Mire való a vizsgálat?

Terhesség alatt annak a valószínűségi becslésére, hogy a születendő magzatnak bizonyos kromoszóma-rendellenessége, így Down-kór (a 21-es kromoszóma triszómiája), Edwards-szindróma (a 18-as kromoszóma triszómiája), illetve nyitott velőcsőzáródási rendellenessége van-e (például nyitott gerinc).

Mikor kell a vizsgálatot elvégezni?

Általában a terhesség 15. és 20. hete között.

Milyen mintára van szükség?

A könyökhajlati vénából nyert vérmintára.

Hogyan készüljek elő a vizsgálatra?

Nincs szükség előkészületre.
