Every one is different. Just because you passed doesn't mean someone else will pass. The half-life ranges from 0.8 days to 10 days depending on the person and many factors.

The home tests are about 97% accurate. Every once in a while 1 or 2 people out of 100 will pass a home test but fail the real test. Sometimes it is due to slight changes in fluid intake from one day to the test day, other times it is because people fail to use the first void. 2 tests are a great sign because just in case one test wasn't stored properly and inaccuarte you have two negative results.
