The advice in the NICE guideline covers:
- Children and young people up to their 19th birthday who have symptoms or signs that could suggest food allergy.
- Children and young people who are at greater risk of developing a food allergy. For example, they may already have another condition linked with allergies such as asthma, atopic eczema (an allergy-related type of eczema that tends to run in families) or allergic rhinitis (a type of allergy that includes hay fever). Alternatively, they may have a parent, brother or sister with a food allergy or allergy-related condition.
It does not specifically look at:
- Children and young people who have a reaction to a food that is not caused by the immune system (for example, an intolerance to lactose, the main sugar found in dairy products).
