The test kit is hard to read, you could get three different readings from the same sample. If you don't use the kit right you could end up ODing. If you don't clean out the test tube right after a test the tube will become stained and give a copper reading with just RO water. If you hold the tube to close to the card the water will take on the color of the nearest ppm color. And if you hold it not close enough it will make you think that it's not enough copper in the system. Bottom line unless you are just trying to see if any copper is present in your system don't use. If you are medicating get another brand test kit.
