> Tritest and fetal nuchal translucency: when and if you do the exams

Having just turned 28 years of age; and being the first pregnancy and not having a family history of hereditary diseases, ask for advice on make-or-less the following two tests: tritest and nuchal translucency.

it is a very difficult question, because it; don’t tell us if you would like to terminate the pregnancy of a fetus with a chromosome complement is not regular. If this is your intention is clear that you have to think that if you do nothing, you have a percentage that nearly matches the one-per-thousand of having a child with down syndrome. This is in reality the only alteration which we discuss as the human race is quite common. Jumps from a risk of one in two thousand to 18 years, to one to fifteen to 45 years. Quant is one to a thousand? So? It’s a little? Only you and your husband or your partner, you can know if you want to count the chromosomes of the fetus. Once you have decided if you want or don’t want to count them, the tritest può help:

  • think of it, if you give risk custom very più bottom;
  • get free amniocentesis if the risk is very più high;
  • to nothing, in case the estimated risk from the test, but equal to that già did you know for età.

L’ ecografia trasnucale

I heard about a new diagnostic technique for the genetic diseases that it is called ULTRASOUND TRANSNUCALE .

I Would like to know what is, if è true that for the certainty of the results può be considered in lieu of amniocentesis, if this is also provided free of charge by the health service after 35 years of età , if and where it is possible to undergo such examination in Milan.

are You referring to the ultrasound to assess nuchal translucency, i.e.; the thickness of the fold behind the neck of the fetus, which the più of the times is altered in fetuses affected by Down’s syndrome. Currently, in the majority of the services it is inserted in an analysis group called “bitest” and which also provides for two drawings of blood. These data are entered in a computer system that recalculates a risk più custom for that child. If the risk is greater than one to three hundred, usually, it is recommended to perform amniocentesis and practice for free.

The problem of this type of examination is that the answer 1 in the fourteenth century, for example, means “out of three hundred children with this alteration a is definitely Down,” that does not mean that your it is.

answer 1 to 2000 means that “about two thousand children with this alteration a is Down”, but this, even if è più reassuring, it does not mean that your son is not.In other words, between a probability and a certainty, there is a certain difference. In addition, after 35 years the risk is already high for età and it is not recommended più.

However, if you don’t want to do the amniocentesis, and are willing, together with the papà of the child, to settle for a probabilityà, you can use these exams indirect. You could ask for a genetic counseling Clinic of the Clinica Mangiagalli, in the your in the cityà, phone 02/57992319-2321, and talk with them about your concerns. In Rome the bitest is under 35 years of age, between 12 and 13 weeks, and is charged for a ticket 44 euros.
