Invasive Fetal Medicine Procedures — Amniocentesis and CVS
Invasive prenatal procedures — amniocentesis and chorionic villus sampling — are used when screening findings or family history make genetic diagnosis necessary. The decision to proceed is shared between the patient and the clinician after thorough counselling about the probability of finding a condition, the procedural risk (small but real), and the implications of the result. These are not routine procedures; they are reserved for situations where the genetic information will materially change pregnancy decisions.
Our approach to invasive procedures
Every patient considering an invasive procedure receives structured pre-procedure counselling: indications, what the result will and won’t tell, procedural technique, miscarriage risk (current data suggests below 0.5% in experienced hands), and what happens if a positive result is found. The procedure itself is performed under ultrasound guidance with continuous monitoring; recovery is typically uncomplicated.
Amniocentesis
Performed from around 15 weeks. A small volume of amniotic fluid is sampled transabdominally under ultrasound guidance. Fetal cells in the fluid undergo karyotyping or specific genetic testing. Used for diagnostic confirmation after positive screening, advanced maternal age combined with anxiety about uncertainty, or specific family-history indications.
Chorionic Villus Sampling (CVS)
Performed from 11 weeks. Placental tissue is sampled transabdominally or transcervically under ultrasound guidance. Allows earlier diagnostic information than amniocentesis. Used where early diagnosis materially affects decision-making.
Post-procedure care
Patients receive structured post-procedure information (warning symptoms, when to call), and we contact each patient personally with results. The conversation about a result — whether reassuring or otherwise — is unhurried.

Where this fits
Invasive procedures typically follow positive findings from screening or scans. Results inform decisions about specific conditions.

CVS (10-13 weeks) and amniocentesis (15+ weeks) procedure-related miscarriage rates are approximately 0.1-0.3% when performed by experienced operators. Counselling should cover timing, accuracy, and recovery.

Invasive Fetal Medicine Procedures is part of the broader fetal medicine programme. The main fetal medicine pillar covers the complete pregnancy ultrasound schedule.
Fetal-medicine procedures — precise answers, carefully counselled
When screening raises a question, a fetal-medicine procedure can give a definitive answer. The procedures in this area — chorionic villus sampling, amniocentesis and related interventions — are offered for a specific indication, never routinely, and always with full counselling about what each can tell you and its small risks.
Our principles
We perform these only when the information will genuinely change your care, under continuous ultrasound guidance by experienced hands, with honest discussion of the procedure-related risk beforehand. Where a non-invasive test can answer the question, we choose it first.
Explore the individual procedures for what each involves, when it is appropriate, and the alternatives — and we will always help you decide what is right for your pregnancy rather than presenting tests as a formality.
