on the overall score are price, for the reason above, and results and follow-up, since results are not reviewed by a doctor as standard and you interpret the genetic report yourself.

Who is it for?

This suits you if you want a broad, at-home genetic snapshot across fitness, nutrition and general wellbeing markers, and you are comfortable providing a saliva sample and waiting 4 to 6 weeks for results. It works best as a starting point for lifestyle changes rather than a clinical assessment.

If price is your main concern, be aware this sits above the typical price for similarly sized genetic tests we track, so it is worth checking whether a narrower or cheaper genetic panel would cover what you actually want to know before committing to the full 29-gene kit.

How it works

You provide a saliva sample at home and post it to the lab. Randox states results are returned within 4 to 6 weeks of the sample arriving at the lab. The provider does not state that results are reviewed by a doctor as standard, so you receive your genetic report to interpret yourself or discuss with a healthcare professional.

Pros & cons

Pros

  • Covers 29 genetic markers across fitness, nutrition and general wellbeing in one kit.
  • Simple at-home saliva sample, no blood draw needed.
  • Randox publishes the full list of genes covered and the turnaround time.
  • Includes deficiency-risk markers for several vitamins and minerals, not just diet-related traits.

Cons

  • Priced above the median for similarly sized genetic tests we track (£199 versus £162.25).
  • Turnaround of 4 to 6 weeks is long compared with most blood or saliva tests.
  • No doctor review of your genetic report as standard; you interpret it yourself.

Our editorial score

Compare Health Test Score 29-gene lifestyle DNA kit, priced above the category median
Editorial confidence: 9.0/10

Using a saliva sample rather than blood, this at-home kit analyses 29 genes covering areas such as nutrition-related deficiencies, food intolerance risk, athletic performance and general wellbeing. At £199 it costs more than the median £162.25 we see across similarly sized genetic tests, and results take 4 to 6 weeks to come back. As with Randox's other tests, results are not reviewed by a doctor as standard.

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 9.1/10

    29 biomarkers, placing it in the 76th percentile of genetic dna tests we track.

  • Collection convenience 7.0/10

    A saliva sample you take at home, no needle; results in around 42 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 5.4/10

    £199.00 against a median of £162.25 for the 7 similarly sized genetic dna tests we track (+23%).
