Genetic testing is the process of examining DNA where the DNA is examine for chromosome, genes and proteins changes. Mainly used to detect genetically inherited disease, if the individual is a carrier of a genetically inherited disease or any possible presence of genetically inherited disease, but this method can also be used to determine a child's biological parents, a person's ancestry (usually to make a family tree), finding genetic diseases in the fetus, screening embryos for diseases, and figuring out the types or dosage of a medicine that is best for a certain person. However, genetic testing is not fully accurate, a positive result does not necessarily mean that someday he/she will develop the disease and vice versa (Clinic, 2013). In the past, genetic testing is used to search for abnormal chromosome …show more content…
Today, tests involve the analyzing of multiple genes to determine the risk or possibilities of developing certain and more common diseases (heart disease or cancer, for instance), and some non-medical related purposes.
There are many types of genetic testing, including: (1) Newborn screening – a testing used just after birth to identify genetic disorders that could be treated early in life. A blood sample is collected with a heel prick from the newborn 24–48 hours after birth and sent to the lab for analysis. An abnormal result doesn’t indicate that the child is diagnosed with the disorder. Diagnostic tests must follow the initial screening to confirm the disease. (2) Diagnostic
