Why should you not use first morning urine for ovulation test?

The ovulation predictor test looks for a hormone called LH or luteinizing hormone in your urine. LH hormone surges 24 to 36 hours before you ovulate. If the surge occurs first thing in the morning, it can take 4 hours for the hormone to be detected, so your first morning urine may miss it.
