I have seen many a pic online, here and elsewhere of hpts taken out of their casing. Is there a correct method to opening these suckers? What's the protocol? I figure you can't open it during the test time, cause that may mess with the test. You can't open it after it's dried cause whatever it shows will be invalid anyway after the time limit. So what do you do?
Does opening the test makes a positive test line appear?
