Which term describes a blood test that determines the presence of a genetic disorder?

The term that describes a blood test used to determine the presence of a genetic disorder is genetic testing. This process involves analyzing a person's DNA to identify mutations or alterations that are associated with specific genetic conditions. Genetic testing can help diagnose inherited disorders, assess the risk of developing certain diseases, and inform treatment options. It includes various methodologies, such as looking for specific gene mutations or assessing chromosomal abnormalities.

Genome sequencing refers to a more comprehensive analysis of an entire genome rather than a specific test to identify genetic disorders. Biochemical analysis is typically used to measure levels of substances in the blood but does not specifically indicate the presence of genetic disorders; rather, it may help identify conditions related to metabolic processes. Metabolic screening often refers to a test used for newborns to identify certain metabolic disorders but is not specifically aimed at determining genetic conditions throughout an individual's life.
