Understand your baby's risk profile
Screening tests provide a clear, personalised risk estimate for common chromosomal conditions, helping you decide if further diagnostic testing is right for you.
Prenatal screening includes a range of non‑invasive tests that assess the likelihood of your baby having certain chromosomal conditions or birth defects. These tests are safe for you and your baby – they provide important information without posing any risk to the pregnancy.
Screening is not the same as diagnosis. It helps identify pregnancies that may benefit from further diagnostic testing (such as chorionic villus sampling or amniocentesis) or from extra monitoring during pregnancy. Most women receive a low‑risk result, which offers strong reassurance. For those with a higher‑risk result, prenatal screening opens the door to informed decisions and early preparation.
At Amytri, we offer a full spectrum of prenatal screening options – from first‑trimester combined screening (NT/NB + blood markers) to non‑invasive prenatal testing (NIPT) and second‑trimester maternal serum screening. Our consultant radiologist and fetal medicine specialist will guide you through the options, explain the benefits and limitations of each, and help you choose the pathway that feels right for you.
Prenatal screening gives you time – time to learn, to plan, and to seek the best care for your baby.
Screening tests provide a clear, personalised risk estimate for common chromosomal conditions, helping you decide if further diagnostic testing is right for you.
Whether you choose to have no further tests, opt for NIPT, or proceed with CVS/amniocentesis – screening gives you the information you need to make decisions that align with your values.
For the majority of women, screening returns a low‑risk result – offering deep reassurance that the baby is unlikely to be affected by the conditions screened for.
We offer a range of screening tests – from traditional combined screening to advanced NIPT – so you can select the level of information that feels right for you.
NT/NB scan (11–14 weeks) combined with maternal blood markers (PAPP‑A and free β‑hCG) to assess risk for Down, Edwards, and Patau syndromes. Detection rate ~85‑90%.
A simple maternal blood test from 10 weeks that analyses fetal DNA in your blood. Highly accurate (>99%) for trisomies 21, 18, and 13, and also screens for sex chromosome anomalies. No risk to the pregnancy.
Blood test between 15 and 20 weeks measuring four markers (AFP, hCG, uE3, inhibin‑A) to screen for Down syndrome, Edwards syndrome, and open neural tube defects.
Also known as the "level II" or "TIFFA" scan – a comprehensive anatomical survey that screens for structural abnormalities, not just chromosomal conditions.
For the most comprehensive risk assessment, we can combine multiple screening tests – e.g., first‑trimester screening plus NIPT – to give you a very high degree of confidence.
Every woman's situation is unique. We offer one‑on‑one consultations to explain the options, discuss the pros and cons, and help you choose the screening pathway that makes sense for you.
We meet with you to review your medical history, preferences, and timing – and recommend the most appropriate screening test(s).
We coordinate your ultrasound appointment and blood draw (if needed) at the optimal gestational age for each test.
Your ultrasound is performed by our specialist, and blood samples are taken with care – both are safe and painless.
We review your results with you, explain the risk estimate, and discuss any further steps – diagnostic testing, extra monitoring, or simply reassurance.
Most women choose at least one form of prenatal screening. It's a personal decision, and we respect your choice either way.
Advanced maternal age increases the risk of chromosomal anomalies – screening can provide a personalised risk estimate.
If you've had a previous pregnancy affected by Down syndrome or another trisomy, early screening is especially important.
If you or your partner carry a genetic condition, screening can help assess the risk to your baby.
If any ultrasound marker raises concern, screening can help clarify the overall risk.
Twins or triplets require special interpretation – we guide you through the nuances.
Many women choose screening simply to reassure themselves that their baby is developing as expected. That's a perfectly valid reason.
Our consultant radiologist is experienced in all forms of prenatal screening – from ultrasound to NIPT interpretation. We stay up‑to‑date with the latest evidence and guidelines, ensuring you receive accurate, reliable information. Most importantly, we communicate clearly and compassionately, so you feel supported whatever the result.
Decisions about screening and testing are often best made together. We encourage partners to attend consultations and scan appointments – so both of you can hear the information, ask questions, and share the emotional experience.
Whether you're choosing NIPT, having a scan, or discussing results, you don't have to do it alone. We create a supportive space for both of you.
Prenatal screening includes a range of non‑invasive tests (ultrasound and blood tests) that estimate the risk of your baby having certain chromosomal conditions, such as Down syndrome, or structural abnormalities. It does not diagnose – it provides a risk estimate.
Screening gives a risk estimate – it tells you the likelihood of a condition. Diagnostic tests (CVS or amniocentesis) give a definitive answer but carry a small risk of miscarriage. Screening helps you decide if you want diagnostic testing.
NIPT (Non‑Invasive Prenatal Testing) is a blood test from 10 weeks that analyses fetal DNA circulating in your blood. It is very accurate (>99%) for trisomies 21, 18, and 13, and is completely safe for the pregnancy.
No – you can choose which tests to have. We recommend a discussion with your doctor to decide what suits your situation and preferences. Some women choose NIPT only, others prefer combined screening, and some choose no screening at all.
Screening tests are not 100% accurate – they can give false positives or false negatives. However, combining tests improves accuracy. We always explain the detection rate and false‑positive rate so you can make an informed decision.
A high‑risk result doesn't mean the baby has a condition – it means the risk is higher than the background risk. We will discuss your options, which may include NIPT (if not already done) or invasive diagnostic testing to get a definitive answer.
