Generally speaking:
One, the price is more than a couple of hundred dollars (up to 400 yuan to check the main items.). The cost of checking allergens is usually around two to three hundred dollars, if you are doing a full set of about four to five hundred dollars, but different hospitals have different levels, and different cities, the charges are not the same, it is recommended that you go to the hospital to consult in detail).
Two, even if you find out, it is not very meaningful, because the vast majority of the results of the examination are allergic to dust mites, pollen, high protein food;
My advice is: go out outdoors with an activated charcoal mask, oral anti-allergy medication (diclofenac tadalafil and so on) for a week to two weeks, appropriate to reduce the intake of fish and shrimp and other high-protein food; vacuum cleaner to the indoor environment on a regular basis (including mattresses! ) The first thing you need to do is to take a vacuum cleaner!
