Do currently available at home pregnancy tests (HPTs) meet their claimed sensitivity for hCG in early pregnancy testing?
These are the first urinary reproductive hormone normograms referenced to the actual day of ovulation, and therefore provide the most robust reference ranges to examine menstrual cycle endocrinology.
This research aims to determine the best objective method for defining the LH surge.

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.
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.
