LH concentration in urine is usually sharp rise in 36-48 hours before ovulation, peaks in 14-28 hours. The amount of LH in the urine usually rised sharply around 36 to 48 hours before ovulation, and reached the peak at 14~28 hours, the follicular membrane ruptured at about 14 to 28 hours after the peak and discharged the mature eggs. Women are most fertile in the LH peak within 1-3 days, therefore, detection of LH in urine can be used to predict ovulation time[1]. This kit based on colloidal gold immune chromatography analysis technology for the qualitative detection of LH antigen in human urine samples, which can give a result within 15 minutes.
