Impact of digital home ovulation test usage on stress, psychological wellbeing and quality of life during evaluation of subfertility: a randomised controlled trial
This randomised, controlled trial examined use of Ovulation Tests on self-reported levels of stress, psychological wellbeing and quality of life, and biochemical measures of stress, in new attendees at a fertility clinic.
Comparison of home pregnancy test with weeks estimator and ultrasound crown rump measurement to predict delivery date
The objective of this study was to compare prediction of final delivery date by Clearblue Advanced Pregnancy Test in comparison to ultrasound.
Demographic trends, such as later motherhood and reduced family size, indicate that the ways women consider fertility and becoming pregnant may also be changing. This study sought to understand women’s views and understanding of fertility and conception in five divergent countries
Comparative study of home ovulation tests, including new dual-hormone test, to reference day of LH surge
This study aimed to compare the accuracy of six home ovulation tests in detecting the LH surge and the number of days of fertility identified by each test.
Basic understanding of reproductive health is of value to women before they start a family. However, there is little published information on how knowledgeable women are regarding fertility and pregnancy and their attitudes towards these topics. This study examined women’s knowledge, how they prepared for pregnancy and where they sourced their information.
Analytical Performance of Home Pregnancy test that estimates time since ovulation based on hCG threshold concentration at week boundaries
The objective of these studies was to evaluate the analytical performance of the Clearblue Advanced Pregnancy Test with Weeks Estimator/Conception Indicator device.
Clinical analytical tests are now often being marketed to untrained people, in formats normally only used in the laboratory environment. For example, although many home pregnancy tests are designed to be used by women with no training, direct copies of laboratory tests in strip and cassette formats are also available. The objective of this randomised study was to determine whether these types of tests could be used accurately by a lay person, in comparison to tests specifically designed for home use.
The daily levels of early hCG could provide information on pregnancy progression; however, most published studies suffer from using last menstrual period (LMP) as the reference for dating of pregnancy, leading to broad value ranges. We studied daily urinary hCG levels stratified by two accurate references for pregnancy duration; first trimester Crown Rump Length (CRL) measurement and luteinizing hormone (LH) surge as a marker for ovulation, and LMP.
