Project-0027. Lay User Usage Study
Study Details
Study Description
Brief Summary
Study volunteers will be required to conduct a home pregnancy test (HPT) at the trial centre and provide a sample of urine from the same void for further testing.
Volunteers will then complete a product usage questionnaire and leaflet comprehension questionnaire at site.
Follow-up information will be required from all volunteers as both additional urine sample(s) and pregnancy information to establish true pregnancy status at the study visit.

Detailed Description
Eligible volunteers will be recruited into the study and provide informed consent. Volunteers will then test their urine sample with the investigational HPT according to the device Instructions for use and record their result onto the results sheet. A sample of urine from the same void will be obtained for further testing by the study technicians.
The technician will then test the volunteer's sample with a second investigational HPT, a professional use pregnancy test and a Clearblue Digital HPT, the results of which will be used to provide the volunteer with her pregnancy test result. During technician testing, the volunteer will complete the device usability and leaflet comprehension questionnaires.
At the end of the study visit, all volunteers will be provided with materials to allow follow-up for the determination of pregnancy status.
The majority of volunteers will be requested to provide one additional urine sample, collected 2 days after the study visit. If early pregnancy is suspected the volunteer will be requested to provide an additional 7 daily urine samples following the study visit. All volunteers will be required to provide details of pregnancy status (documented menses or pregnancy confirmation by health care professional) after the study visit.
True pregnancy status will be determined by laboratory tests and clinical information. The study will continue until a minimum of 300 pregnant and 300 not pregnant volunteers have completed the study.

The estimated sensitivity and specificity of the investigational HPT
- Calculation of the level of certainty a user can have if the device gives a pregnant (positive predictive value (PPV)) or not pregnant result (Negative predictive value(NPV)). [3 months]
The estimated NPV and PPV of the investigational HPT
- Number of participants correctly answering questions about the product when referencing the instructions for use (IFU) leaflet. [3 months]
Volunteer leaflet comprehension of the IFU
- Participants opinion on using the product. [3 months]
Volunteer usability of the IFU
