What happens on your first 12 week scan?

It involves a blood test and measuring the fluid at the back of the babys neck (nuchal translucency) with an ultrasound scan. This is sometimes called a nuchal translucency scan. The nuchal translucency measurement can be taken during the dating scan.

How accurate is the 12 week dating scan?

The earlier the ultrasound is done, the more accurate it is at estimating the babys due date. Ultrasounds performed during the first 12 weeks of pregnancy are generally within 3 - 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation.

Can you eat before 12 week scan?

Empty your bladder 90 minutes before exam time, then consume one 8-ounce glasses of fluid (water, milk, coffee, etc.) about an hour before exam time. We recommend a two-piece outfit so we can access your abdomen without you removing your clothing. You may eat normally prior to having a fetal ultrasound.

Do I need to drink before 12 week scan?

You will be asked to drink about two pints of water before the scan to fill up your bladder; this pushes up the uterus to give a clearer picture. Youll then have gel rubbed onto your belly and a hand-held scanner passed smoothly backwards and forwards over your skin.
