Welcome to Merrion Fetal Health

This is my photo at 13w3d a Obewanaomi At 12wk ultrasound my dd nt measurement was reading between 2. After blood work came back my risk was 1: We had a fetal echo and it was all normal. At 36wks I had high amniotic fluid which a quick google search shows it’s linked to Down syndrome. At almost 39wks I had my second csection and had a genetically normal healthy baby girl who is now 8wks old. If you need to know for sure opt for amino as the quad screen and nipt are only giving you your odds. I spent so much time worrying if I was the “one” that I wished I trusted the nipt and enjoyed my pregnancy. I felt comfort in reading many posts on here and hope this can help others.

Pregnancy and Prenatal Tests

The extra chromosome causes physical differences, developmental delays and a tendency toward certain health problems. This condition is incurable, but testing during pregnancy gives parents the chance to prepare for the unique needs of a child with birth defects, as well as identifying any specific abnormalities that may require medical care after birth. Therefore you should carefully consider the advantages and disadvantages of screening test such as FTS compared with a diagnostic test such as CVS or amniocentesis.

The most accurate way of estimating the chances of your baby having a chromosomal problem is the first trimester screening test of the nuchal translucency measurement combined with a blood test. Nuchal Translucency screening is a non invasive test and poses no risk to you or your baby.

Jun 09,  · Nuchal fold scans in Ireland – info? Users: Threads: Hi I was public at CUMH and had the nuchal fold scan done at the 12 week dating scan. There was no charge but I did have to specifically request it (even though I was ). Hi I was public at CUMH and had the nuchal fold scan done at the 12 week dating scan. There was no charge but I.

The scan is usually done transabdominally, but occasionally it may be necessary to do the scan transvaginally: The purpose of the week scan: To date the pregnancy accurately. This is particularly relevant for women who cannot recall the date of their last period, have an irregular menstrual cycle, or who have conceived whilst breastfeeding or soon after stopping the pill. We measure the size of the fetus and from this we calculate the expected date of delivery.

To diagnose multiple pregnancy.

Dating scan

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. 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.

It is also used to check that the fetus size is within normal limits and record the location of the placenta.

Answers from experts on nuchal thickness at 12 weeks. First: The nuchal pregnancy test is reserved until.

It is usually part of an assessment called combined first trimester screening. Combined first trimester screening Combined first trimester screening assesses the risk for your baby having certain chromosomal abnormalities trisomy 13, 18 and This testing combines the nuchal translucency ultrasound with specific blood tests. Nuchal translucency ultrasound alone can also provide this risk assessment, but it is not as accurate as combined first trimester screening. Combined first trimester screening is a non-invasive way of assessing your risk, which means it does not involve putting needles into the placenta or amniotic sac, as happens with CVS and amniocentesis.

This means that combined first trimester screening simply tells us if your risk is low or high. For example, it tells us whether your baby has a low risk of having trisomy 13, 18 or 21, or whether your baby has a high risk of having trisomy 13, 18 or This test gives us an indication of whether we should worry about your baby based on these results. This means that combined first trimester screening will not give us a definitive answer.

Chorionic villus sampling and amniocentesis are invasive tests, involving putting needles into the placenta or amniotic sac, and they are associated with an increased risk of miscarriage. For more information of prenatal diagnostic testing, please go to:

Scans in the first trimester

During this scan the correct place of pregnancy is noted or otherwise Whether the pregnancy is intra- or extra- uterine. Ectopic pregnancy extra – uterine may be ruled out from 6 weeks onwards during this early dating ultrasound scan. The presence of fetal pole is checked as well as the pulsating fetal heart. This scan will also confirm the viability of early ongoing pregnancy especially in the presence of pain or bleeding or any other early pregnancy problems.

The baby’s length is measured from head to bottom Crown Rump Length up to 14 weeks.

Obstetric nuchal dating scan the screening test for down’s syndrome used at this stage of pregnancy is called obstetric nuchal scan nuchal dating scan the & involves dating scan at 8 weeks a blood test and measuring the fluid at the back.

Fetus should be examined in a mid-sagittal plane. Fetal neck should be in a neutral position. Fetal movement should be awaited to distinguish between amnion and overlying fetal skin, because, at this gestation, both structures appear as thin membranes. This is achieved by waiting for spontaneous fetal movement away from the amniotic membrane or by manually bouncing the fetus off the amnion.

Calipers should be placed on the inner borders of the nuchal fold. Calipers should be placed perpendicular to the fetal body axis. At least three NT measurements should be obtained, with the mean value of those used in risk assessment and patient counseling. Some authors recommend measuring the nuchal thickness twice and averaging the values 1 , while others advocate measuring it three times and using the largest value for risk assessment 2. Measure between 11 weeks and 14 weeks.

The minimum fetal crown—rump length should be 45mm and the maximum 84mm.

Frequently Asked Questions

Doppler Ultrasound The doppler shift principle has been used for a long time in fetal heart rate detectors. Further developments in doppler ultrasound technology in recent years have enabled a great expansion in its application in Obstetrics, particularly in the area of assessing and monitoring the well-being of the fetus, its progression in the face of intrauterine growth restriction, and the diagnosis of cardiac malformations.

Doppler ultrasound is presently most widely employed in the detection of fetal cardiac pulsations and pulsations in the various fetal blood vessels. The “Doptone” fetal pulse detector is a commonly used handheld device to detect fetal heartbeat using the same doppler principle. Blood flow characteristics in the fetal blood vessels can be assessed with Doppler ‘flow velocity waveforms’.

Anatomy Ultrasound scans are also known by other names like, Level II, dating, anomaly or targeted scan. A scan is performed at 18 to 20 weeks when the fetus is large enough for an accurate survey of the fetal anatomy, and when dates and growth can also be assessed.

What will you do with your scan photos? When will I have my dating scan? You’ll have a dating scan, also known as a week scan between about 10 weeks and 14 weeks of pregnancy. You’ll only have a scan before this, between six weeks and 10 weeks, if you’ve experienced bleeding , pain, or problems in a previous pregnancy Miscarriage Association nd. You’ll also be able to have an earlier scan if you’ve had recurrent miscarriages NICE How accurate are dating scans?

A dating scan is the best way to predict your due date PHE The point of the scan is to work out how many weeks pregnant you are. You may have calculated the length of your pregnancy from the first day of your last menstrual period LMP. However, conception doesn’t actually occur until around 14 days after your LMP, or later if your cycle is longer than 28 days Mongelli

Pregnancy by week

Below is a quick guide to some of the routine tests that are used in pregnancy. Home pregnancy tests HPTs only check for the hormone hCG; a hormone that is released by the cells of the fertilised ovum in pregnancy. A pregnancy will usually only continue after implantation if menstruation is prevented. Estrogen and Progesterone are produced by the Corpus Luteum and prevent menstruation by maintaining the lining of the uterus. The corpus luteum itself is maintained by hCG that is produced by the cells of the placenta after implantation of the fertilised ovum.

Normal hCG levels vary widely between different women and in different pregnancies for the same woman.

The due date. It is a blood test for down’s syndrome. Results 1 weeks 2. Find out more relationships than any one destination for dating scan also called the nuchal translucency scan is where dating scans.

Do I need a referral? Who can I bring to my pregnancy ultrasound? Pregnancy is an exciting time for couples, families and friends. We understand that your ultrasound is an opportunity to bond with your growing baby. You may wish to bring your partner or other support person to share in this special time. Young children, especially very young children, do not usually find ultrasounds entertaining or exciting.

They may even become distressed by being in a dark room with strangers examining their mother.
