Patch Testing for Allergies in Brooklyn, NY & Upper East Side, NY

Patch testing is a crucial method used to identify specific substances that may cause contact dermatitis and other allergic skin reactions. This test is particularly useful for detecting allergies to substances like cleaning agents, detergents, cosmetics, perfumes, latex, and plant oils like those from poison ivy.


Patch Testing at Kleydman Dermatology

During patch testing, multiple patches containing potential allergens are applied to the skin, typically on the upper back. These patches must remain in place for 48 hours, during which time the skin should be kept dry. Patients are advised to monitor for any severe reactions, such as significant irritation or respiratory difficulty, and remove the patches if necessary.


Poison ivy, known for causing allergic skin reactions in many individuals, contains an oil called urushiol that triggers rashes. These rashes are not contagious but can be very uncomfortable and unsightly. While a poison ivy rash typically resolves itself, extensive rashes may require longer to heal.


Home remedies for alleviating symptoms include:

  • Baths in colloidal oatmeal
  • Application of hydrocortisone cream
  • Over-the-counter antihistamines and pain relievers
