Additional Information

Official title Generic Protocol for the Collection of Early Pregnancy Urines
Description In order to develop and validate new and existing products SPD needs to maintain a sample bank of early pregnancy urine samples from the beginning of the cycle in which pregnancy is achieved, and throughout pregnancy. This generic study will be initiated to maintain the SPD sample bank, the study will run continuous to replenish the sample bank, as samples are used. To obtain these samples, volunteers wishing to become pregnant will be offered the use of a Clearblue ovulation prediction product to enable them to pinpoint their most fertile time and aid conception. Whilst on the study volunteers will be asked to collect daily urine samples and return them to SPD on a regular basis in addition to keeping a daily record of menstrual cycle details and test results. Women who become pregnant during the course of the study will be asked to continue collecting daily urine samples for a minimum of a further 4 weeks. Each volunteer will be on the study for a minimum of 1 and a maximum of 3 cycles. Volunteers will not be allowed to re-enter the study once they have completed without achieving pregnancy It is anticipated that any one of SPD's marketed ovulation prediction products may be used in this study to aid the conception rate, this may include, but not be limited to the Clearblue fertility monitor and Clearblue digital ovulation test. It is anticipated SPD will have to recruit approximately 600 volunteers to achieve each 100 pregnancies and that approximately 500 volunteers will be participating at any one time. The study size may be increased or decreased to meet sample demands.
