Luteinizing hormone (LH) is always present in your urine and increases just before you ovulate. First Response Ovulation Tests are used to detect this increase or surge in LH, which precedes ovulation by 24 to 36 hours. Your two most fertile days begin with the LH surge, meaning if you have intercourse during this time frame, your chances of becoming pregnant will increase.

It is easy to use: Simply place the absorbent tip in your urine stream for five seconds. The purple color moving across the clear top indicates that the test is working. If two purple lines appear, you have reached your LH surge; one line is a no go. Detailed instructions will help you determine when you should begin testing.
