How a DNA Test Works

How a DNA Test Works Published on: 22nd February 2023 Medically reviewed by: General Practitioner at First Response Healthcare Genetic testing involves examining your DNA. Genetic testing is a medical procedure that uses DNA to identify changes. These tests can help confirm or rule out suspected genetic conditions, as well as provide information about a person’s chance of developing or passing on a genetic disorder.

To understand how DNA test is performed, you need to know that genetic testing involves looking for changes in the following: Genes: Gene tests analyze variations (mutations) in a person’s genes in an effort to identify those that may increase the risk of developing a genetic disorder. There are two types of gene tests: narrow scope, which examines one or more genes, and large-scope testing, which looks at all of a person’s DNA. Chromosomes: Chromosomal genetic tests look for large-scale changes in a person’s DNA, such as an extra copy of a chromosome. Chromosomal genetic tests help one know about abnormalities that may lead to conditions like Down Syndrome or cancer. Proteins: Biochemical genetic tests involve measuring the level or activity of proteins or enzymes. Abnormalities in either of these can signal changes to a person’s DNA, which may lead to a genetic disorder.
