Improper Storage - Pregnancy Test?

It's probably correct -- the lady who runs peeonastick.com has done all sorts of things to pregnancy tests to see how they work, including microwaving it for 5 minutes to see if it still works. The results? Still turned up negative, when it was supposed to be negative, but with a fainter control line. Chances are that if it were damaged from the heat, it would give a false negative instead of a false positive. But you should probably test again just to be sure. Tests also have expiration dates on the individual foil package and/or the box.
