Preparation For Skin Testing

Avoid Antihistamines

Histamine, a chemical mediator produced by the body, is the main chemical that helps determine positive allergies during testing. Anti-histamines are a group of medications that block the effects of histamine in the body. Due to this action, allergy testing results will be inaccurate if this medication is present within your body. Antihistamines must be held prior to testing. If you have any questions as to whether or not a certain medication will interfere with your scheduled allergy testing please contact our office. Please notify our nursing staff of ALL current prescription and over-the-counter medications at the time of your testing.

Try to Arrive Early to Your Appointment

Due to the length of time (up to 2 hours) needed to complete your allergy testing, please make every effort to arrive for your appointment on time. Arriving late to your appointment may require the appointment to be rescheduled.

Consider Your Clothing, Short Sleeves Are Best

Allergy testing will be placed either on the inner forearms and upper arms or the back. To provide better access to the upper arms, we request that you try to wear or bring a short sleeve shirt or a separate top and bottom to your testing appointment.

Expect Reactions and Some Sensitivity to Testing

Mosquito bite size reactions may remain on the skin following testing. Such reactions typically fade within 24 hours; however, rarely they may remain present up to 7 days.
