Instead, you will be offered another blood test between 14 and 20 weeks of pregnancy to screen for the risk of Down's syndrome. This test is not quite as accurate as the combined test.

This can usually be seen clearly on a scan, and will be detected in around 9 out of 10 babies who have this problem. Some other problems, such as heart defects, are more difficult to see. The scan will find about half 5 out of 10 of babies who have heart defects. In some very serious, rare cases where no treatment is possible, the baby will die soon after it's born or may die during pregnancy. Most scans are carried out by specially trained staff called sonographers.
The scan is carried out in a dimly lit room so the sonographer can get good images of the baby. You'll be asked to lie on a couch, lower your skirt or trousers to your hips and lift your top to your chest so your abdomen is uncovered. The sonographer or their assistant will tuck tissue paper around your clothing to protect it from the gel, which will be put on your tummy. The sonographer then passes a handheld probe over your skin to examine the baby's body. The gel makes sure there's good contact between the probe and your skin. A black and white image of the baby will appear on the ultrasound screen.

Having the scan doesn't hurt, but the sonographer may need to apply slight pressure to get the best views of the baby. This might be uncomfortable. The sonographer needs to keep the screen in a position that gives them a good view of the baby. The screen may be directly facing them, or at an angle. But they'll be able to talk to you about the pictures once they've completed the check. Sometimes it's difficult to get a good picture if the baby is lying in an awkward position or moving around a lot, or if you're above average weight or your body tissue is dense. This doesn't mean there's anything to worry about.
You may need to have a full bladder when you come for the appointment. The doctor or midwife looking after you will let you know before you come. If you're not sure, you can contact them and ask.

Tests, scans and checks
However, the sonographer may not be able to get good views if your baby is lying in an awkward position or moving around a lot. If it's difficult to get a good image, the scan may take longer or have to be repeated at another time. There are no known risks to the baby or the mother from having an ultrasound scan, but it is important that you consider carefully whether to have the scan or not.
This is because the scan can provide information that may mean you have to make further important decisions. For example, you may be offered further tests, such as amniocentesis, that have a risk of miscarriage. Hospitals in England offer all pregnant women at least 2 ultrasound scans during their pregnancy:. The first scan is sometimes called the dating scan. The sonographer estimates when your baby is due the estimated date of delivery, or EDD based on the baby's measurements.
The dating scan can include a nuchal translucency NT scan, which is part of the combined screening test for Down's syndrome , if you choose to have this screening. This scan checks for structural abnormalities anomalies in the baby. Some women may be offered more than two scans, depending on their health and their pregnancy. No, not if you don't want to. The dating scan and anomaly scan are offered to all women, but you don't have to accept them. Your choice will be respected if you decide not to have the scans, and your antenatal care will continue as normal.
You'll be given the chance to discuss it with your maternity team before making your decision. Most hospitals do not allow children to attend scans as childcare is not usually available.

Please ask your hospital about this before your appointment. Remember, an ultrasound scan is an important medical examination and it is treated in the same way as any other hospital investigation. Ultrasound scans can sometimes find problems with the baby. Most scans show that the baby is developing normally and no problems are found.
