GN 301 Module 2: Prenatal Testing and IVF

PGD

used before the transfer so you would know whether the embryo had any genetic disorders before implantation.

amniocentesis

a needle is put through the stomach which sucks amniotic fluid from the fetus.

CVS (Chorionic Villus Sampling)

chorion is taken from a fetus’s genotype by inserting a needle into the womb.

Cells

________ are checked from the placenta to detect chromosomal abnormalities.

amniotic fluid

The ________ extracted can tell if the fetus has any chromosome abnormalities or genetic disorders.

cell-free DNA testing

blood is taken from the mothers arm.

Why might one or another procedure be used?

You might want to use ultrasounds or cell-free DNA testing if you’re worried about keeping your baby safe and want to avoid risks. However, if you’re concerned about your baby having a genetic disorder, you may want to try CVS or amniocentesis because these can show you your baby’s genotype before they are born.

How is the information obtained from ultrasounds?

In ultrasounds, sound waves are used to form pictures inside the body.

How is the information obtained from amniocentesis?

In amniocentesis, a needle is put through the stomach which sucks amniotic fluid from the fetus.

How is the information obtained from CVS?

In CVS (Chorionic Villus Sampling), chorion is taken from a fetus’s genotype by inserting a needle into the womb.

How is the information obtained from Cell-Free DNA Testing?

In cell-free DNA testing, blood is taken from the mother’s arm.

What type of info is obtained from ultrasounds?

You can observe the development of a fetus, check for spine defects, head size, and confirm due dates.

What type of info is obtained from amniocentesis?

The amniotic fluid extracted can tell if the fetus has any chromosome abnormalities or genetic disorders.

What type of info is obtained from CVS?

Cells are checked from the placenta to detect chromosomal abnormalities.

What type of info is obtained from cell-free DNA testing?

You are able to see microdeletion or microduplication in bin count.

How can this info be used from ultrasounds?

You can find out when your baby is due or if they have any spinal deformities.

How can this info be used from amniocentesis?

You can find out if your fetus has any chromosomal abnormalities or genetic disorders with genetic testing.

How can this info be used from CVS?

You can find out if your baby has any chromosomal abnormalities.

How can this info be used from cell-free DNA testing?

You can find out whether your baby will have genetic disorders like Down Syndrome or trisomy 18.
