When our bodies develop rashes, itching, bloating, or unexplained fatigue, many people's first reaction is: "Am I having an allergy?" At this point, you may encounter medical terms like "IgE," "IgG," or "patch test." They are all "detectives" exploring the body's immune response, but they handle completely different "cases." Today, experts from Kuang Street will briefly introduce their respective specialties.

Quick profile of the three "detectives"️

IgE (Immunoglobulin E): "Lightning Agent"

Task type: Handling "acute allergic reaction" (Type I hypersensitivity).

Action speed: Extremely fast, usually occurring within minutes to 2 hours after contact with the allergen.

Typical symptoms: Hives, throat swelling, difficulty breathing, anaphylactic shock, acute eczema, etc. This is the most classic and dangerous type of allergy.

Purpose of detection: Confirm if you have an immediate and severe allergic reaction to certain substances (such as pollen, nuts, seafood).

Patch test: "Skin detective"

Task type: Identify the cause of "contact dermatitis" (Type IV hypersensitivity).

Method of Action: Apply potential allergens (such as metals, fragrances, preservatives) to your back skin, then observe skin reactions after 48-72 hours.

Typical Symptoms: Localized redness, swelling, itching, and blistering at the application site. Primarily used to diagnose skin issues caused by cosmetics, jewelry, hair dyes, and other products.

Purpose of Test: Identify the "real culprit" behind delayed allergic reactions after direct contact with the skin.

IgG (Immunoglobulin G): "Chronic Detective"

Task type: Associated food intolerance (delayed hypersensitivity).

Action speed: Slow, symptoms may not appear until several hours or even days after eating.

Typical symptoms: Bloating, diarrhea, constipation, fatigue, headache, rash, joint pain, and other chronic, non-specific symptoms.

Detection purpose: To explore those "quiet" chronic food culprits that bother your daily health.

Three "detectives" each perform their duties, complementing each other to establish a comprehensive allergy screening system for our bodies. In clinical settings, if there are related symptoms, you can visit a hospital offline, consult a doctor, and have the doctor decide on the appropriate tests.

Food intolerance testing + daily skincare: "Inside and outside" new advocacy

As the saying goes, "A person is iron, and food is steel," but for some people, certain foods may be the "hidden pushers" triggering discomfort or skin issues. Symptoms easing or even disappearing after avoiding certain foods is a typical manifestation of "food intolerance."

Just as traditional Chinese medicine advocates "treating both the root and the symptoms," addressing skin problems caused by food intolerance should also start from the root:

Precise Intervention: Identify problem foods through food intolerance testing and strictly implement dietary adjustments;

External Repair: Combine with scientific skincare to soothe inflammation and repair the barrier;

Internal and External Synchronization: Achieve comprehensive regulation from the inside out, helping the skin to "fully recharge" for health.

Therefore, undergoing food intolerance testing, pinpointing the core causes of skin issues, and adjusting the diet accordingly are key steps to break the vicious cycle and achieve true skin health!
