The Instant-View® LH Ovulation Predicting Test is a qualitative immunoassay for the detection of human Luteinizing Hormone (hLH) in human urine to predict the occurrence of ovulation. Ovulation is regulated by the elevation of human luteinizing hormone (hLH). Usually, around 14 days before the period starts, hLH has a brief, significant rapid increase called the "LH surge". The hLH surge triggers the release of an egg or egss for the ovary. Statistics have shown that conception is most likely to occur within 36 hours following the LH surge. Therefore, the hLH surge is an ideal indicator for predicting ovulation. The Instant-View® LH Ovulation Predictin test provides a qualitative screening result and is for healthcare professional use only and not for self-testing. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result. The test is available in cassette and dip strip format.
