The VoxPress LH Ovulation Rapid Test Cassette is a rapid one step assay designed for qualitative detection of human luteinizing hormone (LH) in urine to predict time of ovulation. For self-testing and in vitro diagnostic use only First morning urine is not recommended, but any other time of day is suitable. For best results, try to collect urine at approximately the same time between 10:00 A.M. and 8:00 P.M. each day. The urine specimen must be collected in a clean, dry container either plastic or glass. Luteinizing hormone (LH) in elevated quantities causes ovulation (the release of the egg from the ovarian follicle). Throughout the menstrual cycle, a small amount of LH is produced, but during the middle of the cycle LH briefly and dramatically increases. This increase is called the “LH surge” and precedes ovulation. Conception is most likely to occur within 24 to 48 hours following the LH surge. The LH Ovulation Rapid Test Cassette is specifically designed to detect your LH surge - the time when you are likely to ovulate. If you receive a positive on an LH test, you are in your most fertile phase of your menstrual cycle. The test reagent is exposed to urine, allowing urine to migrate through the absorbent test strip. The labelled antibody-dye conjugate binds to the LH in the specimen forming an antibody-antigen complex. This complex binds to the anti-LH antibody in the test region (T) and produces a color line. In the absence of LH, there is no color line in the test region (T). The reaction mixture continues flowing through the absorbent device past the test region (T) and control region (C). Unbound conjugate binds to the reagents in the control region (C), producing a color line, demonstrating that the test cassette is functioning correctly. The test cassette can accurately detect your LH surge when the concentration of LH is equal to or greater than 25mIU/ml.
