4. The Annals of Pharmacotherapy

This review article compiles data from articles, textbooks and studies from the past 40 years to provide a comprehensive look at home ovulation prediction and pregnancy tests. Urine luteinizing hormone (LH) tests are found to be more accurate in detecting ovulation when compared to other fertility methods, such as following changes in basal body temperature or vaginal or cervical mucus, salivary ferning or calendar calculation. Though much of the information on LH tests is general, the Clearplan Easy Ovulation Kit, now Clearblue, is singled out for its high sensitivity to LH in consumer testing.

7. American Journal of Obstetrics and Gynecology

This study follows the menstrual cycles in 101 infertile women and compares the ability of basal body temperature (BBT), urine luteinizing hormone (LH) tests and blood tests for progesterone to detect ovulation. The standard used for detection of ovulation was transvaginal ultrasound and the urine LH kit used in this study was the Clearplan Ovulation test (now Clearblue). The LH peak occurred before ovulation as seen by ultrasound in all cases and 100 percent of the LH peaks occurred within three days of ovulation. Following the lowest point of BBT was a poor indicator of ovulation.

8. The Medical Journal of Australia

This scientific study compares the Clearplan, now Clearblue, Ovulation Test with basal body temperature (BBT) and cervical scoring for predicting ovulation. The accuracy of each method was determined by daily serum luteinizing hormone (LH) measurements. Clearplan was the most accurate at predicting ovulation, and in 96 percent of cases predicted ovulation within two days of the serum LH surge. Though this study is more than 20 years old, it is the foundation for the accuracy of the Clearplan, now Clearblue, Ovulation Test.
