Genes are the building blocks that keep our bodies healthy. Each human has around 20,000 genes in their body. However, sometimes a person can be born with extra genes, which can jeopardize a person’s health. To check for gene abnormalities, a doctor might recommend a prenatal testing method called cell-free fetal DNA.
Genetic testing, or DNA testing, is used to identify defects in the chromosome structure. If a doctor detects an abnormality, the patient meets the high-risk criteria that could harm the baby or mother’s health. Age-related complications can cause Down syndrome and other common chromosome defects. However, sometimes the physician can detect more serious defects with the baby’s chromosomes.
Genetic screenings are typically done during the first or second trimester. The physician will draw blood from the mother to determine the outcome. If the test comes out positive, we recommend discussing extensive testing options to carefully determine any genetic problems.
