Oral Provocation test

Oral Provocation test

Oral provocation tests are conducted when in doubt about a food or drug allergy.

If allergy is already proven, there is no need for this type of test. However it is often conducted in order to clearly establish ABSENCE of an allergy to the suspected allergen.

It will also enable to reintroduce a drug or a food, once we have the near certainty that the patient is not allergic to it.

The test is ingested by the patient (usually in liquid form). Doses of the allergen are increased regularly, under strict medical supervision,  until the concentration is such that presence or absence of tolerance to the allergen is clearly established.
