The immune system protects the body against the development of infections caused by bacteria, viruses, fungi and parasites. An allergy is an immune response or reaction to foreign substances called allergens. Allergies are common.

A food allergy is an immune system response that occurs when the immune system fails to recognize food ingredients. These food ingredients are then treated as foreign substances. Eventually the body defensive reaction becomes chronic and could cause health problems.

Immediate reaction food allergies or Type I food allergies affect 1 to 2% of the population and could be quite harmful.

Delayed reaction food allergies or Type III food allergies affect approximately 40% of the population. These allergies can lead to chronic diseases over time.

The main concern with Type III food allergies is that they can often be overlooked because health problems usually appear 8 to 72 hours after certain foods had been ingested.

Here is where our tests can make a difference. With the help of these tests, the physician can find out precisely what causes the patient’s hypersensitivities.
