Clearblue Easy Ovulation Test Pack

Pros
  • Easy to use
  • Immediate results
  • More sensitive than most
Cons
  • Results can be hard to interpret
  • Expensive
  • Irregular menstrual cycles may require more testing

Scientific studies indicate that urine luteinizing hormone (LH) tests are accurate at predicting ovulation, and the most often tested and recommended test strip is the Clearblue Easy Ovulation Test. The Clearblue test is the most sensitive available, able to detect down to 22 mIU/ml of LH, allowing it to reliably predict ovulation for nearly nine out of 10 women, studies say. Reviewers say the test is easy to use and gives results immediately. However, interpreting the results can be difficult, as you have to compare the result and control lines to see which one is darker. If you prefer the results to be spelled out for you, reviewers say you'll appreciate the Clearblue Easy Digital Ovulation Test (Est. $36 for 20). In addition, like all urine LH tests, the Clearblue Easy Ovulation Test can predict only the two most fertile days of a woman's cycle, unlike the Clearblue Easy Fertility Monitor (*Est. $170), which can predict up to six fertile days.

Scientific reviews from the Annals of Pharmacotherapy and the American Journal of Health-System Pharmacy provide comprehensive reviews of ovulation tests and fertility monitors and detailed information on the Clearblue Easy Ovulation Test. Obstetrics and Gynecology, The Medical Journal of Australia and Fertility and Sterility provide scientific research backing the accuracy and reliability of urine LH tests in general and the Clearblue Easy Ovulation Test in particular. ConsumerReports.org offers one of the most thorough reviews of the Clearblue Easy Ovulation Test, with extensive testing of and comparison to 11 other ovulation tests. User reviews at Diapers.com and Drugstore.com shed insight into real-world experiences with the test.

1. 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 by calendar calculation. Though much of the information on LH tests is generalized, the Clearplan Easy Ovulation Kit, now Clearblue, is singled out for its high sensitivity to LH in consumer testing.

2. Medscape.com

This in-depth clinical review describes various ovulation testing methods and how they work. The benefits and limitations of each are listed, as well as the results of several medical studies. Urine LH tests are reviewed in general, though the Clearblue Easy is noted to be the most sensitive at 22 mIU/ml per a previous study.

4. 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.

5. 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.
