Home urinary luteinizing hormone immunoassays: clinical applications

Abstract

Home ovulation prediction kits represent a valuable advance in monoclonal antibody technology and offer patients a quick, reliable, and relatively inexpensive means to predict the day of ovulation. These kits are used widely by patients trying to conceive and are commonly recommended by physicians involved in the care of infertile couples. They provide a more accurate and practical means to prospectively predict the time of ovulation than do BBT graphs or cervical mucus exams, and can be used as presumptive evidence of ovulation. Whereas ovulation prediction kits appear to be most useful for couples in timing sexual intercourse, other possible uses exist, including timing of AI, the PCT, and the endometrial biopsy for luteal phase evaluation. Despite multiple potential applications, clinical studies which support the use of urinary LH immunoassays in the evaluation and treatment of the infertile couple are quite limited. More well-designed studies to define the clinical value of ovulation prediction kits need to be undertaken.
