Why can I test earlier with First Response Pregnancy Test than with any other pregnancy test?
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 6 days before their expected period. Therefore, you can use the First Response Early Pregnancy Test as early as 6 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 17th day of the month.
The amount of pregnancy hormone increases as pregnancy progresses. In clinical testing, First Response detected hormone levels consistent with pregnancy in 62% of women 5 days before their expected period, in 78% of women 4 days before their expected period, in 87% of women 3 days before their expected period and in 98% of women 2 days before their expected period. Note that hormone levels may vary.
