Chorionic Villus Sampling Gold Coast
Waiting on genetic results is one of the harder parts of pregnancy, and for some women, waiting isn’t the only option. If an earlier screening test has flagged an increased chance of a chromosomal condition, or there’s a family history that needs closer investigation, your doctor may recommend chorionic villus sampling. It’s a test that can give clearer answers earlier in pregnancy than some of the alternatives, and at Haven Ultrasound, it’s performed by specialists who do this work every week.
CONSULTATIONS
What Is CVS?
Chorionic villus sampling, usually just called CVS, is a diagnostic test rather than a screening test. That distinction matters. Screening tests, like NIPT or the first trimester combined screening, estimate the chance that a baby has a particular condition. CVS, by contrast, looks directly at the baby’s genetic material and gives a definitive result for most chromosomal conditions.
The procedure involves taking a tiny sample of chorionic villi, the tissue that forms part of the placenta and shares the same genetic origin as the baby. Under continuous ultrasound guidance, a fine needle is passed either through the abdomen or, less commonly, through the cervix, to collect this sample. The tissue is then sent to a laboratory for genetic analysis. Most CVS pregnancy test appointments at Haven, including the consultation, the procedure and the recovery period, are completed within an hour.
When Is CVS Performed During Pregnancy
VS is typically carried out between 11 weeks and 13 weeks and 6 days of pregnancy. This window exists for a practical reason: the placenta needs to be developed enough to allow safe, accurate sampling, but testing this early still gives parents time to plan, seek further specialist input, or simply understand what’s ahead, well before the second trimester.
Timing is confirmed with a dating scan beforehand, since gestational age needs to be accurate before any invasive procedure is scheduled. This is something our team checks carefully at the pre-procedure consultation, alongside placental position and any other factors specific to your pregnancy.
Specialist-led procedures. CVS at Haven is performed by Maternal Fetal Medicine specialists with extensive experience in invasive prenatal testing, not delegated to general sonography staff.
Genetic counselling on site. Before your procedure, and again once results are available, our genetic counselling team can talk you through what the results mean, what they don’t mean, and what your options are from there.
Continuous ultrasound guidance. The needle placement is guided by real-time imaging throughout, which allows the sample to be taken as precisely and efficiently as possible.
Coordinated care with your doctor. A detailed report is sent to your referring doctor or obstetrician, so your ongoing pregnancy care stays connected rather than fragmented across providers.
Book Your CVS Appointment on the Gold Coast
If your doctor has raised chorionic villus sampling as an option, or you’d simply like more information before deciding, our team is here to talk it through. Many families find it helpful to first discuss non-invasive options through NIPT testing and genetic screening, or to book a consultation with our Maternal Fetal Medicine specialists to weigh up what’s right for their pregnancy. Referrals can be arranged through your doctor, and our friendly team can be reached directly to organise a chorionic villus sampling Gold Coast appointment at a time that suits you.
Frequently Asked Questions
Is CVS painful?
Most women describe the sensation as similar to a blood test or a period cramp, brief pressure or discomfort rather than significant pain. Local anaesthetic can be used for the abdominal approach if needed.
What are the risks of CVS?
As with any invasive prenatal procedure, CVS carries a small risk of complications, including miscarriage. Your specialist will talk through the risks relevant to your individual pregnancy at your consultation, so you can make an informed decision alongside your doctor.
How long do CVS results take?
A preliminary result for the major chromosomal conditions is often available within a few days, with full results, including any additional genetic analysis, typically taking one to two weeks. Your doctor and our genetic counselling team will keep you updated throughout.
Do I need a referral for CVS?
Yes. CVS is arranged through your doctor, obstetrician or midwife, who will provide the necessary referral and clinical information ahead of your appointment.
