i don't know and i have never had a patient ask me to test for hamster dander. i am not even sure if this is available. you can get a hamster and test it out using your child as a "guinea pig" (no pun intended). if he experience allergic symptoms then you will likely have your answer and you can find a new home for the hamster. don't spend lot on the hamster equipment; just the basics until you know. remember a few things: hampsters tend to be nocturnal (more active at night) so they love to run on those noisy wheels when you are trying to sleep. they are great escape artists so he is most likely to get out and go free-range in your house. and hamsters bite and five year olds tend to get bit because they are not as gentle with pets as they should be. think about a goldfish.
my 5yr old is allergic to dogs and cats being that he is allergic to dogs/cats would he be allergic to hamsters also?
