Genetic screening is a process which is used to determine the heterozygosity and the potential of carrying a genetic disease in individuals belonging to the same population. In this way, the subgroup of people is identified which either have the disease or have a capacity to pass it to the next generation.
Genetic screening is helping in extracting out that small group of people from the larger population which might have a greater risk of developing a disease or carry a potential of having offspring that may have that disease as well. On the contrary, the term genetic testing merely focuses on an individual.
