Newborn Genetic Screening in London
Newborn genetic screening uses advanced DNA testing to look for serious early-onset genetic conditions that may not be obvious at birth. The aim is to give families and clinicians earlier clarity and a practical plan, when relevant.
Newborn genetic screening at London Pregnancy Clinic
At London Pregnancy Clinic, newborn genetic screening is offered with support from Jeen Health genetic counsellors so your testing is:
- chosen for the right reasons (not “just in case”)
- clearly explained (what it can and can’t tell you)
- followed by a practical next step plan if something is found
What sample is used?
Newborn genetic screening is completed using a cheek (buccal) swab sample collected at home. Your kit is sent to your address and returned to the lab for analysis. Turnaround time: typically 2–3 weeks from sample receipt.
Why isn’t newborn genetic screening suitable for everyone?
While this test can be helpful, it isn’t the right fit for every family because:
- It does not test for every genetic condition
- A negative result reduces risk within what’s tested, but can’t rule out all causes of illness.
- A positive result can raise questions for the wider family and may require confirmatory steps and clinical follow-up.
When to book a clinical geneticist
If your baby has symptoms, unusual growth patterns, or features that may suggest a genetic syndrome, the most helpful first step can be a clinical geneticist consultation. A clinical geneticist can:
- review medical + family history in depth
- perform a physical examination where appropriate
- recommend the most suitable test (and avoid unnecessary testing)
- provide a plan for management and monitoring, including referrals and follow-up
