Genetic Screening

Genetic Screening


Genetic screening is a type of medical test that identifies changes in chromosomes, genes, or proteins. It's often used to detect inherited disorders, determine a person's risk of developing certain diseases, or help guide medical decisions for treatment and prevention.

Types of Genetic Screening

Newborn Screening

Done shortly after birth to identify genetic disorders that can be treated early.

Commonly tests for conditions like phenylketonuria (PKU), cystic fibrosis, and sickle cell disease.

Carrier Screening

Checks if a person carries a gene for a genetic disorder (even if they don’t have symptoms).

Often used before or during pregnancy.

Prenatal Screening

Performed during pregnancy to assess the risk of the fetus having genetic conditions like Down syndrome or trisomy 18.

Includes blood tests and ultrasound; may be followed by diagnostic tests like amniocentesis.

Preimplantation Genetic Diagnosis (PGD)

Used with IVF to test embryos for specific genetic conditions before implantation.

Predictive or Presymptomatic Testing

Helps identify risk for developing diseases later in life (e.g., BRCA1/2 for breast and ovarian cancer, Huntington's disease).
