Most all--if not all, test kits have an expiration date, or time period, beyond which they cannot be relied upon. Would say your kits are way past the expiration. I believe it to be two years, however, it may be less. The expiration date should be printed on the cardboard box of the kit.

I wouldn't trust them.

However if you want to try have your LFS run their test kits and compare results with your test kits.
