Dust mites are tiny animals that are generally invisible to the naked eye and can only be seen under a microscope. If a dust mite allergy occurs, it can cause many skin symptoms, such as acne, itching, pigmentation, or erythema, severely affecting the patient's quality of life and appearance. Therefore, if a dust mite allergy is present, it is important to pay attention to personal hygiene and skin cleanliness, and maintain ventilation in the house. Treatment can include the use of anti-allergy medications.

How to Test for Allergens in Allergic Rhinitis

Allergic rhinitis is considered an autoimmune disease, mainly triggered by the body's immune response after contact with allergens, leading to related clinical symptoms such as itchy nose, runny nose, and sneezing. Generally, it is necessary to conduct an allergen test. Currently, there are mainly two methods for allergen screening. The first is the skin prick test, and the second is a blood test. Both methods are commonly used clinically. Relatively speaking, the skin prick test may induce higher risks of side effects or allergies. Some patients may need to undergo both tests and look at the results comprehensively, but most patients can choose one of the two.

How to test for allergens in allergic rhinitis?

Allergic rhinitis is very common in daily life, and its main trigger is the inhalation of allergens in the air by patients. In the south, the allergens are mostly mite allergies, with an incidence rate of over 90%. In daily life, allergic rhinitis can also be caused by food, hair, pollen, and other allergens. The most common method to identify allergens for allergic rhinitis is the use of an allergen test kit, through a skin prick test to determine the patient's allergens and the degree of allergy, etc. A series of targeted anti-allergy treatments can then be carried out to achieve a cure for allergic rhinitis.

Alcohol allergy symptoms

If a patient is allergic to alcohol, the following symptoms may occur: the patient will feel itchy all over, their skin will turn red, and they may experience welts and rashes. Some patients may also experience chest tightness, shortness of breath, palpitations, dizziness, and even fainting, profuse sweating, and transient loss of consciousness. If a patient exhibits profuse sweating along with transient fainting and loss of consciousness, this indicates a severe condition that requires emergency medical treatment at a hospital. Anti-allergic measures should be taken to alleviate the allergy symptoms. Additionally, due to the allergy, the patient may experience a relative insufficiency in blood volume, necessitating fluid replenishment treatment. Therefore, patients with an alcohol allergy should avoid exposure to alcohol to prevent triggering allergic symptoms and endangering their lives. (Medications should be used under the guidance of a doctor.)

When is the best time to check for allergens in allergic asthma?

The best time to check for allergens in allergic asthma is still during an asthma attack. At this time, due to the body's strong immune response to external allergens, also referred to as a hypersensitive reaction, checking for allergens can likely yield some positive results. However, there are many methods for screening allergens, such as drawing blood to check for IgE antibodies, or using skin prick tests to assess reactions to different allergens. However, if it is during the acute phase of an asthma attack, it is recommended to use the blood drawing method, which is relatively safer. Using skin prick tests might exacerbate the patient's allergic reaction, and may even lead to an acute asthma attack, or severe asthmatic conditions. Therefore, there are significant considerations to be made when choosing different methods for allergen testing.

Drug allergy symptoms

Drug allergies mainly manifest as skin itching, red rash, and papules; severe cases may experience ulceration, exfoliative dermatitis, in the respiratory system it may present as nasal congestion, breathing difficulties, and laryngeal edema; in the digestive system, patients may experience abdominal pain and diarrhea, sometimes accompanied by joint pain and swelling, immune dysfunction, and the occurrence of allergic purpura. Some drug allergies can cause neurological reactions, such as dizziness and headaches. When a drug allergy occurs, immediately stop using the suspected medication, and simultaneously take anti-allergy medications such as loratadine, cetirizine, or administer diphenhydramine via muscular injection. Oral intake of compound glycyrrhizin capsules may be considered. If there is laryngeal edema, it is crucial to seek prompt medical attention at a hospital, actively manage the allergy, and severe cases may require a tracheotomy for rescue. (Specific medication usage should be conducted under the guidance of a doctor, and medications should not be used without authorization.)
