At One Stop Doctors we offer a range of  Consultant-led diagnostic services for pregnant women including pregnancy scans from 7 to 34 weeks.

These scans  are used at various stages throughout pregnancy to get a clear picture of baby and track baby’s growth and development. Pregnancy scans are an opportunity for many women and families to ‘see’ their baby and feel at ease regarding their baby’s development.

For more detailed information on the scans available, what they can tell you about your child and when they can be performed, please see below.

Early Pregnancy Scan /dating scan

7-11 weeks.

  • Description

    This scan helps you have reassurance in those crucial early weeks of pregnancy, after a confirmed positive pregnancy test. An early pregnancy scan will confirm the presence of a heartbeat and ascertain wellbeing of the baby in the early weeks of pregnancy. On this scan, the Practitioner can obtain measurements of the pregnancy sac and some measurements of the baby to confirm the number of weeks of pregnancy to establish an estimated due date. Therefore, this scan is also called a Dating Scan. This scan helps to exclude an ectopic pregnancy and provides reassurance in case of any early pregnancy pain or bleeding. The scan is done transabdominally (through your tummy) and so a slightly filled bladder before the scan is helpful. A detailed report with graphs for baby’s measurements will be provided by the Consultant.

  • Time and Cost

    Time taken: 10-15 minutes Cost of scan: £180.00

Nuchal Scan

11-13 weeks (+6 weeks)

  • Description

    Apart from confirming the baby’s heartbeat and establishing a due date (dating) this is the first scan in which the baby can be seen in greater detail. The baby’s head, trunk, arms, legs and some internal structures can be examined at this stage and we will also look at the placenta, amniotic fluid and umbilical cord. The doctor will measure the Nuchal Translucency (or NT) which is essentially the thickness of skin at the back of baby’s neck. In some babies with chromosomal abnormality such as Down’s Syndrome, and in some normal babies, this can be enlarged by fluid. As part of this exam blood samples will be taken from your arm and perform a blood test for two specific hormones. The result of this test will give you information about your individualised level of risk. From this information we can calculate the risk of your baby having Down’s Syndrome or two other less common chromosomal abnormalities called Edward’s Syndrome or Patau’s’ Syndrome. This is called the combined test for Down’s Syndrome. The combined test is not diagnostic and is only a screening test to give us a level of risk. A detailed report with graphs for baby’s measurements will be provided by the Consultant.

  • When will results be back?

    The blood tests should be available 24 hours post sample, this allows time for processing, receipt and appropriate reviews by the reviewing Consultant. How will the results be communicated? The results should be sent via encrypted email or by post, if email is not available. Should a result need to be conveyed by the supervising Consultant this would be done via a phone call.

  • What happens if Combined test shows high risk?

    In the event of a high-risk result, we would offer you Non-invasive Prenatal Test (NIPT) which can be done anytime after 10 weeks of pregnancy. This test is non-invasive involving an ultrasound scan and a simple and safe blood test. NIPT has a sensitivity of >99% for detection of Down’s Syndrome. Please ask for our information leaflet on NIPT from the One Stop Doctors front desk if you wish to enquire about the test.

  • Time and Cost

    Time taken: up to 30 minutes Cost of scan: £250

Detailed Foetal Anomaly Scan (the 20-week scan)

18-23 weeks

  • Description

    This is an extremely important detailed check of baby’s internal anatomy. The measurements of the baby’s head, tummy and legs are made and plotted on a chart and this establishes baby’s growth curve. We then continue the very thorough scan to check your baby’s heart, brain, face, spine, bowel, stomach, kidneys, limbs, hands and feet for any major abnormalities. We also check baby’s placenta, amniotic fluid and the umbilical cord. If you wish, you can also find out the sex of your baby from this scan. Ultrasound is a screening tool and cannot completely guarantee that there will be no minor structure abnormalities, but is a normal scan of baby’s anatomy at 20 weeks gives a very strong reassurance. A detailed report with graphs of baby’s measurements will be provided by the Consultant.

  • Time and cost

    Time take: approx. 30 minutes Cost of scan: £300

Foetal Growth and Wellbeing Scans with Dopplers

This scan can be done anytime between 24-40 weeks

  • Description

    Foetal Growth or Well-being scans can be performed at any stage starting from 24 weeks of pregnancy if you are concerned about the wellbeing of baby for any reason or wish for more information. This scan is not routinely available on the NHS. During this scan we measure the baby’s head, tummy and limbs and provide an estimate of baby’s weight. Normal velocity of growth is one of the best predictors of optimum placental function and foetal wellbeing and very often we recommend two-three growth scans done serially to ensure baby is putting on appropriate weight. We also look at baby’s movements, the amount of amniotic fluid around baby and location of the placenta. We will also assess the Doppler blood flow in the umbilical cord blood vessels. It is possible to tell the sex of your baby from this scan, but this becomes more difficult as you approach the end of your pregnancy. If wishes, serial scans for growth velocity, this can be offered. A detailed report with graphs of baby’s measurements will be provided by the Consultant with every scan.

  • Time and cost

    Time taken: 15-20 minutes Cost of scan: £240 (for single scan) Package of two scans £440 Package of three scans £640

Early Reassurance Scan

14-24 weeks

  • Description

    Reassurance scans can be performed at any stage after 14 weeks of pregnancy if you are concerned about the pregnancy at this stage for any reason. During this scan we measure the baby’s head, tummy and upper leg. We also look at baby’s movements, the amount of amniotic fluid, and location of the placenta. It may be possible to tell the sex of your baby from this scan after 16 weeks. You may wish to have this scan if you have had bleeding or have been unwell. A detailed report with graphs of baby’s measurements will be provided by the Consultant with every scan.

  • Time and cost

    Time taken: 10-15 minutes Cost of scan: £220

Sexing or Gender Scan

18-32 weeks

  • Description

    These scans can be performed at any stage after 16 weeks of pregnancy. Please note the scan is only done for couples who would like to know the sex of their baby for social and family reasons. We do not do it to assist in sex selection. Also included in the scan are measurements of baby’s head, tummy and leg, position of the baby and placenta and amniotic fluid. A detailed report with graphs of baby’s measurements will be provided by the Consultant with every scan.

  • Time and cost

    Time taken: 10-15 minutes Cost of scan: £220

NIPT (Non-Invasive Prenatal Testing / Harmony Blood Test)

Anytime after 10 weeks of pregnancy

  • Description

    The NIPT can detect, with 99% sensitivity, risk of Down’s Syndrome or other chromosomal abnormalities, making this the most accurate screening test available at present. A blood sample taken from the mother any time from approximately 10 weeks of pregnancy can be analysed for cell free foetal DNA, which gives information about DNA of the baby. The result of the sample blood test has a detection rate of more than 99% which greatly reduces the need for invasive testing by CVS or amniocentesis. This is great news for couples because it eliminates risk of miscarriage of the pregnancy associated with these more invasive tests. NIPT can also be used in twin or more, singleton donor and surrogate pregnancies. The blood test is done in association with a scan to check that everything is progressing well with the pregnancy.

  • Do I need this scan?

    If you are anxious about your baby having a chromosomal abnormality such as Downs, Edwards, Patau’s Syndrome or a sex chromosome abnormality for some reason (e.g. if you are aged 35 and above, have had a previous pregnancy affected by chromosomal abnormality or have a family history), then you can enquire about this test.

  • When will the results be back?

    The Harmony Blood Test results should be available 24 hours post samples, this allows time for processing, receipt and appropriate review by the reviewing Consultant.

  • Time and cost

    Time taken: 60 minutes Cost of scan and test, with full discussion of results: £575
