Determination of the ovulation time, the most probable time to become pregnant.

LH Check-1 test (ref. 5003) is used for semi-quantitative detection of the urinary LH surge.

Before ovulation, the urinary LH level is very low but it rises rapidly 24-36 hours before ovulation.

The most probable time to become pregnant is 2-3 days after the LH surge.

LH self testing devices (strip, cassette and midstream formats) areCE marked since July 2005.
