About this study

The Clearblue Advanced Ovulation Test is designed for home use by women who are trying to get pregnant now or in the near future. It identifies those days in a woman's cycle on which intercourse is most likely to lead to conception.

The product defines three phases of fertility through urine hormone measurement: Low (small chance of conceiving), High (increased chance of conceiving) which is achieved by the detection of a rise in the level of estrone-3-glucuronide and Peak (highest chance of conceiving) which provides an early warning of impending ovulation through detection of the luteinising hormone surge which precedes it by 24 - 36 hours.

This protocol aims to demonstrate the successful usage of the Clearblue Advanced Ovulation Test product by lay-users in the intended environment.

Elements of system usability, product satisfaction and ease of use will be used to assess overall product performance in lay-user hands.

Lay users will be required to user the product according to the instructions for use for a mimimum of 1 complete menstrual cycle after which they will be required to provide feedback on product use.

A usability scale which focusses on providing subjective feedback from users. This is a simple ten-item attitude Likert scale which each volunteer will complete after 4 weeks of product use. The primary endpoints of this study will focus on the use of this scoring scale to determine the usability of the product in lay-user hands.
