Food Allergy Test

Allergy panel test is done in suspected allergies due to certain vegetarian and non-vegetarian food ingredients commonly used for cooking for determining the exact source causing it (allergen). Since it is a food related allergy, it commonly causes gastro-intestinal symptoms like diarrhoea, but may even lead to other skin related or respiratory symptoms like: Itching, running nose, sneezing, coughing, shortness of breath, hives etc. Certain severe cases may also lead to anaphylactic shock. Based on these results further specific testing is recommended. 

Allergy panel test measures the IgE mediated response to 22 common vegetarian and non-vegetarian food ingredients used for cooking. Total IgE levels are also measured. Further tests to a specific allergen will help in further diagnosis.

Allergy panel test requires a blood sample post exposure to the allergens. A tourniquet (elastic) band is placed tightly on the upper arm. The patient is then asked to make a fist. This helps in the build-up of blood filling the veins. The skin is disinfected before needle insertion and the blood sample is collected in vacutainer. 

Positive result to an allergen indicates that the person is allergic to it. Increased allergen-specific IgE levels further confirms that. Very often the test may be positive for more than one allergen as well. The further treatment course is decided based on the results. Based on the symptom, age, environmental allergens, and region wise allergens further testing may be required for specific diagnosis. Negative result may require other tests for differential diagnosis.

A positive reaction to an allergy-vegetarian+ non-vegetarian panel test means that the patient is sensitive to it. IgE levels that are specific to allergens are higher. It supports this. Quite frequently, more than one allergy may test positive.

Based on the outcomes, the course of additional treatment is chosen. Additional testing may be necessary for a precise diagnosis. This depends on various factors. These include symptoms, age, environmental allergens, and region-specific allergens.

If a test is negative, other tests may be needed for a differential diagnosis.
