Others prefer to trust that their bodies and their babies will cope with the normal process of pregnancy and find these tests intrusive and anxiety producing. At one of your first pregnancy check-up visits, your LMC will give you a form to take to your local medical laboratory so you can have your blood and urine tested. If you have already had your blood tested before you Register with an LMC , you and your LMC can request that your doctor forwards a copy of the results instead of having these tests done again. Ultrasound is a form of non-ionising radiation. It has not been shown to be harmful to pregnant women or their growing babies, but neither has it been proven to be safe. Many research studies have shown that routine scanning of women whose pregnancies are progressing normally does not lead to healthier babies or fewer problems during labour and birth. Many parents find ultrasound scans reassuring and entertaining — however if you choose to have a scan you need to be prepared for the possibility that the information it reveals about your baby that may not be so reassuring. This involves a blood test that is taken when you are between 9 — 13 weeks pregnant that measures a couple of blood proteins and a Nuchal Translucency ultrasound scan when you are 11 — 14 weeks pregnant. You may be asked to pay a surcharge for this scan. The results of these test are combined with information about your age and weight to calculate the risk of your baby having Down Syndrome.
Dating scans, which are often performed around the seventh week of pregnancy, were one of those interventions she said needed questioning. As soon as a pregnancy test returns a positive result, most women are able to work out when their baby is due using one of the numerous due date calculators on the internet or with the help of their GP. Dating can be done at the nuchal translucency scan which can detect chromosomal abnormalities at about the twelfth week of pregnancy.
The other is an anatomy scan, where a lot of important developmental problems can be picked up, around 20 weeks. While a pregnant woman might be eager to see that flickering heartbeat and reassure herself all was well with her bub-to-be, Ms Eddy said they should instead be guided by the usual early pregnancy symptoms such as nausea, fatigue and having tender breasts. Rachael McEwing, a radiologist who is on the Maternity Ultrasound Advisory Group, said because unnecessary dating scans were being carried out, some women who really needed scans may not be able to get an appointment.
Ultrasound is a type of diagnostic medical imaging system which uses sound waves above the threshold of hearing to capture live images from within your body. It is painless and used in most soft tissue areas of the body. It is most well-known for its use in pregnancy. Your doctor, midwife or physio will refer you to have an ultrasound scan to help with the diagnosis of a condition or to assess your baby during pregnancy. A sonographer is a medical professional who performs the scan and a radiologist is a doctor who specialises in reporting the scan findings.
The report will go back to your referrer. Mercy Radiology also offers Ultrasound-Guided Procedures. You need a referral from your doctor, physio or midwife to be able to book an appointment for the scan. For early pregnancy, pelvic and kidney scans, your bladder needs to be full in order to optimally view your pelvic organs. The best way to achieve a full bladder is to first empty your bladder one and a half hours prior to your appointment.
How many scans to expect when you’re expecting
Routine ultrasound should not be offered or requested simply to confirm an ongoing early pregnancy in the absence of any clinical concerns, symptoms or specific indications. The purpose of the scan is to confirm viability, accurately establish gestational age, determine the number of viable fetuses, evaluate gross fetal anatomy and, if requested, assess the NT as part of the risk assessment for aneuploidy.
Document findings as per Early pregnancy ultrasound examination see above :. Once a live embryo is visible, the CRL should be used to calculate the due date. The MSD should not be included in this calculation.
When you first see your GP or LMC you will be asked to give a blood sample to test for: There are times in the pregnancy where an ultrasound scan may be.
Pregnancy these days can be a minefield of medical examination and testing, from the time you first do the home pregnancy test until the moment baby takes his or her first breath, and even after then. Most women accept the barrage of testing without question, feeling that the more information they can have, the better, whereas others opt out of some or all of them entirely.
Many people will also use this one to find out the sex of the baby. Facebook and other social media sites are often awash with images expectant parents put up to share their growing baby with the world. So with all this in mind, we must ask the question: how safe is ultrasound really? And how necessary? The vast majority of women will undergo at least one scan during pregnancy, generally aimed at ensuring the developing foetus is growing normally and is free from the myriad congenital abnormalities that can be viewed by sonography.
Generally the view is that the sooner you know about something, the easier it will be to treat and the better the outcome. However, there is also evidence that for all the good they can potentially do, ultrasounds could possibly be harmful to the growing fetus, being linked in recent years to various neurological problems, intra-uterine growth restriction, and other health problems, and the scans may not even make any significant difference to the outcomes for those infants in whom a congenital abnormality is detected.
Early Gender Reveal Ultrasound
Nuchal translucency is a measurement of fluid behind the baby’s neck that is present in all babies during the first trimester of pregnancy. Our staff are specially trained and audited through the Fetal Medicine Foundation to undertake this examination using very specific guidelines. Fortunately, these defects are rare.

You are pregnant and your Midwife or Doctor has suggested you have an ultrasound scan. You will have heard about ultrasound before, but may have some questions about ultrasound and your baby. This information is to help you with questions you may have. Ultrasound uses high frequency sound waves to see internal structures of the body.
A hand held ‘transducer’ sends a brief pulse of sound into the body. When this sound reaches an internal structure it sends back a little echo. These echoes are seen as the images on the monitor of the ultrasound machine. Diagnostic ultrasound has been used for over 40 years in pregnancy. Current knowledge indicates that the benefits of the prudent use of diagnostic ultrasound for pregnant women, far out-weigh theoretical risks. More than one scan may be requested by your Lead Maternity Carer for a number of reasons.
This may be to visualise an area not seen adequately on a previous scan; to check the baby’s growth; or to see where the placenta is located before delivery of the baby. The most common reason to have ultrasound in pregnancy is to determine the age gestation of the baby, to confirm its well being, and make sure the baby is growing normally. In early pregnancy , we determine the age of your baby by measuring the length of the embryo.
Jewellery, piercings or any other metal or plastic material should be removed before an X-Ray as it may be covering the area of examination: eg. You will be given a gown to wear. Opening Hours. Contact us.
Most women can instead have their first scan at 11 to 13 weeks — this is usually called the week scan. This scan can work out the due date and gestational age.
A dating scan may be performed from 6 weeks of pregnancy, with the optimal time being 8 weeks. It is used to confirm due dates, assess the viability of the pregnancy, check the number of embryos, provide maternal reassurance, and to rule out ectopic pregnancy fetus developing outside of the womb. Following the dating scan, a Nuchal Translucency NT scan is usually performed around Week 12 of pregnancy but can generally be done between 12 weeks 0 days to 13 weeks 6 days.
The NT scan is a screening test for early detection of Down Syndrome. Early fetal anatomy can also be assessed during this scan. Our sonographers are accredited to perform Nuchal Screening. Around week 20 of pregnancy, an Anatomy Scan is performed to rule out abnormalities that can be visualised with ultrasound imaging such as cleft lip, spina bifida, heart defects, and many other abnormalities.
It is also used to check that the fetus size is within normal limits and record the location of the placenta. The gender of the fetus can also usually be established during this scan. It is also used to assess the amount of amniotic fluid surrounding the baby and record the position of the placenta. We are pleased to offer the latest technology and offer 3D and 4D scanning to our patients.
What to do
After 12 weeks gestation, the age is confirmed from calculations using the head, abdomen and upper leg measurements. The ultrasound scan can also identify fetal abnormalities as well as twins. The time for your pregnancy ultrasound has arrived and we are pleased to join you on your journey providing quality scanning to support the best outcome for you and your baby. The person who does your scan is a Sonographer and there are several different types of scans they complete throughout your pregnancy.
During each scan we try to ensure your comfort although this can sometimes be challenging depending on the position of your baby.
The scan will confirm your due date and assess the viability of the pregnancy. The scan is most accurate around weeks. We can also scan you if you are.
Pregnancy Obstetric ultrasound examinations are carried out by a trained sonographer using an ultrasound machine. Sophisticated computer software and high frequency sound waves are used to gain an image by bouncing the waves into your body and back to the transducer held by the sonographer. Diagnostic ultrasound has been used for over 30 years.
Current scientific thinking indicates that there is no discernible detrimental effect on pregnant women or their babies. The potential benefits gained far out-weigh any possible risk. The Ministry of Health provides some funding for pregnancy ultrasound scans for those women meeting the criteria. This funding does not cover the full cost of providing the ultrasound. The most common reason to have ultrasound in early pregnancy is to ascertain the gestation age of the baby and to confirm its well-being viability.
In mid pregnancy ultrasound is used to visualize basic anatomical features of the baby. In late pregnancy the most common reason to have an ultrasound scan is to check foetal baby growth and well-being, or to check the position of the baby and the placenta prior to delivery. The scan can take anything from 10 minutes and involves lying on a couch. The transducer is gently rubbed over your skin.
Warm gel is used as a coupling agent and allows the smooth transmission of the sound waves into and out of your body.
