Genetic Screening Before Pregnancy
Introduction
Genetic screening is used to determine whether a couple is at increased risk of having a baby with a hereditary genetic disorder. Hereditary genetic disorders are Overview of Chromosome and Gene Disorders that are passed down from generation to generation. Screening involves assessing the couple’s family history and, if needed, analysis of blood or tissue samples (such as cells from the inside of the cheek). Any couple can request genetic screening, but screening is particularly recommended when One or both partners know they have a genetic abnormality. Family members have a genetic abnormality. Partners belong to a high-risk ethnic group. Some genetic disorders are not hereditary (see Overview of Genetic Disorders ) and thus cannot be identified by screening the parents.
