All results must be read in 5-10 minutes when the dye clears and you see a clear white background.

LH negative: Only the control line appears, or both lines appear, but the test line is lighter than the control line.

LH positive: If two lines are visible, and the test line is as dark or darker than the control line, you are likely to ovulate within the next 24-48 hours.

LH peak: To determine your LH peak day, compare all your LH tests from that cycle. The last darkest result is considered your LH peak. Even if none of your strips have a test line darker than the control line, you can still figure out your LH peak day by comparing all your tests and picking out the darkest one.

Invalid: No visible lines at all or there is only a T line. Repeat with a new test kit. If the test still fails, please contact customer support with a detailed description of the issue and the test pictures by tapping the Support tab in the app.
