has a brief review of the roles of LH in supporting follicular development and function
of LH Ovulation Rapid Test Cassette in preparing pregnancy.
A rapid increase in LH plasma, called an LH surge, induces ovulation within 2-3 days.
The surge can be detected by the observation of LH in serum or urine with ovulation
predictor kits (OPKs). If a woman knows the duration of her menstrual cycle, she can
plan the timing of testing. The average length of the menstrual cycle is 28 days, but a
