One Step LH Urine Ovulation Test is quick, accurate, and easy-to-use. Ovulation Predictor Kit (OPK) is a qualitative test that predicts LH surge (Luteinizing Hormone), which provides useful information for individuals who are trying to conceive (TTC). Luteinizing Hormone is a hormone released by the pituitary gland, a small gland at the base of the brain. The hormone stimulates the ovaries to produce and release eggs each month during the menstrual cycle. The level of LH in the blood and urine is highest before ovulation. This increase in hormone level is sometimes called a "surge". If fertility drugs are given to stimulate ovulation, an LH test can help determine the best time for sexual intercourse. The LH test may also be used to determine when eggs are mature enough to be surgically removed from the ovary as part of the in vitro fertilization process. LH tests may also aid in the diagnoses of polycystic ovary disease, premature ovarian failure, and menopause.

The tests detect LH in urine in a qualitative format with sensitivity of 25mIU/mL (International Standard Value) and specificity is 99.8%. Tests have an expiry date of 2 years and can be stored in a dry environment ranging from 2 to 30 degrees Celsius. Results are available in just minutes.
