Positive (+) : Two red lines are visible. One is located in the test line region (T), the other is in control line region (C).And the line in test line region (T) is the same as or darker than the one in the control line region (C) It indicates probable ovulation in 24-48 hours.

Negative (-) : One or two red lines are visible. One is located in the test region (T), the other is in control region (C).And T line is lighter than the C line, or there was no T line. It indicates that no LH surge has been detected.
