Dear Andrey! To a question from 25.10.2004 11.33.15 you have told or said, that it will be necessary to pass or take place the triad test for a syndrome of the Down. Excuse for denseness, and what is it? It is such analysis of a blood? What % of a guarantee gives this test? And more a question: diagnostics is how much exact with. The Down under the analysis of an amniotic liquid?

[Andrey]

The dear Lena, at the triad test or dough;father-in-law investigate or research a blood on alfa-a fetoprotein (AFP), chorionic Gonadotropinum (HG) and nekonjugirovannyj a theelol (NE). If parameters normal (and they still depend on age of mother) the probability of a birth of the child with Daunizmom is minimal. If pokzateli above norm or rate it does not mean, that at a fetus any disturbances, simply probability of a birth of the child with a syndrome is raised or increased. In etov a case it is necessary to study or investigate a karyotype of a fetus (do or make aminpunktsiju for a capture of an amniotic liquid). Whether the cytogenetic analysis of a karyotype from 100 % probability will specify is at a fetus kaki--or chromosomal disturbances (including a syndrome of the Down)
