Food intolerance blood tests are a type of test that measures the levels of IgG antibodies in your blood. IgG antibodies are proteins that your body produces in response to foreign substances, such as food.

Food intolerance is different from a food allergy. A food allergy is a more serious condition that can cause a life-threatening reaction. Symptoms of a food allergy can come on very quickly and may include:

• Swelling of the face, lips, tongue, and throat

• Difficulty breathing

• Wheezing

• Skin rash, hives, or itching

• Vomiting and diarrhoea

• Dizziness or fainting
