If your child has a positive reaction, your child is considered allergic to that venom. These reactions usually go away in 30 to 60 minutes. It is possible to be allergic to more than one kind of venom.
Your child may have swelling and itching at the testing site four to eight hours after the test. You may use an over-the-counter hydrocortisone cream to help with this.
Your child may have a skin reaction at the testing site several hours after the test is done (this is called a delayed local skin reaction). This reaction is typically not serious and should go away during the next two to three days. If you are worried about a delayed reaction, call 617-355-6117 and ask to speak with an allergy nurse.
