What should I pay attention to during the allergy attack period physical examination?

Before the physical examination during the allergy attack period, it is necessary to inform the doctor of the allergy history and suspend contact with allergens. Those with severe allergic reactions should postpone routine physical examinations. Allergic reactions may interfere with the accuracy of some test results such as blood routine and skin tests. During an allergic episode, the immune system is in a highly sensitive state, and IgE mediated rapid hypersensitivity reactions may lead to an increase in peripheral blood eosinophils, interfering with the white blood cell classification count in blood routine tests. Skin prick test, patch test and other allergy tests may produce false positive results, and serum total IgE levels may also be abnormally elevated. Enhanced CT examination with injection of contrast agents poses a risk of inducing severe allergies, and it is necessary to evaluate the necessity before switching to plain scan or other alternative methods. Taking antihistamines may mask the symptoms of skin allergies and affect doctors' assessment of the condition. disinfectants, latex gloves, and other items used by some medical examination institutions may contain potential allergens, and it is necessary to communicate in advance to replace hypoallergenic consumables. Individuals with mild allergy symptoms can complete the basic physical examination items, but should avoid easily interfered items such as allergen testing and lung function tests. Priority should be given to examinations such as electrocardiograms and abdominal ultrasound that are not affected by allergies. Skin tests for drugs such as penicillin should be postponed until 2 weeks after complete relief of allergic symptoms to prevent false negative results. On the day of physical examination, individuals with allergies should carry an adrenaline automatic injection pen as a backup to avoid triggering hypoglycemic reactions due to prolonged fasting time. Patients with a history of allergy to contrast agents should register with the radiology department and, if necessary, use corticosteroids and antihistamines for preventive treatment. A comprehensive physical examination 1-2 weeks after the end of the allergy attack period can obtain more accurate results, during which the frequency and causes of allergy symptoms should be recorded. It is recommended to choose the season with the least allergic symptoms for routine physical examinations. Those with pollen allergies in spring should arrange for autumn physical examinations, while those with dust mite allergies should avoid the rainy season. Medical examination institutions should be equipped with emergency equipment capable of handling anaphylactic shock, including adrenaline, oxygen, and airway management tools. For people with food allergy, it is necessary to confirm that the nutritional meal provided by the physical examination center does not contain allergenic ingredients, and diabetes patients should avoid sugary contrast agents. Allergy specialists can develop personalized physical examination plans based on individual conditions, and complete examination items in stages if necessary.
