When our bodies develop rashes, itching, bloating, or unexplained fatigue, many people's first reaction is: "Am I allergic?" At this point, you might come across medical terms like "IgE," "IgG," or "patch testing." They are all "detectives" investigating the body's immune responses, but each is responsible for entirely different "cases." Today, the experts from Broad Street will give you a brief overview of their respective specialties.
Three "Detectives" Quick File
IgE (Immunoglobulin E): "Lightning Agent"
Task Type:Management of "Immediate Hypersensitivity" (Type I Hypersensitivity).
Action Speed:Extremely rapid, typically occurring within minutes to 2 hours after exposure to the allergen.
Typical symptoms:Urticaria, throat swelling, difficulty breathing, anaphylactic shock, acute eczema, etc. This is the most classic and dangerous type of allergy.
Detection Purpose:Confirm whether you have immediate, severe allergic reactions to certain substances such as pollen, nuts, or seafood.
Patch Test: The Skin Detective
Task Type:Find the Culprit Causing Contact Dermatitis Type IV Hypersensitivity Reaction
Mode of Action:Apply potential allergens such as metals, fragrances, and preservatives to the skin on your back, and observe the skin reaction after 48-72 hours.
Typical symptoms:Local redness, swelling, itching, and blistering at the application site. Mainly used for diagnosing skin problems caused by cosmetics, jewelry, hair dyes, etc.
Detection Purpose:Find the real culprit of delayed allergy after direct skin contact
IgG (Immunoglobulin G): "The Chronic Detective"
Task Type:Associated Food Intolerance (Delayed Hypersensitivity).
Action Speed:Slow, symptoms may appear several hours or even days after eating.
Typical symptoms:Abdominal distension, diarrhea, constipation, fatigue, headache, rash, joint pain, and other chronic, nonspecific symptoms.
Detection Purpose:Explore the chronic food culprits that quietly affect your daily health
Three 'detectives' each have their own responsibilities, complementing each other to establish a comprehensive allergy screening system for our bodies. If there are related symptoms in clinical practice, you can seek offline medical consultation, consult a doctor, and have the doctor prescribe appropriate tests as needed.
Food Intolerance Testing + Daily Skincare: A New Approach of "Internal and External Care"
As the saying goes, "Man is iron, food is steel," but for some people, certain foods may be the "invisible driver" that triggers discomfort or skin problems. The relief or even disappearance of symptoms after avoiding certain foods is a typical manifestation of "food intolerance."
As advocated by traditional Chinese medicine, "treating both the symptoms and the root cause," addressing skin problems caused by food intolerance should also start from the root
Precise Intervention:Identify problematic foods through food intolerance testing and strictly implement dietary adjustments
External Repair:Combined with scientific skincare, it soothes inflammation and repairs the barrier.
Internal and External Synchronization:Achieve holistic regulation from the inside out, helping skin health return to full vitality.
Therefore, conducting food intolerance testing, identifying the core causes of skin issues, and making targeted dietary adjustments are crucial steps to break the vicious cycle and achieve genuine skin health!
