#Pregnancy Genetic Test
It is important to know the genetic health of a fetus before it’s born, and Pregnancy Genetic Test (PGT) is a great way to do that. PGT can identify potential genetic disorders that a fetus may have, as well as provide couples with information about the health of their child. PGT is a convenient, non-invasive way for couples to determine the genetic status of their baby before birth.
##What Is Pregnancy Genetic Testing?
Pregnancy genetic testing (PGT) is a testing procedure used to assess a fetus’s genetic makeup. The test utilizes a sample of the mother’s blood or fluid taken from the placenta or amniotic sac in order to examine chromosomes and genes. Depending on the disorder being tested for, the testing may range from analyzing a single gene to analyzing several thousands of genes.
##How Is Pregnancy Genetic Testing Conducted?
There are three main types of PGT:
– Non-Invasive Prenatal Testing (NIPT): This is the most common form of PGT and it involves collecting a sample of the mother’s blood in order to analyze fetal DNA that is found in the mother’s blood. NIPT is primarily used to screen for chromosomal disorders such as Down Syndrome.
– Invasive Prenatal Testing: This type of testing involves taking a sample of the amniotic fluid or placenta in order to directly analyze fetal genetic material. Invasive Prenatal Testing carries a higher risk of miscarriage, so it is typically only used to confirm the results of a NIPT, or if the results of a NIPT come back inconclusive.
– Preimplantation Genetic Testing (PGT-A): PGT-A is a type of testing that is conducted during in vitro fertilization. During this test, an embryo’s chromosomes are tested in order to determine if there are any genetic disorders present.
##What Is PGT Used For?
PGT provides couples with information about the chances their baby has of having certain conditions or diseases. Many couples opt for PGT so they can prepare for additional support that may be needed if their baby is born with a genetic disorder. PGT is also used to identify potential genetic issues before conception so couples can make informed decisions on starting a family.
PGT can test for a variety of diseases and disorders, including:
– Chromosomal abnormalities, such as Down Syndrome
– Single gene disorders, such as cystic fibrosis
– Multi-factorial disorders, such as cleft lip and cleft palate
##What Are The Benefits Of Pregnancy Genetic Testing?
PGT offers couples peace of mind when it comes to their unborn baby’s health. If a potentially serious condition can be identified ahead of time, a couple can make informed decisions about their pregnancy and/or how they will support their future baby.
The benefits of PGT include:
– Learn about potential genetic issues before birth
– Prepare for the future health of a baby
– Make informed decisions about conception
– Help detect and select against serious genetic disorders
– Assess the probabilities of the chances for inherited diseases
– Screen for chromosomal abnormalities in embryos created via IVF
PGT is an essential tool for any couple wanting to gain more insight into their unborn baby’s health. Genetic testing can help prepare couples for life with a potentially special needs child, or give them the peace of mind that all is well with their unborn baby.
