An allergy skin test is a common procedure used to determine if a person has any allergic reactions to certain substances. (angis.org.au)
The reason why someone might need an allergy skin test is to identify any allergic reactions they may have and determine which specific substances they are allergic to. (angis.org.au)
Every skin is different, so keeping a log of skin reactions can create a reliable risk of ingredients you are allergic to. (hipgirlie.com)
It is also important to note that products marked as 'hypoallergenic' produce fewer skin reactions. (hipgirlie.com)
A gene variant, HLA-B*15:02 , found in the Han Chinese in China, Taiwan, and Hong Kong, and the Thai, Indian, and Malay populations and linked to these adverse reactions, has previously been identified, and genetic testing in these populations is now recommended before carbamazepine is prescribed.
