To this day, the risk of genetic diseases in the newborn is very high - the baby may be born with Down syndrome , Patau, Edwards, Turner. This severe disease, have in general a poor prognosis; they are accompanied by mental retardation, psychomotor and physical development of the child. The vast majority of genetic diseases or completely incurable or very poorly amenable to correction. Most methods of prenatal diagnosis produce results too late or are of different nature risks such as infection of the fetus.
In 2012, a group of Russian scientists has developed a new, safe method of prenatal diagnosis: Dot-test - a non-invasive method for studying the fetus, which is able to minimize the possibility of having a child with a genetic disorder. The accuracy of the technology has been confirmed by clinical studies, after which, in 2013, entered the market.
1. Early diagnosis of fetal
Dot-test is carried out starting from the 10th week of pregnancy; expert opinions are prepared within 12 days. Thus, a 12-week pregnant woman will already have all the data on the risk of severe illness in her child. Older methods of diagnosis - amniocentesis platsentotsentez, cordocentesis much longer time. For example, amniocentesis carried out between 10 and 14 weeks platsentotsentez - between 15 and 19, as cordocentesis - and at between 20 and 22. Preparation of research results takes at least two or three weeks, that is, the family does not receive data before 22 weeks. By this time, the fetus will have viable, and time to think about the continuation of the pregnancy will not.
2. High-precision results
The accuracy of the diagnosis of major trisomies is very high - it reaches 99.7%. With the data provided by the laboratory after the DOT test, the parents of the future child can not worry about eliminating all background birthday genetically sick child.
Dot test can take absolutely any woman with a singleton pregnancy, to hedge against adverse effects. This is a major breakthrough: earlier prenatal diagnosis sent only those patients who had more than one risk factor. Therefore, the remaining investigations were women, and even in the absence of factors possessing gave birth to children patients.
3. Full safety for mother and child
DOT-test - a non-invasive method of diagnosis of the fetus. That is, it is performed without tissue penetration; for the passage of the study need to be tested venous blood - it is absolutely safe. Other technologies are less reliable in this regard: for example, the methods of amniocentesis, cordocentesis or chorionic villus sampling are quite dangerous - they can lead to a forced abortion.
4. Successful clinical experience
Of the more than 1,000 children born of mothers who have successfully passed the DOT test, all babies were healthy. High-reliability Dot test actually eliminates genetic disorders of the fetus.
5. Additional research opportunities
At the request of the mother, the experts can install the Rh factor and sex of the child. Knowledge of the Rh factor Rh help avoid conflict - it occurs when the mother is Rh negative and the baby inherits the positive from the father. Rh factor is unfavorable for the growth and development of the embryo, and can lead to miscarriage or fetal death.
6. High qualification of Research
In developing DOT test was attended by members of the Russian Academy of Sciences. Research laboratory located in the Science Park of Moscow State University, all analyzes are carried out on equipment of last generation.
To eliminate the possibility of chromosomal disorders in the unborn child, pregnant women need to contact the Medical Center and deliver the venous blood. The results will be delivered to the patient and her physician within 12 days; based on them will be to draw conclusions about the future management of pregnancy.
