Review title is Does NOT Work [SEP] I was recently diagnosed with a nickel allergy. I bought this test hoping to get help figuring out what things in my house I should avoid touching. I am very disappointed that the test doesn't work. I tested my brushed nickel appliances as control and got zero results. It obviously doesn't work. Now I have to look for another solution and I'm still not sure what things are in my house that can make me sick. I would give it a zero rating.
