Allergic reaction against nuts like Brazil nuts is often similar to reaction that occur after severe food poisoning. Since these reactions are severe and can escalate to anaphylaxis immediately, it is necessary to take the Brazil nut allergy test.
The severity of the Brazil nut allergy depends on the following factors:
Age of the person
Amount of nuts consumed
Location of the person
Type of nut
Other allergies or disorders
Since the chances of overcoming nut allergies are very low, it is safer to go for a nut allergy test and check for the specific allergies in your body.
A Brazil nut, also known as a para nut, has hard-walled fruit. It contains different types of proteins which is possibly the reason behind the symptoms. Apart from this, the nut also contains dietary fibres, thiamine, copper, and magnesium.
Below are the symptoms of Brazil nut allergy:
Itchiness in mouth, ears, and throat
Hives on the mouth
Swelling of the lips, tongue, mouth, or eyes
Vomiting, nausea, and dizziness
Difficulty in swallowing
Itchiness in throat, eyes, or skin
The Brazil nut allergy test looks for a specific IgE in the body because these immunoglobulins are mainly associated with allergic reactions. The particular IgE found during the nut allergy test include the following:
Flow cytometry is one of the most common methods used for the nut allergy test. It is an accurate scientific technique that is helpful in clinical diagnosis because it assesses the sample using optical, fluidics, and electronic methods.
The mechanism behind allergic reactions is that the body identifies specific components as foreign particles. Thus, the immune system starts to react against these particles to neutralise them. A particular IgE is produced in abundance during this reaction, and the nut allergy test looks for the same.
However, the first reaction is mild, and it could be asymptomatic. This is because the body is preparing itself to recognise the allergen. But, the responses after that are intense as the immune system is ready to attack and neutralise the allergen.
