Evap lines
Please stop telling women their tests have evap lines on them unless specified that the picture was taken after the time frame or blatantly obvious that the test is dry. Evap lines are due to the evaporation of urine from the test. They are grey. They are not blue, or pink. They do not happen within 10 minutes. Invalid tests/false positives are a different story. There is no way urine evaporates that quickly. (0-10mins)
