Do I need to compare my daily OVRY™ Ovulation Test Strip results to detect the LH surge?

Comparing your daily test results is not necessary but it can help you assess whether the test line is the same color or darker than the control line which indicates a positive result. One way to do this is to take a photo of the test strip as soon as your test results are ready to be read. If you repeat this with each test, it will be very noticeable when the LH surge occurs since an LH surge will produce the darkest test line. Please note: if you do compare daily results, only take the photos when the tests are within the appropriate time windows for interpreting results and ensure that the lighting is the same every time a strip is photographed.
