The First Response test is so sensitive that most pregnant women have enough of the pregnancy hormone, hCG (human chorionic gonadotropin), to be detected as early as five days before their expected period. Therefore, you can use the First Response Early Pregnancy Test as early as five days before you expect your period. For example, if you expect your period on the 21st day of the month, you can test as early as the 16th day of the month. You can use the First Response Early Pregnancy Test any time of the day.
If you choose to test early and the result is negative, you may not be pregnant or it may be too early to tell because your urine does not have enough hCG for the test to give a positive result. If you do not get your period within seven days, you should retest with another First Response Early Pregnancy Test.
In clinical testing, First Response detected hormone levels consistent with pregnancy in 62% of pregnant women 5 days before their expected period, in 78% of pregnant women 4 days before their expected period, in 87% of pregnant women 3 days before their expected period and in 98% of pregnant women 2 days before their expected period.
