A DNA Paternity Test can be performed quickly
and accurately before a child is born. There are two methods
to collect a DNA sample from a child prenatally for DNA testing:
Chorionic Villus Sampling (CVS)
Chorionic villus sampling is performed at an earlier stage
of pregnancy than amniocentesis, generally around the 10th
week of pregnancy. During CVS collection, a small amount of
tissue is retrieved from the placenta by an obstetrician.
This procedure is usually painless.
Amniocentesis
Amniocentesis is generally performed at a later stage than
Chorionic Villus Sampling, usually after the 10th to 15th
week of pregnancy. During amniocentesis, a small amount of
amniotic fluid is withdrawn transabdominally by an obstetrician
with the aid of ultrasound guidance.
After the samples are collected by your physician, they are
forwarded directly to our laboratory for DNA testing. Please
note that the procedures indicated above have a small risk
to the foetus (e.g. miscarriage). Clients who are considering
prenatal DNA testing should consult with their obstetrician
to discuss the risks involved. Our laboratory advises all
clients who are considering prenatal paternity test to consider
refraining until the child is born.
The cost for prenatal testing is $255 US (does not include
any fees charged by the physician for sample collection).
The shipping fee for the amniotic fluid kit is $25 US (includes
kit and delivery). Results are available 7 - 9 days from the
date that our laboratory receives the samples.
