LH Ovulation Rapid Test Devices

LH Urine Midstream

One Step LH Ovulation Rapid Test kits, including LH rapid test strip, LH urine cassette and LH test midstream, are based on the chromatographic immunoassay principle, and are used to qualitatively predict the LH surge. The testing results are mainly used to predict the LH surge, and also can be used to as an indicator of certain dysfunctions. Rapid LH tests are to be tested with human urine, so these testing kits belong to In-vitro diagnostic (IVD) test devices.

Luteinizing hormone is always present in human urine. LH increases dramatically just before a woman's most fertile day of the month in a process commonly referred to as the "LH Surge." This LH increase triggers ovulation, the process during which an egg is released from a woman's ovary. Because the egg can only be fertilized between 6 to 24 hours after ovulation, detecting ovulation in advance by testing for the LH surge is very important for women seeking pregnancy.

The best times to test are between 11:00 am to 3:00 pm and between 5:00 pm to 10:00 pm. Early morning testing is not recommended as LH does not appear in the urine until later in the day. To ensure that you do not miss your surge, you may test twice a day, once in the earlier time frame and once in the later time frame. The detection limit for the LH Test Kit is 30 mIU/ml LH. Urine samples with LH concentrations of 30 mIU/ml or greater will induce a positive result.

When testing with a LH Ovulation rapid test device, the first thing to do is to determine the length of the menstrual cycle. This is the number of days from the first day of the menstrual bleeding to the day before the next bleeding begins again. If the cycle is shorter than 21 days or longer than 38 days, consult with a doctor one when to start using the test kit within a menstrual cycle. Or else, when not knowing the cycle length, one can also begin the test 11 days after the first period, since the average menstrual cycle length is 28 days. Perform one check each day over a 5-day period, or until the LH surge is detected.

Background Information

LH Test kits

During the reproductive years, typical LH levels are between 1-20 IU/L. High LH levels can be detected during the LH surge, which typically last 48 hours. The testing of the LH surge can be used to predict the impending of ovulation. A rapid LH urine test kit is the most commonly used urinary ovulation predictor kits, which are performed, typically daily, around the time ovulation are expected. The conversion from a negative to a positive reading suggests that ovulation is about to occur within 24-48 hours. That means the LH rapid test kits can be used to monitor the ovulation cycle, and this information is helpful to couples who are trying to conceive. But because sperms can stay viable in the woman's body for several days, LH tests are NOT suitable as a contraceptive measures, as the LH surge typically occurs after the beginning of the fertile window.
