GENETIC TESTING Meaning and
Definition
-
Genetic testing refers to a medical procedure used to examine a person's genes, DNA, or chromosomes to determine the presence or absence of certain genetic conditions, inheritable diseases, or genetic variations. It involves analyzing an individual's genetic material to uncover potential mutations, genetic predispositions, and other inheritable traits.
This diagnostic procedure is conducted by obtaining a sample of bodily fluid, usually blood or saliva, which is then sent to a laboratory for analysis. The genetic material in the sample is carefully examined and sequenced to identify potential abnormalities or mutations. By comparing the patient's genetic information to established genetic markers or reference genomes, genetic testing can identify the presence of specific genetic disorders, genetic traits, or risk factors associated with certain diseases.
Genetic testing serves several purposes, including providing information about an individual's likelihood of developing a specific medical condition, determining the risk of passing on inherited disorders to offspring, predicting responses to certain medications, and enabling personalized medicine. It has applications in prenatal screening, newborn screening, carrier testing, diagnosis of genetic disorders, and identifying individuals at risk for hereditary cancer or cardiovascular diseases.
The results of genetic testing can have profound implications for individuals and their families, as they provide insight into potential health risks and may influence medical decisions. It is important to note that genetic testing is a complex and rapidly evolving field, requiring specialist expertise, ethical considerations, and informed consent.

Etymology of GENETIC TESTING
The word "genetic" comes from the Greek word "genetikos", which means "pertaining to generation or origin". It is derived from the Greek word "genesis", meaning "origin" or "birth". The term "testing" comes from the Middle English word "testen", which means "to bear witness". It can be traced back to the Old French word "tester", meaning "to witness or affirm". In the context of genetic testing, the word refers to the process of examining an individual's DNA or genes to ascertain information about their ancestry, the presence of genetic disorders, or potential disease risk factors.
