Allergy - Spices Panel

Spice allergy test is done in suspected allergies due to spices 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. 

Spice allergy test measures the IgE mediated response to 7 commonly used spices for cooking. Total IgE levels are also measured. Further tests to a specific allergen will help in further diagnosis.

Spice allergy 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.

The following symptoms are noticed in a spice allergy:

• Diarrhea
• Hives
• Anaphylaxis
• Upset stomach
• Bloating
• Nausea
• Swollen lips
• Shortness of breath

The cost of the spice allergy test in India varies depending on the city. The test costs between ?5,600 and ?8,200 on average.

The treatment for a spice allergy is the same as that for a food allergy. In the case of a severe reaction, injectable epinephrine and antihistamines can significantly alleviate immediate symptoms. Contact dermatitis induced by spices can be treated with topical corticosteroids. However, the best treatment for spice allergy is to avoid contact with or exposure to the allergen(s).

A spice allergy can be easily diagnosed with blood tests and patch tests. If the results come back positive, it is best to avoid the allergens.

Skin prick testing, also known as puncture or scratch testing, can be done to detect the presence of allergic antibodies in case of contact with certain spices.

Celery, garlic, cinnamon, sesame, turmeric, onion and mustard are the most allergens when it comes to spice allergies; mustard allergy is the most common spice allergy. Black pepper and vanilla have also been linked to allergic reactions.

The treatment for a spice allergy is determined based on the type and severity of the symptoms. Oral antihistamines can relieve mild symptoms by suppressing histamine activity. Histamine is a substance that the immune system produces, and this is what causes allergic symptoms.
