food combination fx5 allergy

“The essence of "food combination fx5 allergy" is a positive joint screening of 6 common ingestion allergens commonly used in clinical practice. It does not mean that you are allergic to all 6 foods at the same time: milk, eggs, wheat, peanuts, soybeans, and cod. It only indicates that you have the risk of acute allergy mediated by one or more of the above foods. The final diagnosis must be combined with single-component allergen testing and actual eating reactions. There is no need to directly avoid all 6 types of foods.

Don't tell me, last week I met a mother blocking the door of the clinic with a positive fx5 report. Her eyes were swollen like walnuts. She said that her baby had just turned 1 year old and could not even eat egg custard in the future. It was too painful. As a result, a subsequent single-component test was conducted, and it was found that only milk protein was mildly allergic, and the other five were all negative. There were no rashes or diarrhea when eating eggs and wheat supplements, and there was no need to eat any foods. In fact, many people's misunderstanding of fx5 comes from the word "combination" in the name. They think that if you are positive, you will get all the results. This is not the case at all - you can understand it as the "preliminary demining" done by the hospital for people at high risk of allergies. Scan for abnormal signals and then dig them out one by one to see if they are real mines. It will save time than searching the entire yard as soon as you get there.

Speaking of which, I was asked before, why did fx5 choose these 6 types? It’s really not a random selection. These 6 categories account for more than 90% of the causes of food allergies in children, and they can also cover about 70% of adults. With a testing fee of dozens of dollars, the initial screening is particularly cost-effective. Generally, if a child has repeated eczema or long-term diarrhea and no cause can be found, or if an adult has frequent hives or an inexplicable itchy throat after eating, the doctor will first prescribe fx5 to check the results. If it is negative, it can basically rule out these six categories of acute allergies, saving you the expense of spending hundreds of dollars to check dozens of unnecessary allergens.

Of course, doctors in different fields do have different opinions on the clinical significance of fx5. Most doctors in the general allergy department will use it as a preliminary screening tool for IgE acute allergy. As long as the single component test is negative and there is no reaction after eating it, there is no need to eat it at all. ； But doctors who practice functional medicine tend to be more cautious. If your fx5 value is particularly high, even if you have a single-component all-yin and no obvious acute allergic reactions, they will recommend that you avoid it for 2-4 weeks to see if minor problems such as long-term fatigue, chronic rhinitis, and unexplained acne will be relieved. After all, the manifestations of allergies are inherently strange, and there are still many things that medicine does not understand. There is no need to stick to one standard.

The most exaggerated case I have ever encountered was a young man in his 20s. His fx5 value was so high that he was only slightly allergic to cod after a single component check. He said that he has loved eating deep-sea fish since he was a child. He did not experience rashes or diarrhea after eating it, but he would have a bit of nasal congestion the next day after eating it. I always thought it was chronic rhinitis due to the change of seasons. Then I tried to stop cod for 3 months, and the rhinitis actually healed on its own. Isn’t it magical?

By the way, there is another common pitfall. Many people feel that they are not allergic to all foods after checking the negative FX5. This is not right. After all, it only covers the 6 most common allergens. If your mouth swells up every time you eat mangoes or you have diarrhea every time you eat kiwi, just check the corresponding single allergen directly. Don’t be misled by the negative FX5. There was a girl who tested positive for fx5 before when she was preparing for pregnancy, so she stopped all eggs and milk. Her protein level in the early pregnancy was so low that she was almost hospitalized. Later, the only component of the test was peanut allergy, and everything else was fine. She took supplements for half a month before the egg and milk indicators came back. She suffered a lot.

To put it bluntly, whether it is fx5 or other allergen tests, they are only a reference for doctors and patients. The real gold standard is actually your own body's reaction - you feel comfortable after eating, even if the report says you are highly allergic, don't be afraid； If you feel uncomfortable after eating it, you should avoid it even if it reports a full yin. After all, the body is the most honest detector. If you are really unsure, finding a reliable allergist to judge based on your medical history is far more useful than blindly following the report yourself.
