Are there any risks to the test?
There is very little risk to having a patch test. If you feel intense itching or pain under the patches once you are home, remove the patches and call your health care provider.
There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.
After a biopsy, you may have a little bruising, bleeding, or soreness at the biopsy site. If these symptoms last longer than a few days or they get worse, talk to your provider.
