The main purpose of a dating scan is to check the stage of pregnancy and therefore when the baby is due. Measuring the baby can be more accurate than dating by the last menstrual period. It is also an opportunity to check the baby is alive and developing as expected, and check for twins. This scan may also be part of your screening test for Down's syndrome nuchal translucency scan. Occasionally, if the baby is in an awkward position, an internal scan may be carried out, using a vaginal probe.
