預 防 醫 學
We eat a variety of foods for three meals a day, but we may eat unsuitable foods (allergens) because we do not understand our own constitution and the causes of allergies. These foods are regarded as enemies by the body’s immune system to fight, and the body becomes inflamed, damaged, and consumed internally. This is allergy.
Acute allergy (type 1 allergic reaction) comes from the IgE antibody in the body. After IgE combines with the allergen, it induces the body to release histamine, leukotrienes and other substances, causing acute symptoms such as runny nose, urticaria, and dyspnea.
Chronic allergies (type III anaphylaxis), also known as food intolerance, are usually caused by IgG antibodies. IgG forms immune complexes with allergens, and gradually accumulates in body tissues along with the blood flow to form a chronic inflammatory response. Often cause skin, respiratory tract, digestive system and other symptoms. Due to the slow onset and complex symptoms, it is easy to be ignored or misjudged.
Acute allergic symptoms are fast and violent, and there will be an allergic reaction within about 30 minutes after touching or eating. Most people sometimes know that they are allergic to certain foods through their own experience.
Chronic allergies are different from acute allergies. The symptoms of chronic allergies do not occur until about 24-48 hours (or even 72 hours) after contact or ingestion. The symptoms of chronic allergies are usually more complicated, so it is difficult to accurately predict whether to eat within 3 days In addition to the complex diet of modern people (a dish may contain 5-6 kinds of ingredients), the only way to know the cause of chronic allergies is to rely on testing.
Three major factors that cause allergies
Family inheritance. envirnmental factor. eating habits
There are many allergens in life, environmental factors only account for 23%, dietary factors are as high as 77%!
One-time inspection benefits life-long, chip-type allergen detection is different from traditional detection, only one time, 2ml of blood is drawn, and you will stay away from allergens from now on.
1. Patients with allergies.
2. People with allergic constitution.
3. One or both of the parents are allergic.
4. Pregnancy and breastfeeding period: 9 months from pregnancy to birth is the golden period to reduce the chance of giving birth to a baby with allergies;
It can also cause baby allergies.
5. School-age children: Children’s immune system is not yet sound, and they are easily affected by allergens. GE224 allergen detection can be used to understand the cause of allergies, and
6. Focus on personal health managers.
Q: What is the difference between acute allergies and chronic allergies?
A: The symptoms of acute allergies are fast and violent. Once touched or ingested, there will be an allergic reaction within about 30 minutes. Most people sometimes know that they are allergic to certain foods through their own experience. Chronic allergies are different from acute allergies. The symptoms of chronic allergies do not occur until about 24-48 hours (or even 72 hours) after contact or ingestion. The symptoms of chronic allergies are usually more complicated, so it is difficult to accurately predict whether to eat within 3 days In addition to the complex diet of modern people (a dish may contain 5-6 kinds of ingredients), the only way to know the cause of chronic allergies is to rely on testing.
Q: What is the value of chip-based allergen testing?
A: The traditional allergen testing in the hospital is only for acute allergies, and there are few items (up to 36 types), and it can be roughly mastered according to the patient’s own experience. In addition, traditional allergen testing cannot provide complete follow-up recommendations, so the value is naturally low. The chip-type allergen test of Leaper is completely different. It not only fully evaluates acute and chronic allergies, but also has the most testing items (up to 123 types). The value of Transcend allergen detection:
1. Complete understanding of personal physique.
2. Provide personal advice on healthy (hypoallergenic) diet.
3. It can improve allergic constitution and improve health.
Q: How accurate is the current allergen screening?
A: The accuracy and specificity of the clinical test results of the positive control serum collected so far are as high as 90%, which is on par with or surpasses the current allergen detection system on the market, and it saves costs and improves efficiency.
Q: How often do allergen tests need to be done?
A: Do it at least once in your life, and it is generally recommended to do it once a year
Q: What age is suitable for allergy testing?
A: Generally, it is recommended that children over 3 years old are more suitable for allergen testing. The reason is that children over 3 years old eat a wider variety of food and more complete, so it is more valuable to do testing; but if children under 3 years old, if there are obvious Allergy symptoms can also be tested.
Q: For foods that have never been touched, can the severity of food allergies be measured?
A: No. The principle is the same as that of children under 3 years old. Foods that have never been touched before will not be sensitized for the first time, and there will be no subsequent allergic reactions. Therefore, it is recommended to test a food after eating it several times. Find out if you have acute or chronic allergies to this food.
Q: Can I be tested if I am currently taking medicine or eating health food regularly?
A: Yes. Drugs containing “steroids” mainly affect the results of allergy test reports. High doses or long-term use of steroid drugs will reduce the test value. Among them, edible and injectable steroid drugs have the greatest impact, and the rest are sprayed and rubbed steroids. Drugs are less affected.
Q: Can pregnant women do allergy testing?
A: Both pregnancy and postpartum lactation are acceptable. It is recommended to do the test before the 4th month of pregnancy, which will help the most:
1. It can reduce the occurrence of mother’s personal allergy.
2. Reduce the risk of the fetus becoming an allergic child.
3. Provide low-sensitivity dietary advice for breastfeeding.
Q: Will the test results at different stages be the same?
A: Not all the same. With the change of life or eating habits, long-term avoidance of contact with the allergen, or receiving drug treatment, the concentration of IgE and IgG will decrease. In addition, when the subject is exposed to a new allergen, it may also appear that the last test did not detect a new allergy item this time. Therefore, it is recommended that people with allergies should be tested once a year to continuously monitor allergies.
(Example: The test results may be almost the same between today and 3 days later; but if you compare the test results today and a few months later, the test results may be significantly different.)
