JDTesting provides a comprehensive home-to-laboratory service for all tests and programs. Your kit is mailed to you along with a prepaid return envelope for sending back your sample. After testing, your results are delivered to you by mail.

Yes, absolutely. All samples are processed in a UK-based, ISO-accredited laboratory. This ensures that your test results meet the highest scientific standards of accuracy and reliability.

Since May 2022, but our experience has been for over 13 years in total.

Our tests are not offered through the NHS. However, certain health insurance companies may cover some of the costs. If you have health insurance, your provider can confirm whether a specific test is included in your coverage.

Once your sample reaches our lab, the typical turnaround time for results is 5–7 working days. We’ll notify you via email as soon as your report is ready.

Allergy and intolerance are frequently mistaken for one another or believed to be the same, but they are actually quite different. An allergy is an immediate and potentially severe or life-threatening reaction to a food or drink, often occurring from a young age and involving the antibody IgE. Intolerance, on the other hand, can develop later in life and typically has delayed symptoms, making it harder to identify the offending food or drink. Testing can help identify trigger foods more quickly and accurately.

Proper nutrition during pregnancy and breastfeeding is essential for the health of both mother and child. To minimize potential risks to either, JDTesting protocol recommends against offering tests, advice, or lifestyle recommendations during these periods. Additionally, there is not enough data to establish reference ranges for testing in pregnant and breastfeeding women.

If you are using steroids or immunosuppressants, your results may be impacted, as these medications can reduce antibody production. However, antihistamines, antibiotics, and other medications will not affect the test outcomes.

We are unable to recommend reintroducing a food that you know causes adverse reactions. If you haven't consumed a certain food for over six weeks, it may not be detected by our test. However, for example, if you’re avoiding gluten but occasionally have a small amount of wheat flour once a week, this could still be identified by our testing if you are intolerant. We suggest maintaining your usual diet before taking the test.
