It is offered to healthy people who are having difficulty achieving a viable pregnancy, and is usually taken by both partners.\u003c\/p\u003e\n\u003cp\u003eHumans have 22 pairs of non-sex chromosomes and one pair of sex chromosomes, making 46 in total. A typical result is reported as 46,XX or 46,XY. The analysis checks whether whole chromosomes or pieces of chromosomes are missing or duplicated, and whether pieces have been swapped between chromosomes, inverted or moved around. These are known as rearrangements. People who carry a rearrangement are usually healthy and have no other symptoms, but it can affect fertility, and that is the part of the test that matters in a reproductive health context.\u003c\/p\u003e\n\u003ch3\u003eWho this test is for\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRepeated miscarriages, or a family history of repeated miscarriages, from two or more\u003c\/li\u003e\n\u003cli\u003eTwo or more previous recurrent aneuploid pregnancies, such as trisomy 21\u003c\/li\u003e\n\u003cli\u003eIVF with two or more implantation failures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThere are no age, residency or other eligibility limits on this test.\u003c\/p\u003e\n\u003ch3\u003eHow the sample is taken\u003c\/h3\u003e\n\u003cp\u003eA simple blood draw of 4ml into lithium heparin tubes, taken by a professional in one of our clinics or by a nurse at your home. No fasting or other preparation is needed, though it helps to stay hydrated. Your sample is refrigerated and sent to the laboratory the same day.\u003c\/p\u003e\n\u003ch3\u003eYour results\u003c\/h3\u003e\n\u003cp\u003eResults take 12 to 14 working days. Analysis is carried out by clinical scientists at Eurofins Clinical Genetics UK in a laboratory accredited to ISO 15189, following ISCN 2024 nomenclature at a banding resolution of 400 to 550 bands, with a minimum of 20 cells analysed. If a result is outside the expected range, a clinical scientist at Eurofins Clinical Genetics UK will contact you and arrange a 15 to 30 minute video consultation to talk through what it means. Your partner or a family member is welcome to join.\u003c\/p\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eDo both partners need to be tested?\u003c\/h3\u003e\n\u003cp\u003eThe test is normally taken by both partners, as a rearrangement in either partner can affect the chance of a viable pregnancy. Each person needs their own blood sample.\u003c\/p\u003e\n\u003ch3\u003eDo I need to fast or prepare in any way?\u003c\/h3\u003e\n\u003cp\u003eNo. There are no fasting, timing or preparation requirements. Staying hydrated makes the blood draw easier.\u003c\/p\u003e\n\u003ch3\u003eHow long do results take?\u003c\/h3\u003e\n\u003cp\u003e12 to 14 working days from the laboratory receiving your sample.\u003c\/p\u003e\n\u003ch3\u003eWhat happens if my sample cannot be analysed?\u003c\/h3\u003e\n\u003cp\u003eAround one in ten samples cannot be analysed and needs to be repeated. If that happens, the repeat test is carried out free of charge.\u003c\/p\u003e\n\u003ch3\u003eWhat does a normal result look like?\u003c\/h3\u003e\n\u003cp\u003eA typical result is reported as 46,XX or 46,XY, meaning no chromosomal changes were seen in the cells analysed.\u003c\/p\u003e\n\u003ch3\u003eCan my results be shared with my GP or fertility specialist?\u003c\/h3\u003e\n\u003cp\u003eYes. Results can be shared with your GP or consultant fertility specialist on request, and we would encourage you to do so if anything unexpected is found.\u003c\/p\u003e\n\u003ch3\u003eIs a consultation included?\u003c\/h3\u003e\n\u003cp\u003eIf your result is outside the expected range, a 15 to 30 minute video consultation with Eurofins Clinical Genetics UK is arranged to explain the findings and what they mean for you.\u003c\/p\u003e\n\u003ch3\u003eWhat are the limits of this test?\u003c\/h3\u003e\n\u003cp\u003eChromosome analysis does not detect every genetic change. It cannot reliably identify changes present in only some cells, very small or subtle structural changes, or differences between tissues. Results should be interpreted alongside your medical history by a clinician.\u003c\/p\u003e","brand":"Goodbody Clinic Private Health Testing","offers":[{"title":"Blood taken by a professional in-clinic","offer_id":54692301865299,"sku":"KaryotypeEURO","price":295.0,"currency_code":"GBP","in_stock":true},{"title":"Book a home nurse visit to have your blood sample taken","offer_id":54692301898067,"sku":"KaryotypeEURO","price":310.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/0379\/2979\/files\/ChatGPTImageSep11_2026_11_58_24AM.png?v=1789124781","url":"https:\/\/goodbodyclinic.com\/products\/karyotype-test-chromosome-analysis-blood-test","provider":"Goodbody Clinic - Private Health Testing","version":"1.0","type":"link"}
