Classic allergies relate to cases where the adverse reaction is very quick and can often be violent and severe. It occurs usually within the hour.  Symptoms can often include swelling of the lips, throat or other areas of the body, skin rashes, breathing difficulties, runny nose, and digestive symptoms such as vomiting, pain or diarrhoea.

Classical food allergies are quite rare, and affect a very small minority. They are, however quite dangerous, e.g. peanuts are known to have the potential to kill individuals, unless adrenaline is injected quickly to stop the allergic reaction.

Food intolerances or sensitivities affect a great number of people, you can grow in and out of them. The symptoms caused by food intolerances rarely occur immediately after eating the offending food, they can occur after several minutes, hours or even days later which makes detecting the offending foods very difficult for the individual. This is where the test helps by pin pointing the  offending foods.
