Karyotype Test in London

Karyotype testing in London, made simple

Sample collection happens at our central London partner clinic, just off Marylebone Road - around the corner from Harley Street and three minutes from Oxford Circus, so getting to your appointment is straightforward whether you're travelling locally or coming in from the wider region. London families weighing genetic options often have the broadest cultural-heritage diversity in the UK, which is why our 600+ panel was developed for the city in the first place.

A karyotype test in London looks for whole-chromosome differences that microarray and prenatal screening tests miss - translocations, large duplications and deletions, and structural abnormalities that explain pregnancy loss, infertility, or developmental concerns. Our London customers most often book this test after recurrent miscarriage, before fertility treatment, or to clarify findings from earlier prenatal screening.

Results come back in 2-3 weeks via secure portal. If you would like a clinical-genetics consultation to talk your report through, you can book one at any time. The same Jeen clinical team handles every step from booking through results - no handoffs, no gaps. If you'd prefer a home blood draw instead of attending the London clinic, our mobile phlebotomist option covers most of the local postcodes.
