We prescribe a numbing cream called EMLA which is a lidocaine based cream for the testing. This is to make the testing experience less uncomfortable for you or your child. This needs to be put on one hour before the testing.
How To Properly Use EMLA Before Your Testing
Apply the EMLA cream to the appropriate place on the skin (as outlined below based on what type of testing you are coming in for), but do not completely rub it in. We want to have a thin layer of the cream still remaining on the skin like icing on a cake. Once this is done, you need to wrap the skin in saran wrap to ensure the cream stays on the skin. This will help the numbing medicine within the cream to penetrate deeper and better anesthetize the skin. This will not cause any immobility of the arms or trunk. It will only anesthetize the skin where the cream is in contact. The skin may look blotchy, red, and be a little itchy. This is normal and will go away once the saran wrap is removed.
Where To Place The EMLA Cream
If you are coming in for Food testing, then the EMLA cream needs to be put on the back from the top of shoulders to the waist, and then wrapped in saran wrap as described above.
If you are coming in for Environmental testing, the cream needs to be applied to the back from the top of shoulders to the waist AND both anterior forearms (the part of the forearms where your palms are turned up) from the wrist up to the elbow crease.
If you are coming in for Venom or Antibiotic testing, the cream needs to be put on both anterior forearms (the part of the forearms where your palms are turned up) from the wrist up to the elbow crease.
