If you're having an allergy skin test, plan to spend about an hour
for the entire appointment. For the scratch and intradermal skin tests,
the allergen placement part of the test takes about 5 to 10 minutes.
Then you will have to wait about 15 minutes to see how your skin reacts.
Patch tests take longer, as you must wear the patch for about 48
hours to determine if there is a delayed reaction. During this time,
bathing and swimming should be avoided. You will return to the doctor
after the specified period of time to have the area(s) checked.
