First Response 1-Step Ovulation Predictor Test is an easy way to find
the 2 days when you are most able to become pregnant. It quickly and
accurately detects the increase in luteinizing hormone (LH surge),
which normally occurs 24-36 hours before ovulation. Your most fertile
2 days begin with the LH surge. You are most likely to become pregnant
if you have intercourse within 24-36 hours after you detect your LH
surge.
Easy to use - one simple step
Over 98% accurate in laboratory studies
Clear results in just 5 minutes
Convenient - test any time of day
The presence of 2 similar purple lines means you have detected your LH Surge. The test line may be darker than the reference line. This mean that your 2 most fertile days of the month have started. The presence of 1 line or 2 lines with the test line lighter than the reference line indicates that you have not yet reached your LH Surge.
