Patrina Posted February 4, 2021 Share Posted February 4, 2021 Does api test kit being expired change the results of test? Link to comment Share on other sites More sharing options...
Squeegee79 Posted February 4, 2021 Share Posted February 4, 2021 Unfortunately the only way to know would be to compare it to one that has not expired. Personally, I would replace it as most things break down over time. I can only assume test kits do as well. Link to comment Share on other sites More sharing options...
Nana Finopolis Posted February 4, 2021 Share Posted February 4, 2021 I have an expired one as well as a new one. I used both just for that reason and the results were identical. Your mileage may vary, but that was my experience. Link to comment Share on other sites More sharing options...
BlackLabelCarling Posted February 7, 2021 Share Posted February 7, 2021 (edited) The only thing you have to watch for (in my experience) is the ammonia solution crystalizes a little bit over time. I have to give the bottle a good smack on a hard surface tom loosen it up, otherwise the reading is inaccurate.
