What Is a Food Intolerance Test and How Can This Bundle Help You?

 

Living with unexplained bloating, persistent fatigue, skin flare-ups, or digestive discomfort can be exhausting — especially when you have no idea what is causing it. The food intolerance test at the heart of the yorktest Food Intolerance & Allergy Bundle is designed to take the guesswork out of your diet. This bundle combines two types of testing in one: an IgG food intolerance screen and an IgE food allergy screen, giving you a broader picture of how your immune system is responding to the foods you eat every day. If you have been struggling with symptoms that seem to flare after meals, this could be the starting point you have been looking for. You might also find it useful to explore our allergy and hay fever range for additional symptom support while you await your results.

The bundle is produced by yorktest, one of the UK's most established names in food sensitivity testing. It is not a medicine, but a laboratory diagnostic service that uses a simple finger-prick blood sample collected at home. The sample is then analysed in a certified laboratory for reactions to a wide range of food and drink ingredients.

 

How Does the yorktest Food Intolerance & Allergy Bundle Work?

 

The science behind this bundle centres on two distinct immune pathways:

  • IgG antibody testing (food intolerance): Your blood is screened for elevated immunoglobulin G (IgG) antibodies against specific food proteins. A raised IgG response to a food is associated with delayed-onset symptoms such as bloating, headaches, and fatigue — though it is worth noting that IgG testing remains a subject of ongoing clinical debate.
  • IgE antibody testing (food allergy): The bundle also screens for immunoglobulin E (IgE) antibodies, which are associated with classic, immediate allergic reactions — including hives, swelling, and in severe cases, anaphylaxis.
  • Laboratory analysis: Your finger-prick sample is sent to a certified laboratory where it is tested against a panel of food antigens.
  • Results report: You receive a detailed, personalised results report, typically within 7 days of the lab receiving your sample, along with access to a nutritional therapist consultation.

 

Who Should Consider Using This Bundle?

 

This bundle is aimed at adults who have been experiencing unexplained, recurring symptoms that they suspect may be linked to their diet. It is particularly relevant if you have already spoken to your GP and ruled out other causes, or if you are looking for a more detailed picture before making dietary changes. It is not a replacement for NHS allergy testing or medical diagnosis.

  • Adults experiencing chronic bloating, wind, or irregular bowel habits
  • People with persistent skin conditions such as eczema or unexplained rashes
  • Those suffering from recurring headaches, brain fog, or unexplained fatigue
  • Individuals who have already tried elimination diets without clear results

 

How Does the yorktest Bundle Compare to Other Food Testing Options?

 

Feature yorktest Food Intolerance & Allergy Bundle NHS GP Allergy Referral
Tests IgG food reactions Yes No (not routinely offered)
Tests IgE food allergies Yes Yes (skin prick or blood test)
Home sample collection Yes – finger-prick No – clinic attendance required
Nutritional therapist support Included Not typically included
Turnaround time ~7 days Weeks to months (waiting list)

 

Is the yorktest Bundle Clinically Validated and How Should It Be Stored?

 

The yorktest laboratory is accredited and uses enzyme-linked immunosorbent assay (ELISA) methodology for IgG testing. It is important to understand that while IgG food sensitivity testing is widely used in private practice, it is not currently recommended as a diagnostic tool by NHS allergy guidelines — the NHS advises that IgG antibodies to food are a normal immune response and do not necessarily indicate intolerance. This bundle is best used as a starting point for dietary investigation, ideally alongside guidance from a qualified dietitian or your GP. If you are managing gut-related symptoms, you may also find our IBS and cramps collection helpful for symptomatic relief in the meantime.

Store the unopened kit at room temperature, away from direct sunlight and moisture. Once you have collected your blood sample, return it to the laboratory as promptly as possible — ideally on the same day — following the instructions included in the kit. Do not refrigerate or freeze the sample card.

This product is a diagnostic test kit, not a medicine. Speak to your doctor or pharmacist before using if you have an underlying medical condition or are taking other medicines.

Specifications of yorktest Food Intolerance & Allergy Bundle

 

What Is the yorktest Food Intolerance & Allergy Bundle and What Is It Used For?

 

The yorktest Food Intolerance & Allergy Bundle is a home-to-laboratory diagnostic kit that screens your blood for two types of immune responses to food: IgG-mediated food intolerances and IgE-mediated food allergies. It is used by adults who want to identify whether specific foods may be contributing to symptoms such as bloating, fatigue, skin problems, headaches, or digestive discomfort. The kit is not a medicine and does not treat any condition — it provides information to help guide dietary decisions, ideally in conjunction with a healthcare professional.

Food intolerance and food allergy are distinct conditions. According to the NHS, a food allergy triggers an immune response that can cause symptoms ranging from mild hives to life-threatening anaphylaxis, while food intolerance tends to produce delayed, less severe symptoms affecting digestion and general wellbeing. This bundle aims to screen for both, giving you a more complete picture.

 

What Do You Need to Know Before Using the yorktest Bundle?

 

Before using this kit, read the following carefully. This test is not suitable for everyone, and there are important limitations to be aware of.

Do not use this kit if:

  • You have a known history of anaphylaxis — seek NHS allergy clinic referral instead
  • You are under 18 years of age
  • You are pregnant or breastfeeding, unless advised by your GP
  • You are currently taking immunosuppressant medications, which may affect antibody levels
  • You have a bleeding disorder or are taking anticoagulant medicines such as warfarin

Important warnings:

  • IgG food sensitivity testing is not endorsed by NHS allergy guidelines as a diagnostic tool for food intolerance
  • A positive IgG result does not confirm a clinical diagnosis of food intolerance
  • Do not eliminate major food groups based solely on test results without dietitian guidance — this can lead to nutritional deficiencies
  • This test does not screen for coeliac disease; if you suspect coeliac disease, speak to your GP for appropriate NHS testing

Potential interactions to be aware of:

  • Immunosuppressant drugs (e.g. corticosteroids, methotrexate) may suppress antibody production and affect results
  • Antihistamines taken regularly may influence IgE results — discuss with your GP before testing
  • Recent dietary changes or elimination diets may reduce IgG reactivity to excluded foods

 

How Should You Use the yorktest Food Intolerance & Allergy Bundle?

 

Using the kit correctly is essential for accurate results. Follow these steps carefully:

  1. Register your kit online using the unique code provided in the box before collecting your sample.
  2. Wash your hands thoroughly with warm water and dry them — this helps improve blood flow to your fingertips.
  3. Use the lancet provided to prick the side of your fingertip (not the pad).
  4. Allow blood to drop onto the collection card, filling the required number of circles as instructed.
  5. Allow the sample card to air-dry completely for at least 30 minutes before sealing.
  6. Place the dried sample card in the biohazard bag and then into the prepaid return envelope.
  7. Post your sample to the yorktest laboratory on the same day, avoiding weekends where possible.
  8. Check your email for notification that your results are ready — typically within 7 days of the lab receiving your sample.
Test Component Age Group Sample Required Turnaround
IgG food intolerance screen Adults 18+ Finger-prick blood sample ~7 days from receipt
IgE food allergy screen Adults 18+ Finger-prick blood sample ~7 days from receipt
Nutritional therapist consultation Adults 18+ N/A – telephone/online Booked after results

 

What Are the Possible Side Effects of Using This Kit?

 

Because this is a diagnostic test kit rather than a medicine, side effects are minimal and relate primarily to the finger-prick blood collection process. That said, it is worth knowing what to expect.

Common side effects (related to finger-prick sampling):

  • Brief, sharp discomfort at the puncture site
  • Minor bruising around the fingertip
  • Small amount of bleeding that resolves quickly with gentle pressure

Less common side effects:

  • Lightheadedness or feeling faint — sit down before collecting your sample if you are prone to this
  • Localised redness or soreness at the puncture site lasting a day or two

If you experience prolonged bleeding, signs of infection at the puncture site, or feel unwell after collecting your sample, contact your GP. It is also worth noting that acting on results — such as eliminating multiple food groups — without professional guidance can cause unintended nutritional consequences. If you are supporting your gut health alongside testing, our vitamins and supplements collection includes products that may help maintain nutritional balance during a dietary review.

 

How Should You Store the yorktest Food Intolerance & Allergy Bundle?

 

  • Store the unopened kit at room temperature (15–25°C), away from direct sunlight and damp conditions
  • Do not refrigerate or freeze any component of the kit
  • Keep out of reach of children
  • Once the blood sample has been collected and dried, return it to the laboratory as soon as possible — ideally the same day
  • Do not post your sample on a Friday or over a bank holiday weekend, as delays may affect sample integrity
  • Check the expiry date on the kit before use — do not use if the kit has expired

You can order the yorktest Food Intolerance & Allergy Bundle directly from Cured Pharmacy online, with delivery to your home address. The kit arrives with everything you need to collect your sample and return it to the laboratory. No GP referral is required to purchase this bundle.

How does the yorktest food intolerance test work in the body?

The test analyses a small finger-prick blood sample for elevated IgG antibodies (associated with delayed food reactions) and IgE antibodies (associated with immediate allergic responses) to a wide range of foods. The sample is processed using ELISA methodology in a certified laboratory. Results indicate which foods your immune system is producing a measurable antibody response to.

How do I use the yorktest Food Intolerance & Allergy Bundle step by step?

Register your kit online using the code in the box, then collect a finger-prick blood sample using the lancet provided and apply it to the collection card. Allow the card to dry for at least 30 minutes, seal it in the prepaid return envelope, and post it to the yorktest laboratory. Results are typically available within 7 days of the lab receiving your sample.

How long does it take to get results from the yorktest bundle?

Results are usually ready within 7 days of the laboratory receiving your sample. You will receive an email notification when your personalised results report is available to view online. Posting your sample early in the week helps avoid weekend delays.

What is the difference between a food intolerance and a food allergy?

A food allergy involves an IgE-mediated immune response that can cause rapid, potentially severe symptoms including hives, swelling, and anaphylaxis, according to the NHS. A food intolerance typically involves a delayed IgG response and causes symptoms such as bloating, fatigue, headaches, and skin issues. The yorktest bundle screens for both types of reaction.

Who is eligible to use the yorktest Food Intolerance & Allergy Bundle?

The bundle is suitable for adults aged 18 and over who are experiencing unexplained symptoms they suspect may be linked to their diet. It is not recommended for people with a history of anaphylaxis, those taking immunosuppressant medicines, or those who are pregnant, without first consulting a GP. Children under 18 should not use this kit without medical supervision.

Is the yorktest food intolerance test accurate and clinically validated?

The yorktest laboratory uses ELISA methodology and holds accreditation for its testing processes. However, it is important to note that IgG food sensitivity testing is not currently endorsed by NHS allergy guidelines as a diagnostic tool — the NHS states that IgG antibodies to food are a normal immune response and do not necessarily confirm intolerance. Results should be interpreted alongside advice from a dietitian or GP.

Can I use the yorktest bundle if I have a history of anaphylaxis?

If you have experienced anaphylaxis or severe allergic reactions in the past, you should consult your GP before using any home testing kit. Severe food allergies require formal clinical management and NHS allergy clinic testing, not a home-based screen. Your GP can refer you to an NHS allergy specialist for appropriate IgE testing.

What foods does the yorktest bundle test for?

The yorktest Food Intolerance & Allergy Bundle screens for reactions to a wide range of common foods and drinks, including dairy, gluten-containing grains, eggs, nuts, soy, and various fruits and vegetables. The full list of foods tested is detailed in the kit documentation and your results report. Contact yorktest directly for the complete panel list before purchasing if this is important to your decision.

What happens after I receive my yorktest results?

Once your results are available, you will receive a detailed personalised report showing your IgG and IgE reactivity levels for each food tested. The bundle includes a consultation with a yorktest nutritional therapist who can help you interpret your results and plan a structured dietary approach. It is advisable to share your results with your GP or a registered dietitian before making significant dietary changes. If gut symptoms are a concern, our IBS and cramps collection may offer additional support.

What are the alternatives to the yorktest Food Intolerance & Allergy Bundle?

Alternatives include GP-referred NHS allergy testing (which covers IgE-mediated allergies but not IgG intolerances), supervised elimination diets guided by a registered dietitian, or other private laboratory food sensitivity panels. The yorktest bundle is distinctive in combining both IgG and IgE screening with a nutritional therapist consultation in a single home-use kit. You can also explore our allergy and hay fever range for symptomatic relief products.

Can I take the yorktest bundle if I am on antihistamines or steroids?

Regular use of antihistamines may influence IgE antibody results, and immunosuppressant medicines such as corticosteroids can suppress antibody production and affect both IgG and IgE readings. It is advisable to speak to your GP or pharmacist before testing if you are taking any of these medicines. Discuss whether a temporary pause in medication is appropriate before collecting your sample.

How long should I follow the dietary changes recommended after my yorktest results?

yorktest typically recommends following a structured elimination and reintroduction programme for a minimum of 8 to 12 weeks, guided by your nutritional therapist consultation. The duration depends on your individual results and how your symptoms respond to dietary changes. Always work with a qualified dietitian or your GP when making significant long-term dietary modifications to avoid nutritional deficiencies.

Does the yorktest bundle test for coeliac disease?

No — the yorktest Food Intolerance & Allergy Bundle does not test for coeliac disease. Coeliac disease is an autoimmune condition diagnosed via specific blood tests (tTG-IgA antibody) and confirmed by intestinal biopsy, which must be arranged through your GP. If you suspect coeliac disease, do not start a gluten-free diet before being tested, as this can affect the accuracy of NHS coeliac tests.

What are the latest research findings on IgG food intolerance testing?

Research on IgG food sensitivity testing remains mixed. While some studies suggest that IgG-guided elimination diets may reduce symptoms in conditions such as IBS, major allergy bodies including the British Society for Allergy and Clinical Immunology (BSACI) do not currently recommend IgG testing as a diagnostic tool for food intolerance. The NHS position is that IgG antibodies to food are a normal immune response and their presence does not confirm intolerance. Speak to your GP for the most up-to-date clinical guidance.

How Should You Use the yorktest Food Intolerance & Allergy Bundle?

Using this kit correctly ensures your sample reaches the laboratory in the best possible condition and that your results are as accurate as possible. Before you begin, make sure you have registered your kit online using the unique code found inside the box — you cannot receive your results without completing this step first.

What Is the Correct Dose of the yorktest Food Intolerance & Allergy Bundle?

This is a single-use diagnostic test kit, not a medicine, so there is no dosage in the traditional sense. Each bundle is designed for one person to use once. The table below summarises the testing components and their intended use.

When Is the Best Time to Use the yorktest Food Intolerance & Allergy Bundle?

Collect your sample in the morning when you are well hydrated and have eaten normally in the days leading up to the test — do not fast or restrict your diet beforehand, as this may affect IgG antibody levels. Avoid collecting your sample if you are unwell, as acute illness can temporarily alter immune markers. Post your sample on a Monday, Tuesday, or Wednesday to ensure it reaches the laboratory before the weekend.

How Long Can You Use the yorktest Food Intolerance & Allergy Bundle For?

This is a one-time diagnostic test. Once you have collected and returned your sample, the kit is complete. If you wish to retest — for example, after completing a dietary elimination programme — you would need to purchase a new kit. yorktest recommends retesting no sooner than 6 months after completing a structured dietary programme, to allow sufficient time for antibody levels to change in response to dietary modifications.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of the yorktest Food Intolerance & Allergy Bundle?

Because this is a diagnostic test kit rather than a medicine, the side effects associated with it relate almost entirely to the finger-prick blood collection process. Most people find the lancet causes only a brief, sharp sensation lasting a second or two.

  • Brief stinging or sharp discomfort at the puncture site
  • Minor bruising around the fingertip
  • Small amount of bleeding that stops quickly with gentle pressure
  • Mild soreness at the puncture site for a day or two

What Are the Less Common Side Effects of the yorktest Food Intolerance & Allergy Bundle?

A small number of people may experience additional reactions, particularly if they are sensitive to blood collection procedures. These are uncommon but worth being aware of before you begin.

  • Lightheadedness or feeling faint — sit down before and during sample collection if you are prone to vasovagal responses
  • Localised redness or swelling at the puncture site lasting more than 48 hours
  • Difficulty obtaining enough blood — warming your hands beforehand can help

What Are the Serious Side Effects of the yorktest Food Intolerance & Allergy Bundle?

Serious side effects from a finger-prick test are extremely rare. However, if you notice signs of infection at the puncture site — such as increasing redness, warmth, swelling, or discharge — contact your GP promptly. People with bleeding disorders or those taking anticoagulant medicines such as warfarin should not use this kit without medical advice, as bleeding may be more difficult to control.

What Should You Do If You Experience Side Effects?

For minor discomfort or bruising at the puncture site, apply gentle pressure with a clean cotton pad until bleeding stops. If you feel faint, lie down with your legs raised and wait until the feeling passes before continuing. Do not attempt to collect your sample alone if you have a history of fainting during blood tests. If you experience prolonged bleeding, signs of infection, or any unexpected reaction, contact your GP or call NHS 111 for advice.

Can the yorktest Bundle Interact With Other Medicines?

This kit does not involve taking any medicine, so direct drug interactions do not apply. However, certain medicines can affect the accuracy of your test results. Immunosuppressant drugs — including long-term oral corticosteroids, methotrexate, and biologics — may suppress antibody production and lead to falsely low IgG or IgE readings. Regular antihistamine use may also influence IgE results. If you are taking any of these medicines, discuss the timing of your test with your GP or pharmacist before proceeding.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
