There are some techniques, the biopsy of a chorion in terms of 9 11 weeks of pregnancy is most actual, there are techniques kordo-and amniotsenteza, through an abdominal wall. Risk of an abortion - 2 %. The taught variant investigate or research a cytogenetic method (the analysis of a karyotype) for revealing a chromosomal pathology (a syndrome of the Down, Shereshevskogo-Turner, Kljajnfeltera, etc.), and also on this term probably antenatal definition of a floor of a fetus and to solve the problem a doubtful paternity (accuracy of a technique 99, 99 %). If in family there is a child with a pathology (the diagnosis is established or installed) diagnostics of the same pathology at a fetus molekuljarno-genetic methods is possible or probable. It is more exact and dear or expensive analysis. Accuracy of both techniques high, the order of 98 %. Methods dear or expensive enough (in Moscow it costs or stands from 5 6 thousand roubles and above).
