YOU SAID:

I don't quite think those tests work as long as they say because those expired Jan 11 but they were expired in June so they may lay longer but might not work as well as long as they say

INTO JAPANESE

これらの検査は1月11日に期限切れだったが、6月に期限切れになったので、もっと長く続く可能性はあるが、言われているほど効果があるとは思えない。

BACK INTO ENGLISH

These tests expired on January 11th, but they expired in June, so they may last longer, but I doubt they will be as effective as said.
