GENETIC SCREENING Meaning and
Definition
-
Genetic screening refers to the process of analyzing an individual's genetic makeup to identify any potential genetic disorders, disease predispositions, or inherited traits. It involves the examination of an individual's DNA sequence, chromosomes, or specific genes to determine the presence of certain genetic variations or mutations that may be associated with specific conditions or characteristics.
This screening process can be performed on both embryos (prenatal screening) and individuals at any age (postnatal screening). Prenatal screening is commonly used during pregnancy to identify any genetic abnormalities in the developing fetus, such as Down syndrome or cystic fibrosis. Postnatal screening, on the other hand, is typically performed on newborns to detect any inherited conditions, such as phenylketonuria or sickle cell anemia.
Genetic screening can be done through various techniques, including genetic testing, which involves taking a sample of blood, saliva, or other tissues for analysis. The genetic material in the sample is then analyzed using advanced laboratory techniques to identify any genetic variations or abnormalities. The results obtained from the screening process can help individuals and healthcare professionals make informed decisions regarding medical treatment, reproductive choices, or lifestyle modifications to manage or prevent certain genetic conditions.
Overall, genetic screening plays a crucial role in diagnosing genetic disorders early, facilitating appropriate medical interventions, and empowering individuals and families to make informed decisions about their healthcare.

Etymology of GENETIC SCREENING
The word "genetic" originates from the Greek word "genetikos", which is derived from "genesis", meaning "origin" or "creation". It is related to the Greek word "genos", meaning "race" or "kind".
"Screening", on the other hand, comes from the Old English word "scrēn", which means "a protective barrier". The term later referred to a partition used for protection or concealment.
Therefore, "genetic screening" is a term that combines the idea of examining and assessing one's genetic makeup or traits with the concept of using protective barriers or partitions to separate and identify particular genetic characteristics.
