Allergy - Fruit Panel

Fruit allergy test is done in suspected allergies due to certain fruits for determining the exact fruit source causing it (allergen).

The fruit allergy test measures the IgE-mediated response to 8 different fruits.

1. Apple (Malus X Domestica / Safarchand)
2. Banana (Musa Spp. / Kela)
3. Pear (Pyrus Communis)
4. Peach (Prunus persica)
5. Papaya (Carica papaya)
6. Kiwi Fruit (Actinidia Deliciosa)
7. Mango (Mangifera Indica)
8. Pineapple (Ananas Comosus / Ananas)

Total IgE levels are also measured.

A blood sample after exposure to the allergens is required for the test. The area from where blood will be drawn will be sterilised. Then you will be asked to make a fist with your hand so that your veins are easier to find and measure. Finally, to collect the blood sample in a vacutainer, a tourniquet will be wrapped around your upper arm tightly. This will help in the build-up of blood filling your veins, which will make it easier to collect the sample. This may feel like a prick and slight tenderness may remain at the site of injection for a short while.

A positive result to a particular allergen indicates that the person is allergic to that fruit. Increased allergen-specific IgE levels further confirm 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.
Negative results may require other tests for differential diagnosis.

There are no specific preparations required for the test. However, it is recommended that you consult with your healthcare provider before taking the test, as they may have specific instructions or recommendations based on your individual medical history and current health status.

There isn't a concept of normal level in a fruit allergy panel test. The test results typically reveal the presence or absence of specific antibodies (usually IgE) against various fruits. These antibodies indicate sensitization, which suggests a potential allergic reaction, but not necessarily the severity. Here's a breakdown of how the results are usually interpreted:

• Values below 0.35: This indicates unlikely sensitization to the fruit.
• Values between 0.35-0.69: This is a doubtful significance zone, and further investigation might be recommended.
• Values between 0.70-3.49: There's a possibility of allergy, but confirmation tests might be needed.
• Values above 3.50: Higher values progressively indicate a greater chance of allergy, with values above 17.50 suggesting a very high likelihood.

If you are experiencing some of the following symptoms after consuming fresh fruit, you should schedule an Allergy - Fruit Panel test:

• running nose
• sneezing
• coughing
• itching or swelling of the tongue, lips, or throat
• diarrhoea, stomach cramps, or vomiting

The best thing to do if you are allergic to a particular fruit is to avoid it as much as possible. You could also take anti-allergic medication to neutralise the effect of the agent if you have had it by accident. Seek immediate emergency care if severe symptoms occur.

Anaphylaxis is an allergic reaction that can happen very quickly, and it can lead to several dangerous symptoms including a rapid heart rate, difficulty breathing, a skin rash, vomiting, and nausea. If you or someone you know is having any type of reaction where the airways close up, seek medical help immediately!
