Our contact dermatitis clinic determines whether contact allergies cause rashy skin problems. This clinic can play an important role in the evaluation and management of eczema.
联系 dermatitis is when your skin reacts from direct contact with potential irritants or allergens such as:
- Chemicals that are present in everyday products
- 香料和防腐剂
- 金属
皮疹, 湿疹的一种, starts at the site of contact but can spread to other areas of the skin. The red and itchy rash can get worse with continued contact with the irritant or allergen.
在你的约会中会有什么期待
At your first visit or telemedicine consultation, we ask you questions about your rash history and exposures, 比如你的：
- 爱好
- 个人护理产品
- 工作
We examine your skin of the affected areas and perform a skin biopsy if needed.
接触性皮炎的斑贴试验
At your visit, we use a method called patch testing to identify potential causes of your dermatitis. We place a series of patch testing allergens on your back. We use overlying tape to ensure the patches stay in place and achieve good contact.
初始贴片测试读数
At your follow-up visit, we remove and read your first patches. Many of the substances may take longer to develop a reaction. So, we take a final reading 2 to 7 days after we've completed the patch placement.
最终贴片测试读数
During your final visit and second patch test, we read your tests and assign the strength of reactions to potential allergens.
We have an in-depth conversation with you about any positive reactions. We also give you a handout which details the possible locations of the allergens.
If appropriate, we assign you an ID from a personalized CAMP (联系 Allergen Management Program). This program allows you to find safe products to avoid allergic reactions.
联系 dermatitis frequently asked questions
Are the products I've been using for years potential allergens?
是的. You may get allergic contact dermatitis from ingredients in the products that you have been using for years on your skin.
