Understanding delayed-type
Delayed-type testing in dermatology, or 지연성알러지검사 in Korean, refers to procedures that detect immune reactions unfolding over hours to days. These tests contrast with immediate IgE-based assays that trigger quick symptoms. In practice, they include patch tests for contact allergens and, in some clinics, dietary IgG panels.
Patch testing is a standardized method used to identify contact sensitivities that can irritate the skin. A small amount of allergen is applied under patches and observed after 48 to 72 hours. Interpretation depends on the pattern and timing of the reaction, not just a single reading.
Delayed-type tests have limited utility if used alone. Clinical history remains essential to distinguish true sensitization from incidental findings. Korean dermatology clinics increasingly integrate these tests with comprehensive skin exams.
IgG based skin tests
IgG based skin tests measure antibodies to various foods or antigens and report sensitivity patterns. The rationale is that elevated IgG levels may reflect exposure and tolerance rather than intolerance. Many clinics consider these results when advising dietary changes for skin conditions.
However, evidence linking IgG positivity to symptom triggers is inconsistent. Results can lead to unnecessary dietary restrictions and nutritional risk. Interpretation should always be done by a dermatologist in the context of symptoms.
Patients often ask about test reliability and what to do next. Sensitivity and specificity vary by laboratory and panel. A cautious approach includes keeping a symptom diary and working with a clinician.
Food triggers on skin
Diet can influence skin inflammation in susceptible individuals, but effects are not universal. Common concerns include acne flare ups, eczema flares, and generalized itching. Understanding the role of foods requires careful, patient-specific evaluation.
Clinical practice often starts with history taking and food diaries. Some patients notice changes after dairy, high glycemic foods, or certain grains. Reactions may be delayed, inconsistent, or influenced by other factors such as stress.
When a diet change is considered, it should be gradual and supervised. Reintroductions help determine true triggers without compromising nutrition. Dermatologists may coordinate with nutritionists to maintain balanced meals.
Korean skin care clinics
Korean dermatology clinics form a dense network with a diverse range of cases. Clinicians often manage complex inflammatory skin diseases alongside allergy assessments. Access to patch testing and, in some centers, IgG panels reflects local demand.
Cutting edge laser and resurfacing technologies are routinely combined with allergy-informed care. This integrated approach aims to address both surface symptoms and underlying triggers. Patients benefit from personalized plans developed through collaboration between dermatologists and allergists.
Interpreting delayed-type results remains nuanced in Korea as in many countries. Over interpretation can lead to unnecessary diet changes or testing fatigue. Ultimately, decision making relies on symptom patterns, clinical exam, and evidence-based guidelines.
