Prenatal screening · From 10 weeks + 4 days · London & St Albans
Private NIPT Test & Early Pregnancy Scan
£549 for standard NIPT blood screening and an early pregnancy ultrasound. NIPT estimates the chance of Down’s syndrome (T21), Edwards’ syndrome (T18) and Patau’s syndrome (T13). It uses a blood sample from your arm. The scan assesses early pregnancy development, gestational age and whether one or more babies are visible.
NIPT is a screening test, not a diagnosis. A higher-chance result needs discussion with your maternity team; a lower-chance result cannot rule out every condition. Screening is optional, and you can choose not to have it.

Questions before deciding? Call reception to discuss the appointment and arrange clinical advice.
Your screening, your choice
Some people want information about the chance of these conditions; others prefer not to have screening. You can take time to decide, ask questions and decline NIPT or later testing. Your choice should be respected.
Before you decide
Consider what information you want, how you might use it, and how you would feel about uncertain results or further tests. The conditions screened for affect people differently; screening cannot predict a child’s individual needs or quality of life.
Continue maternity care
Keep your routine NHS or private maternity appointments and recommended scans. This service does not replace routine antenatal screening or the fetal anomaly scan.
Independent information
Antenatal Results and Choices (ARC) provides independent information and support before, during and after antenatal screening. You can also discuss your choices with your midwife or maternity team.
What the test and scan assess
NIPT blood screening
The standard panel estimates the chance of trisomies 21, 18 and 13. Cell-free DNA is analysed from your blood; the pregnancy-related DNA mainly originates in the placenta. The test does not check for every genetic condition.
Early pregnancy ultrasound
The sonographer assesses early pregnancy development, heartbeat where visible, measurements and the number of babies. Sometimes findings are uncertain and another scan or clinical assessment is needed. An early scan cannot confirm that every aspect of development is normal.
Optional fetal-sex information
Tell the team if you want fetal-sex reporting included or excluded. It is included on request where available and suitable for the pregnancy. Laboratory and multiple-pregnancy limitations may affect what can be reported.
Different tests answer different questions. NIPT does not assess structural anatomy. Continue the recommended fetal anomaly scan and antenatal pathway even after a lower-chance NIPT result.
Understanding reliability and limitations
No screening result is certain. Performance depends on the condition, the test method and the pregnancy. Ask for the current patient information for the laboratory test being supplied.
Detection rate / sensitivity
Among pregnancies affected by a particular condition, this describes how often the test returns a higher-chance result. It does not tell you the chance that your own higher-chance result is correct.
Positive predictive value (PPV)
Among higher-chance results for a condition, this describes the proportion confirmed to be affected. PPV varies with the condition and underlying chance. It is different from the detection rate.
False-positive and false-negative results
A false-positive result is higher chance when the pregnancy is unaffected by that condition. A false-negative result is lower chance when it is affected. The false-positive rate is calculated among unaffected pregnancies, not among all higher-chance results.
A higher-chance result is not a diagnosis; a lower-chance result is not a guarantee. Discuss any result alongside your scan findings, history and other screening information.
What happens after your result?
Lower chance
The chance of the screened condition is reduced, but is not zero. Continue your maternity care and recommended scans. Contact your maternity team about any new concerns.
Higher chance
Discuss the result with your maternity or fetal medicine team. They can explain diagnostic options such as CVS or amniocentesis and their benefits and risks. NIPT alone cannot establish a diagnosis. You may choose further testing or no further testing.
No result / inconclusive
The laboratory may be unable to report a result for technical or biological reasons, including low placental DNA levels. This is not a lower-chance result. Depending on your circumstances, options may include repeat sampling, diagnostic testing or no further testing. Repeat testing may also be inconclusive.
Follow-up arrangements: Ask who will explain the laboratory result, how it will be shared with your maternity team, and which referrals or appointments carry separate charges. Do not make an irreversible decision on an NIPT result alone.
Timing, suitability and preparation
From 10 weeks + 4 days at LPU
This is the clinic’s threshold for this combined appointment, subject to suitability. It is not a universal cut-off for every laboratory method. The scan helps assess your dates before blood sampling; it cannot guarantee a reportable result.
Tell us about your pregnancy
Before booking, mention twins or higher-order multiples, a vanishing twin, IVF, donor eggs, surrogacy, previous screening results and relevant medical history. Suitability and interpretation depend on the particular test and your circumstances.
Prepare for the scan
Follow the clinic’s preparation instructions. A comfortably full bladder may help an abdominal early pregnancy scan. Bring pregnancy dates, previous scans and screening reports. Tell reception about interpreter, accessibility or support requirements.
Your appointment
Discuss and book
Read the information and ask questions before deciding. Confirm your eligibility, the included panel, total price and result arrangements. Read the repeat-sample policy: one appropriate repeat blood collection and analysis after an inconclusive initial result is included at £0.
Ultrasound assessment
The sonographer assesses early development, dates and the number of babies. The findings may mean that testing needs to be deferred or that a different clinical pathway is appropriate.
Explanation and consent
Discuss what NIPT can and cannot show, possible outcomes and follow-up choices. Confirm your fetal-sex reporting preference. You can decline blood screening.
Maternal blood sample
Blood is taken from your arm and sent for laboratory analysis. No needle enters the womb. Sampling can cause discomfort, bruising, bleeding or faintness; infection is uncommon.
Results and next steps
Scan findings are discussed at the appointment and a digital report is provided. Confirm the current blood-test turnaround and result explanation arrangements; delays and repeat samples can extend the timeframe.

NIPT: frequently asked questions
How much does the NIPT test and scan cost?
The standard NIPT blood test with early pregnancy ultrasound is £549. The package covers screening for trisomies 21, 18 and 13, the blood sample, ultrasound assessment, explanation and a digital scan report. Optional fetal-sex reporting is included on request where the laboratory can provide it. Separate specialist consultations and diagnostic procedures such as CVS or amniocentesis are not included. If the laboratory issues an inconclusive or no-result report for your initial standard NIPT sample, the £549 package includes one repeat blood collection and laboratory analysis at no additional charge (£0), provided your clinician and the laboratory consider repeat testing appropriate. The repeat does not include another ultrasound scan. A repeat sample may also be inconclusive. If repeat testing is unsuitable, you may decline it or discuss other options with your maternity or fetal medicine team. A second repeat is not included or automatically arranged; any further service requires a separate clinical discussion and an agreed price before you proceed. Repeat sampling must not delay assessment or diagnostic testing recommended by your maternity team.
What does NIPT screen for?
The standard panel estimates the chance of Down’s syndrome (trisomy 21), Edwards’ syndrome (trisomy 18) and Patau’s syndrome (trisomy 13). It analyses cell-free DNA in the pregnant person’s blood; the pregnancy-related DNA mainly comes from the placenta. It does not screen for every genetic condition or physical difference.
Is NIPT a diagnosis?
No. A higher-chance result does not confirm that the baby has the condition, and a lower-chance result does not rule it out completely. Diagnostic testing may be offered to clarify a higher-chance result. You can accept or decline further testing after discussing the benefits, limitations and risks with your maternity or fetal medicine team.
How accurate is NIPT?
Performance varies by condition, test method and pregnancy circumstances. A detection rate describes how often the test identifies pregnancies affected by a condition. Positive predictive value (PPV) is the proportion of higher-chance results for a particular condition that are confirmed to be affected by that condition. These are different measures, and PPV depends on the underlying chance of the condition. Ask for the current information for the laboratory test being offered and discuss how it applies to you. False-positive, false-negative and inconclusive results are possible.
When can I have NIPT at LPU?
This clinic offers the combined NIPT and scan appointment from 10 weeks + 4 days, subject to suitability. This is our service’s booking threshold, rather than a universal biological cut-off for every NIPT test. The ultrasound helps assess gestational age and suitability before blood sampling. An inconclusive result remains possible after this stage.
Do I have to have screening?
No. Screening is optional. You may choose to have NIPT, decline it, or discuss other screening and diagnostic options with your maternity team. Declining screening does not remove your entitlement to routine NHS antenatal care. Take time to consider what you would want to know and how different results might affect you.
What happens after a higher-chance result?
Contact your maternity team or a fetal medicine specialist to discuss the result. They can explain the condition, your individual circumstances and options, which may include CVS or amniocentesis. NIPT alone cannot establish a diagnosis. You may choose diagnostic testing or no further testing. Ask the clinic how reports are shared and which follow-up services carry separate charges.
What does a lower-chance result mean?
It means the chance of the screened condition is reduced, but is not zero. NIPT does not exclude all chromosome conditions, genetic conditions or structural differences. Continue your routine maternity appointments and recommended ultrasound scans.
What is a no-result or inconclusive result?
Sometimes the laboratory cannot report a result. Reasons can include a low proportion of placental DNA in the sample and other technical or biological factors. This is not a lower-chance result and does not establish whether the baby is affected or unaffected. Discuss it with your maternity or fetal medicine team. Depending on your circumstances, options may include another blood sample, diagnostic testing or no further testing. One repeat blood collection and laboratory analysis is included at no extra charge (£0) after an initial inconclusive result, where clinically and laboratory appropriate. It does not include another scan. A repeat can also be inconclusive. A second repeat is not included; further options and any separate costs must be discussed before you proceed.
What are the risks of the appointment?
NIPT uses blood taken from your arm, without a needle entering the womb. Blood sampling may cause discomfort, bruising, bleeding or faintness; infection is uncommon. Ultrasound uses sound waves rather than ionising radiation. CVS and amniocentesis are different, invasive diagnostic procedures with their own risks, which should be discussed separately if offered.
Can fetal sex be reported?
Fetal-sex reporting is optional and is included on request where available and suitable for the pregnancy. Tell the team whether you want this information before the sample is sent. Results and reporting limitations depend on the laboratory and pregnancy circumstances; fetal sex is not the same as gender identity.
Can I have NIPT with twins or an IVF pregnancy?
Eligibility and reporting depend on the laboratory method and the pregnancy. Tell the clinic about twins or higher-order multiples, a vanishing twin, IVF, donor eggs, surrogacy, relevant medical conditions or previous screening findings before booking. These circumstances do not all automatically exclude testing, but may change suitability or interpretation.
How should I prepare?
Follow the clinic’s scan preparation instructions. A comfortably full bladder may help an abdominal early pregnancy scan; do not force fluids if you have been advised to restrict them. Bring previous scan or screening reports, your pregnancy dates and any IVF information. Tell reception about accessibility, communication or support needs.
How long will the results take?
Ultrasound findings are discussed at the appointment and a digital scan report is provided. Ask for the current laboratory turnaround, how the blood-test result will be explained and who to contact if it is delayed. Laboratory processing or repeat sampling may extend the expected timeframe.
Does NIPT replace NHS screening or the anomaly scan?
No. NIPT and ultrasound assess different things. Continue routine antenatal care and discuss your screening choices with your maternity team. The NHS combined screening pathway uses ultrasound and blood markers; NIPT analyses cell-free DNA. Availability and suitability depend on your circumstances and local NHS pathway. An early private scan does not replace the recommended fetal anomaly scan.
Do I need a referral, and can a support person attend?
No routine GP referral is needed for private booking. A partner or support person may attend; discuss any chaperone, privacy, interpreter or accessibility arrangements with reception beforehand. A requested clinician or appointment time is subject to availability.
When should I seek urgent care instead?
Do not wait for a routine private appointment if you have heavy bleeding, severe abdominal or pelvic pain, shoulder-tip pain, fainting, collapse or feel seriously unwell. Seek urgent maternity or early pregnancy assessment. Call 999 for collapse or a life-threatening emergency; use NHS 111 if you need urgent advice and are unsure where to go.
