Our female ovulation test paper contains PVC patch, absorbent paper, and handle paper. It can help users determine the best time to ovulate by detecting LH levels in the body. It is very simple to use: just immerse the absorbent end of the test strip into the urine sample for 5 seconds, and wait for the results to be displayed within 5 minutes. Read the results: If the T-line is darker than the C-line, it means your LH level surges, and you are likely to ovulate within 24-48 hours, which is the ideal time to prepare for pregnancy. If the T-line is lighter than the C-line, it means your LH level has not reached its peak ovulation, and ovulation is unlikely to occur at this time; if the C-line has no color, it means that the test is invalid, please retest and you can understand the ovulation period, which helps increase the chance of conception and optimize the conception preparation strategy.
