If you’re experiencing ongoing digestive problems, skin issues, headaches or unexplained chronic symptoms, food sensitivities could be contributing. The FIT 176 Test measures delayed immune reactions to 176 foods and additives while also assessing key markers of gut barrier health to help identify foods that may be driving inflammation and support a more personalised nutrition plan.
Please note: This test can only measure your immune response to foods you consume. Foods that have already been eliminated from your diet will not return results.

£456.00
Food sensitivities can develop over time and may contribute to symptoms that are difficult to link to a specific food. Unlike immediate food allergies, delayed immune reactions can take hours or even days to appear, making them challenging to identify without testing.
The FIT 176 Test uses patented multi-pathway technology to assess both IgG antibodies and immune complexes, providing a broader assessment of delayed food sensitivities than IgG testing alone. Alongside this, the Gut Barrier Panel provides additional insight into intestinal barrier health, helping build a more complete picture of factors that may be contributing to ongoing inflammation and digestive symptoms.
The results can help identify foods to consider during a structured elimination diet and support more personalised nutrition strategies based on your individual immune response.
Suitable for adults and children aged 3 years and over who are willing to complete a finger-prick blood collection.

All at-home test kits include clear instructions for sample collection and return, along with necessary packaging. Some tests require you to return the sample on specific days or immediately after collection. Most kits include pre-paid return labels, but some may require you to arrange a prepaid courier collection.

Your kit will come with full instructions and some include video guides. We can support with queries and we encourage you to contact us using the link below before collecting your sample to ensure it can be effectively analysed.
We offer functional testing with and without practitioner interpretation. You can filter tests by consultation on the Functional Testing page. Certain tests, especially those involving clinically significant biomarkers, are only available with interpretation, and some require interpretation by an Integrative Medicine Doctor. We’ll ensure you’re seen by the right practitioner when your results are in. You can purchase a consultation later if you choose standalone testing, but we offer preferential rates for booking upfront.
We provide functional testing to help you make informed health decisions but do not offer medical advice, diagnosis, or treatment. Results are interpreted through a nutritional, lifestyle, and functional medicine perspective, and it is your responsibility to seek further evaluation, diagnosis or treatment from your primary healthcare provider.
Your digital results report will include indicators of how your specific results differ or align with ‘optimal’ ranges in functional medicine. Some reports include an element of written interpretation. If you’ve purchased a consultation we’ll explain your results and interpret them from a nutritional, lifestyle and functional medicine perspective. We may offer suggestions about how Integrative or Functional Medicine can help and can refer you for full consultation or Integrative Health Assessment with a relevant practitioner if desired. If your test includes a clinically significant biomarker and your result is abnormal, we’ll direct you to consult your primary healthcare provider. If you haven’t purchased a consultation and you’re concerned about your results, you’ll be able to opt-in at this stage.
