Pregnant or lactating women, or those planning to become pregnant within 3 months. 4. Individuals who have had other skin diseases within 6 months prior to screening that may affect the test results (such as psoriasis, drug-induced dermatitis, erythroderma, contact dermatitis, bullous diseases, severe skin infections, etc.). 5. Medication history: Those who have used topical or systemic antibiotics or antifungal drugs at the affected site within 2 weeks prior to sampling; those who have received systemic immunosuppressive therapy, phototherapy, or systemic biologic agents within 12 weeks prior to sampling (specifically determined based on the half-life of different biological agents).
