Genetic testing is a type of medical test that identifies changes in chromosomes, genes, or proteins. The results of a genetic test can confirm or rule out a suspected genetic condition or help determine a personâs chance of developing or passing on a genetic disorder.More than 1,000 genetic tests are currently in use, and more are being developed. Several methods can be used for genetic testing:Molecular genetic tests (or gene tests) study single genes or short lengths of DNA to identify variations or mutations that lead to a genetic disorder.he results of a genetic test can confirm or rule out a suspected genetic condition or help determine a personâs chance of developing or passing on a genetic disorder.

What is Biomedical Research. Biomedical research is the broad area of science that looks for ways to prevent and treat diseases that cause illness and death in people and in animals.This general field of research includes many areas of both the life and physical sciences.tilizing biotechnology techniques, biomedical researchers study biological processes and diseases with the ultimate goal of developing effective treatments and cures. Biomedical research is an evolutionary process requiring careful experimentation by many scientists, including biologists and chemists.
