How to check baby allergies

Because the chance of allergies will increase greatly in certain seasons, especially in spring, many people are allergic to pollen, so allergists are very busy. If you want to prevent allergies from happening fundamentally, you should find a person's allergens. However, babies are very prone to allergies. How do you find babies' allergens?

Check for allergens in 3-month-old babies

Children under one year old are not suitable for allergy testing because their immune system is slowly building and maturing. The changes during this period are very slow and cannot be reflected in the test. Any test has a limit. If the test is within the limit, it is negative; if the test is outside the limit, it is positive. Therefore, it is generally not recommended to check for allergens in children who have had allergies for less than six months, because the child’s allergy history is too short and it is very likely that the child has not yet reached the level of positive allergy. However, this does not mean that the child is not allergic.

How to check for allergens in children

1. Food record method: record the types of food eaten each month, such as rice, eggs, shrimp, chicken, cucumbers, tomatoes, etc., the time of intake (such as month, day, hour, etc.), and the time when urticaria occurs.

2. Skin test: This type of test can usually be done in a dermatologist or respiratory department. The method is simple and not uncomfortable for children. Use an empty needle to inhale skin test solution containing milk, rice, soybeans, etc., and make multiple pricks on the upper arm to observe allergic reactions to various foods.

However, due to the complexity of food digestion and absorption in the body, the physiological and biochemical changes that occur cannot be fully reflected in the process. Therefore, even if the results are positive, a comprehensive clinical analysis is required to finally determine whether it is the food that causes allergies.

The process of checking allergens is complicated and requires a certain amount of waiting time. From the above introduction, we can know that 3-month-old babies are not suitable for allergen testing because the child is in the process of building their immune system. If you insist on letting your child do allergy testing at this time, the results will not be of any reference, so parents should be aware of this.
