Turnaround Time

Test Preparation

• Preparing for your test

  Your body only makes IgG antibodies to foods it has recently eaten, so your results depend on what’s been in your diet. If you’ve recently cut out a food because you thought it was causing symptoms, think about reintroducing it in normal amounts for at least 21 days before you test. Otherwise your body may not have produced enough antibodies to it for it to show up. A food you’ve been avoiding could then appear green even if it would otherwise show a raised level.

• Don’t reintroduce a food

  If it makes you feel unwell. If you avoid it on medical advice, for example gluten because of coeliac disease. If you’ve been told by a healthcare professional not to eat it In these cases, keep avoiding the food and bear in mind that its result is likely to be low. If you’re unsure, speak to your GP before reintroducing anything.

• Don’t eat a heavy meal in the 4 hours before testing

  If you collect your sample later in the day, avoid heavy or fatty food for at least 4 hours beforehand. A light snack is fine. Many people find it easiest to collect their sample in the morning before breakfast or after a light one.

• Drink plenty of water

  Being well hydrated helps your blood flow more easily, so collecting your sample is quicker. Drink a glass or two of water in the hour before you test.

• Warm up before you start

  Warm hands give a much better blood flow. Run your hands under warm water for a few minutes, shake them, and let your arm hang down by your side before you prick your finger.

• Medication

  Keep taking any prescribed medication as normal. Some medicines that act on the immune system, such as steroids or immunosuppressants, can alter antibody levels.

Symptom Check

• Bloating

  Feeling swollen, tight or uncomfortably full after meals is one of the most common reasons people look at their diet. Some notice it more after particular foods, such as wheat, dairy or certain vegetables.

• Digestive Discomfort

  Wind, cramping or an unsettled stomach that keeps coming back can leave you wondering what you’ve eaten. Many people want to know whether the foods they eat every day play a part.

• Headaches

  Some people notice headaches seem to follow certain meals, foods or drinks. Because reactions aren’t always immediate, the link can be hard to spot on your own.

• Tiredness

  Feeling sluggish or drained after eating, even when you’ve slept well, is something many people put down to their diet. Knowing how your body responds to everyday foods can help you look at the bigger picture.

• Brain Fog

  Struggling to focus or feeling mentally slow after meals is a common reason people want to understand their diet better.

• Skin Flare-ups

  Some people notice itchy, red or irritated skin seems to flare after eating certain foods. It can be hard to see a pattern when the reaction isn’t immediate.
  
  Symptoms can have many causes. If yours are severe, persistent or getting worse, speak to your GP. If you react within minutes of eating, for example with swelling, hives or difficulty breathing, seek medical help, as this may be an allergy. This test does not diagnose any condition.

Result Report

• Your results report: 286 foods tested

  Your report shows your IgG antibody levels to 286 foods, all from one small finger-prick sample. Your report will be sent to your registered email address as a PDF.
  
  Overview of your IgG profile
  The report opens with a one-page summary of all 13 food groups, from Milk & Egg and Cereals to Spices and Novel Foods. Each group shows a colour rating based on the highest IgG level measured in that group. You can see at a glance where your body has responded most.
  
  Food-by-food results
  Every food is listed within its group with your measured IgG level in µg/ml and a traffic-light rating:
  
  🔴🔴🔴 Highly elevated: 20 µg/ml and above
  🟡🟡 Intermediate: 10–19.99 µg/ml
  🟢 Low: 0–9.99 µg/ml
  
  You get an actual measured value for each food, not just a colour. So you can see how close a food is to the next level and compare foods within the same group.
