How is the Test Performed?
The antigen is injected just under the skin, usually on the forearm, so that a small lump pushes the skin up. The lump indicates that the antigen has been injected at the correct depth. The site is labeled, usually with an ink pen.
After 48 to 72 hours, if the immune system is able to react to antigens, the skin will appear red or irritated where the antigen was injected. The size and degree of irritation will determine whether you are responding to the antigen. A second visit after 48 to 72 hours is required to have the results confirmed. You may be given washing instructions so that the test will be accurate.
