Patient's question:
NoDoctor's answer:
24 to 48 hours before ovulation, luteinizing hormone (LH) in urine reaches its peak. Using an ovulation test strip for self-testing will show a positive result. Specific testing methods are usually provided on the packaging of ovulation test strips (it is essential to follow the instructions strictly to minimize errors). Unlike early pregnancy test strips, morning urine should not be used, and it is best to use urine samples collected at the same time each day. Two hours before collecting urine, water intake should be reduced, as diluted urine samples can also hinder the detection of the LH peak. If the menstrual cycle is regular, testing should be done three days before and three days after the expected ovulation time (14 days before the period), for a total of six consecutive days. If the menstrual cycle is irregular or abnormal, testing generally starts three days after the period ends.
