Types of Screening Tests For Genetic Disorders

Genetic screening tests are specific medical tests that help in the identification of changes that take place in a person’s genes, proteins, or even the chromosomes. These tests play a crucial role when it comes to testing for genetic disorders. They identify a specific gene that can lead to genetic disorders. Here we will take you through some of the types of genetic screening tests that can identify genetic disorders.

Newborn Screening

This type of screening test is for baby’s just after their birth to trace out the genetic disorders. In case any disorders are traced, they can be treated at an early stage. Newborn screening is extremely essential as though your baby might be healthy, there are some conditions that are not visible but can cause serious problems later. Infants should be tested for congenital hypothyroidism (a disorder of the thyroid gland).

Diagnostic testing

As the name suggests, Diagnostic testing is for the identification of some specific condition. Diagnostic testing for genetic disorders helps in the confirmation when some specific condition is traced. This tracing is done on the basis of physical signs and symptoms. This test can be performed before birth and can also be carried out at any time during a person’s life.

Prenatal testing

Prenatal testing is used to detect changes in a fetus’s genes or chromosomes before birth. This type of testing is offered during pregnancy if there is an increased risk that the baby will have a genetic or chromosomal disorder. In some cases, prenatal testing can lessen a couple’s uncertainty or help them make decisions about a pregnancy. It cannot identify all possible inherited disorders and birth defects.
