Buy from a reputable seller for anything important, instead of amazon.

Or, there are apparently at-home testing chemicals that look simple to use. I haven't done it myself though.

The question is who is reputable. Even when buying from a well known store, I don’t know how they audit their suppliers, because the paper is bound to be made by some company I’ve never heard of.
