Down sendromunun kesin tan\u0131s\u0131 bebe\u011fin h\u00fccrelerinin incelenmesi ile yap\u0131l\u0131r. Bunun i\u00e7in bebe\u011fin e\u015finden (koryon vill\u00fcs biyopsisi CVS), su kesesinden (amniyosentez AS) veya g\u00f6bek kordonundan (kordosentez KS) al\u0131nan \u00f6rneklerdeki bebe\u011fe ait h\u00fccreler kullan\u0131l\u0131r. Bu y\u00f6ntemlerde annenin karn\u0131ndan bat\u0131r\u0131lan uzun ince bir i\u011fnenin ucuna ba\u011flanan bir enjekt\u00f6re vakum uygulayarak bebek h\u00fccrelerini i\u00e7eren \u00f6rnekler elde edilir. Gebeli\u011fin ilk \u00fc\u00e7ay\u0131nda CVS, 16-22. Haftalar aras\u0131nda AS, 22 haftadan b\u00fcy\u00fck gebeliklerde AS veya KS tercih edilir.<\/p>\n
Tan\u0131 testleri\u00a0tamamen g\u00fcvenli de\u011fildir.

Bebekte Down sendromu olma riski ilk \u00fc\u00e7ay tarama testi, \u00fc\u00e7l\u00fc test, d\u00f6rtl\u00fc test veya ayr\u0131t\u0131l\u0131 2. Trimestre ultrasonografisi gibi bebe\u011fe ve anneye zarar vermeyen tarama y\u00f6ntemleri ile belirlenir. Ultrasonografi ile yap\u0131lan taramalarda Down sendromlar\u0131nda normal bebeklere oranla daha s\u0131k g\u00f6r\u00fclen belirte\u00e7ler (Ense saydaml\u0131\u011f\u0131nda art\u0131\u015f, burun kemi\u011fi yoklu\u011fu, ense plisi kal\u0131nl\u0131\u011f\u0131, kalpte yast\u0131k defekti, beyin omurilik s\u0131v\u0131s\u0131n\u0131 ta\u015f\u0131yan sarn\u0131\u00e7larda geni\u015fleme ve sa\u011f kola giden damar\u0131n normal konumunda olmamas\u0131 gibi) aran\u0131r. Her bir belirtecin spesifik bir risk artt\u0131rma katsay\u0131s\u0131 vard\u0131r. Bu katsay\u0131 annenin ya\u015fa veya daha \u00f6nce yap\u0131lan testlere ba\u011fl\u0131 test \u00f6ncesi riski ile \u00e7arp\u0131larak toplam test sonras\u0131 risk bulunur. Bu riskin belirli bir e\u015fik de\u011ferden (ortalama 1\/300) y\u00fcksek bulunmas\u0131 halinde kesin tan\u0131 testi \u00f6nerilir. Bu \u015fekilde kesin tan\u0131 testi nisbeten k\u00fc\u00e7\u00fck bir y\u00fcksek risk grubuna (yakla\u015f\u0131k toplam\u0131n %5’i) uyguland\u0131\u011f\u0131 halde Down sendromlular\u0131n %90’\u0131ndan fazlas\u0131n\u0131n anne karn\u0131nda tesbit edilmesi m\u00fcmk\u00fcn olur.<\/p>\n
