My son was tested when he was 2 1/2 for allergies . He also had the blood test. It checks for peanuts,treenuts,wheat,soy,milk,egg,gluten,shellfish,and plant mold. It is worth it because you will find out the severity of each one also. The scratch test is painful and unneeded if many allergies aren't suspected. By the way, my husband took our son for the bloodtest. he was great and didn't cry.Good luck to you :)
