What is the purpose of a luteinizing hormone test?
The LH test is frequently used to determine the timing of ovulation. Couples who are trying to become pregnant may use information about the timing of ovulation to improve their chance of conception. The LH test and other hormone tests may be used during infertility screening to chart a woman’s menstrual cycle. It may also be used during preparation for in vitro fertilization, to determine when eggs are mature and ready to be removed from the ovary. Source: The Gale Group.
