There have been many opinions regarding the safety
of genetic testing. One can look into a number of instances that aligns to the
effectiveness of this new revolutionary diagnosis and treatment method. Genetic
testing is suggested in order to find out whether the said person is a carrier
of any genetic condition and is likely to pass on the same to his offspring.
The testing also provides information on the genetic
configuration of a person and whether he is likely to contract any genetic
disorder even before the appearance of the symptoms. That is it can bring out
all hidden information that are relative to the well being of the person and
his unborn children.

Equation for Pregnant Women
As regards the safety of genetic testing on pregnant
women, there are a few minor hitches. These risks are considered to be a likely
outcome and not an assured danger. Prenatal genetic testing is done of pregnant
women to find out whether the fetus has any genetic abnormality. It is true
that under certain conditions, a miscarriage is a possibility but, what needs
to be understood that it is a probable side effect and not a sure-shot outcome.
are the Safe Options?
According to experts and researchers, CVS and
amniocentesis are the two considerably safe options. If a review of an
international research is considered, it is discovered that if amniocentesis is
carried out in the second trimester that is post sixteen weeks of conception,
the risk of miscarriage is one extra in every hundred procedures. While, if the
amniocentesis is early that is, carried out in the first semester, it is two
extra for every hundred procedure.
are the Two Genetic Testing Procedures Risky at All?
– This technique is widely suggested as it can effectively detect any genetic
or chromosomal abnormality. Under a clinical setting a narrow catheter is
inserted into the uterus through the abdomen. A small amount of amniotic fluid
is drawn out from the amniotic sac and used as a sample for analysis. A risk of
miscarriage is there due to the injury caused to the amniotic sac.
– The accuracy rate of Chorionic villus sampling or CVS is similar to that of
amniocentesis. The placenta has tiny branchlike projections called the
chorionic villi. By the help of an ultrasound a catheter or a thin needle is
inserted through the cervix or abdomen depending on the position of the
placenta. A sample is then removed for analysis for genetic and chromosomal
abnormality. The risk factor is the same as amniocentesis.
Since both the tests are performed under local
anesthesia, there is no pain or discomfort usually experienced. Apart from
miscarriage there is a likelihood of maternal infection as a side effect of the
tests. But is has been observed that the risk factors gets considerably lowered
when the tests are performed by extremely experienced practitioners and the
clinical setting has excellent hygienic environment.
