I wanted to start a thread about test kits because I always hear that test kits are inaccurate. Even I'm guilty of saying that. But are they really? The companies that make them have been around for a long time, you would think they know how to make an accurate solution by now? What are your thoughts on that? What kind of test have you done to prove that most test kits are inaccurate? Do you think that the test kits themselves are made properly and that most inaccuracies are a result of operator error? I know we are not scientist in a lab but can we blame every high reading on a bad test?
