Is it necessary to test for baby allergens? Why?

It is necessary, because the baby is still young, the immunity is low, the language development is not very perfect, if the baby is allergic, can not speak, will cry, know the baby's allergens in advance, can avoid allergies to the baby's harm.

It is necessary to test the source of the baby's allergies, because in this way the baby can stay away from the allergen, and it can also avoid the baby's allergic symptoms from the source.

It is necessary to test, because after verifying the baby's allergens, you can avoid contact with allergens and avoid baby's allergies.

There is no need.

Allergen testing is not a tube of blood that can determine what you are allergic to. First of all, the types of allergen testing items are limited, not all substances will be tested once, and only a limited number of more than 30 substances will be tested; Secondly, the results of allergen testing need to be combined with the actual situation after exposure to comprehensively analyze whether it is a real allergen. Rather than testing positive, it means that you must be allergic to this substance; Finally, allergen test results are not permanent for life, and one result is not indicative of what will continue to be the case in the future.

If the child drinks milk at the age of 6 months and shows frequent vomiting, diarrhea, blood in the stool, eczema is significantly aggravated, or acute urticaria and other corresponding symptoms, then milk protein allergy should be considered; Conversely, if the child has a positive test for allergens but does not have any symptoms after drinking the milk, then allergies are usually not considered.

At present, the latest guidelines point out that eczema is mostly related to the imperfect development of the ** barrier, and there is no direct relationship with allergies. Food allergies often lead to rapid response illnesses such as acute hives. If your child has a rapid** reaction every time he or she eats a particular food, consider testing for allergens, especially milk, eggs, peanuts, wheat, and soybeans.

At present, the child is 2 years old and does not have any symptoms of discomfort, so there is generally no need to go for an allergen test.

Introduction: In recent years, with the change of lifestyle and environment, there is a trend of increasing allergic diseases in children. The pathogenesis of allergic diseases is complex and is thought to be closely related to genetics and environment.

When it comes to toddler diets, babies under 1 year of age are best breastfed. Milk, shrimp, eggs, seafood and other isomeric protein foods should be carefully given to children. In addition, pregnant women should not eat foods containing allergens and should not be fed hypoallergenic hydrolyzed protein infant formula.

At the same time, the addition of non-staple foods should be delayed. Children should not engage in strenuous exercise in a dry, cold environment. Exercise should be done in a warm, humid or intermittent environment.

For children with allergies, parents don't have to worry too much. As long as you pay attention not to contact allergens in your daily life, as long as you are sick in time**, regular medication, most children will be cured.

Allergens are necessary to test, because in this way you can know the baby's physical condition, can avoid allergens well, can use other foods to supplement nutrition, so that the baby's body is better, if the baby is allergic, it is likely to cause problems in the baby's **.

It is definitely necessary to check, because after the examination is clear, we can avoid the baby's allergies, and then we will also remember that these foods will not be given to the baby in the future.

This is necessary because many children suffer from allergic diseases such as eczema, allergic rhinitis, and even allergic asthma. At this time, if you don't know which allergen the child is allergic to, it will cause the recurrence of allergic diseases, and it is difficult to control it fundamentally. If children are allergic to fish and shrimp, they usually eat less fish and shrimp or prohibit eating fish and shrimp, which is very helpful for the control of children's allergic diseases.

Some children are not sure of allergies, but they can also be tested for allergens to determine whether they are allergic.

It is necessary to test, the baby's allergies will be particularly itchy, and they will often scratch with their hands, always follow the mother and often rub their legs around.

I think it is necessary to test, because the baby is very uncomfortable with allergies, and only when the allergen is found can it be treated in time, the baby may have erythema, and it will be very itchy, and even he will cry very easily, very irritable.

I felt the need to go for a test so that he could protect the child. There will be acne, and there will be ** redness and swelling, there will also be poor sleep, there will be sneezing, and there will also be fever.

In order for the baby to grow up healthily, when can I check the allergen?

**Puncture test**The site of the puncture test is the volar side of the forearm**In the puncture test, in order to determine the **responsiveness of each patient, a saline negative control and a histamine positive control must be used. During the examination, relax the arm, put it on the table, and clean the test site with normal saline. The needle is inserted, so that the test solution that has been dropped into ** passes vertically and penetrates briskly**. If there is any test solution residue, the reaction is normal, and it can be wiped off after 10 minutes; If you have a strong reaction, wipe it off immediately.

The test results were read out 30 minutes after pricking, but the reaction process was observed several times during this period; When the crest is present, there is erythema around it, which is a positive test reaction.

When the reaction intensity expressed as ** is similar to histamine**, the reaction is marked accordingly, and when it is weak, it is marked. When the negative control reaction, add. **Contraindications for puncture examination of allergens:

People with positive scratches, high allergies, pregnant women, infants and the elderly are prohibited from allergen testing; If you take antihistamines, antihistamines, or glucocorticoids within a week, you may have a false-negative result due to taking allergy medications at the time. Enzyme-linked immunoassay (ELISA) to detect allergens This method is a blood test for specific IgG in the blood, which is simple, safe and reliable, at any age and without any conditions, patients can suck 3ml of venous blood.

This method avoids the complex operation process of the commonly used in vivo allergen detection directly in the patient's body for a long time, overcomes the susceptibility of the allergen detection in the body to the influence of factors such as ** state, drug use, operation, etc., and has the hidden danger of inducing systemic severe allergic reactions, and it is easy for children with severe allergies and people who are sensitive to pain to accept. The most common allergens inhalation allergens: house dust mites, dust mites, pollen, animal fur, mold, etc.; Ingestion allergens:

crabs, fish, eggs, milk, fruits and nuts, certain mushrooms, etc.; Contact allergens: wool, dyes, cosmetics, toxic ivy, silver, latex gloves, etc.; Injected allergens: Drugs that insect bites with venom.

Generally, the child can go to the hospital at about 6 months old, and the source of the child's allergies can be found. It's also okay when you're one year old.

At this time, you can go to a professional pediatric hospital, and then check for allergens by drawing blood, and the results of the general examination are more formal and comprehensive.

You can do it at any time, but allergens are subject to change, depending on your physical condition during this time.

In order for the baby to grow up healthily, I think you can check the allergens when the baby goes to kindergarten, because the baby is not at home before going to kindergarten, eating and drinking and living are all done by yourself, it is impossible to have allergens, that is, after going to kindergarten outside, more things are exposed, so generally the baby has to check the allergens before going to kindergarten, so as to ensure the healthy growth of the baby.
