Genetic testing makes it possible for medical practitioners to detect defective or missing genes. With the information gotten through genetic testing, a doctor can determine if you, your partner, or your baby could have some medical conditions due to genetic disposition. Winter Park genetic testing involves the collection of small blood samples or body tissues for analysis. It can use different types of tissues and fluids. The kind of gene test you need varies depending on the condition your doctor wants to check for.
Genetic Testing During Pregnancy
When you take a genetic test during pregnancy, a blood test can help screen for some disorders. If the blood test finds a potential problem, a doctor may recommend chorionic villus sampling or amniocentesis.
An amniocentesis test is done between the 12th and 20th week of pregnancy. A doctor will insert a hollow needle into your abdomen during the trial and remove a small amount of amniotic fluid surrounding the developing fetus. They will check it for any genetic problems. It can also help identify the gender of the child. If you are at risk of premature birth, it can show the development of the baby’s lungs. It comes with a bit of a risk of inducing a miscarriage.
Chorionic villus sampling is done between the 10th and 12th weeks of pregnancy. During the test, the doctor removes a piece of the placenta. To check for any genetic problems in the fetus. Chorionic villus sampling can induce a miscarriage, but the risk remains low.
Why Do You Need Genetic Testing?
A doctor may ask you to go for genetic testing due to many different reasons. If you are pregnant and older than 34 years, your chances of having a baby with a chromosomal problem increase. Children of older fathers also risk developing new dominant genetic mutations resulting from a single congenital disability that has not affected anyone in the family in the past. You may also need genetic testing if you had a prenatal screening test showing abnormal results pointing towards a potentially genetic problem.
Another reason why you may need genetic testing is if you plan on starting a family and you, your partner, or a close relative to one of you has an inherited disease. You may also be a genetic disease carrier even though you may not show any signs of illness since some genetic disorders are recessive. This means that you can only notice the symptoms if someone inherits two copies of the same gene; each parent contributes one gene. Although children who inherit one normal gene and one problem gene from either parent will not show any symptoms of a recessive condition, they have a 50% chance of passing it on to their children.
Other reasons for getting a genetic test include having a child with a severe congenital disability, having two or more miscarriages, or having previously delivered a stillborn child with signs of a genetic illness.
To summarize, a genetic test aims at detecting defective or missing genes. A genetic test can help screen for some disorders during pregnancy, but you may need further sampling to diagnose genetic conditions that may affect the fetus. Your doctor may recommend genetic testing due to various circumstances.
