I recently took the Biosure Home Test. At first i didn’t push the test hard enough down to the bottom of the pot. So when I checked after 5 minutes it hadn’t started running. After pushing a bit harder I managed to push it right to the bottom of the pot and the test started running. I almost immediately saw the control line. After that I waited for additional 15 minutes and the test came back negative (no test line). Is there a possibility that I got a false negative because the test didn’t run immediately after I drew blood or is it ok as long as I saw the control line? Thanks for your help.
