Query: Criminal

No test object is included in the kit. I have a cup which I knew had lead from a previous test. The kit I bought Dec. 5th, 2012 failed to detect the lead. It may have been in the store too long. There is no expiration date on the package. To sell a kit which may mislead people who follow the instructions in a matter like this is criminal.
