Do you throw away your pregnancy test?

Question

pregnancy test?" /> 
Everytime I take a test and it’s negative I just throw it in the trash. But I’ve seen on here that you ladies keep them and sometimes a line pops up an hour later?

Accepted Answer

After I believe 5-8 minutes, the test is considered invalid. So keep them for a few minutes then trash them. Usually the late lines are evaporation lines.

Answer

Results after 10 minutes are considered invalid on most if not all tests.
