Another rip off test kit which is not needed.
First steps to do if you are a home owner and wondering about Chinese drywall:
Check all copper piping, plumbing, a/c as the air handler unit, ground wires at receptacles and switches. If turning dark and being coated with a substance which rubs off on your fingers ... MAYBE. If turning dark and it does not rub off on your fingers, probably normal tarnishing.
Go by the Big Box stores or your local hardware store and buy some copper plumbing fittings, lay them around the house. If they turn dark and the substance rubs off ... MAYBE.
If you have a medicine cabinet which is recessed into a bathroom wall, remove it (usually 2 to 4 screws is all) and look inside that wall - easy to do and you can see if there is anything that says China or Knauf in there, or Made in China on the paper strip along the joint.
Do you have silver jewelry which is tarnishing, you polish it and it tarnishes again in a few weeks? Are the backs of your mirrors turning around the edges (most mirrors are coated with silver on the back - that is what makes it reflective). Then MAYBE.
Do you smell sulfur or a sulfur like smell ... MAYBE.
IF the above is there, especially more than one of the above ... MAYBE.
Then a sample would need to be taken and tested at a real laboratory for the elements it contains - only that way will you know what the drywall contains.
