Genetic Testing Before Pregnancy
Carrier Screening
Carrier screening looks for genetic variants associated with inherited conditions that could be passed on to a child. Carriers of many autosomal recessive conditions are healthy and may have no family history of the condition. Screening can therefore identify reproductive risks that would otherwise be unknown.
Our expanded carrier screening can assess hundreds of genes, including conditions such as:
Cystic fibrosis
Spinal muscular atrophy (SMA)
Fragile X syndrome
Sickle cell disease and thalassaemia
Duchenne and Becker muscular dystrophy
For most autosomal recessive conditions, if both partners carry a clinically significant variant in the same gene, each pregnancy has a 1 in 4 chance of being affected. Other conditions, including X-linked disorders such as Fragile X syndrome and Duchenne muscular dystrophy, follow different inheritance patterns, which your clinician will explain
Carrier screening may be right for you if you are:
Planning a pregnancy or considering IVF
Pregnant and have not previously been screened
Using donor eggs or sperm
Aware of an inherited condition in your family
Related to your partner by blood

Advanced Genetic Testing During Pregnancy
Non-Invasive Prenatal Testing (NIPT)
Non-Invasive Prenatal Testing (NIPT) is a simple maternal blood test available from around 10 weeks of pregnancy. It analyses cell-free DNA in the maternal bloodstream, most of which originates from the placenta. NIPT is a highly accurate screening test, particularly for Down’s syndrome, and also screens for Edwards’ and Patau’s syndromes. Its performance varies between conditions and laboratories. It does not provide a definitive diagnosis, and a higher-chance result should usually be confirmed with CVS or amniocentesis. NIPT carries no miscarriage risk.
Diagnostic Testing: CVS and Amniocentesis
When a definitive answer is needed, our consultants can arrange:
Chorionic villus sampling (CVS): placental tissue sampling, usually performed after 11 weeks
Amniocentesis: testing of amniotic fluid cells, usually available from 15 weeks
Both are invasive procedures. When performed by an appropriately trained operator, the additional risk of miscarriage is likely to be below 0.5%, although the individual risk will be discussed during consultation.
Genetic Testing at a Glance
Test | When It's Used | What It Tells You |
Carrier screening | Before pregnancy, before IVF, or in early pregnancy | Whether you or your partner carry inherited gene changes |
NIPT | From around 10 weeks | Chance of common chromosome conditions (screening) |
CVS / Amniocentesis | After counselling, when a diagnostic answer is needed | A definitive result for the conditions tested |

Understanding Your Genetic Results
A genetic result is never just a number on a page. Your consultant will explain what it means for your pregnancy, whether partner testing is recommended, and whether any further testing should be considered.
A negative result is reassuring but does not remove all risk, as no test screens for every condition. Being identified as a carrier does not usually affect your own health. It simply means your partner may need testing, and the implications for your pregnancy can be discussed and planned for.

Yes. Preconception carrier screening is available privately in the UK for individuals and couples who want to understand their genetic risk before trying to conceive.
How accurate is private prenatal genetic testing?
NIPT is a highly accurate screening test, particularly for Down’s syndrome, and also screens for Edwards’ and Patau’s syndromes. Its performance varies between conditions and laboratories. It does not provide a definitive diagnosis, and a higher-chance result should usually be confirmed with CVS or amniocentesis.
At what stage of pregnancy can I have genetic testing?
