The first stage is performed in the first trimester, no earlier than 11 weeks and two days of pregnancy and up to 13 weeks gestation, as determined by the first day of your last menstrual period or a previous dating scan.Prompt diagnosis made possible by transvaginal ultrasound can, therefore, result in earlier treatment.It is recommended that all pregnant women have a scan in the first trimester, to establish the date when the baby is due, check the number of babies also the position of the placenta.For copies of the Integrated Test information leaflets please click on the links below.
