What are the most common genetic tests?

Newer testing called cell-free DNA testing looks at a baby’s DNA via a blood test done on the mother. Newborn screening. This is the most common type of genetic testing. In the United States, all states require that newborns be tested for certain genetic and metabolic abnormalities that cause specific conditions.

What are 2 common types of genetic testing?

There are several types of genetic tests:

  • Molecular tests look for changes in one or more genes.
  • Chromosomal tests analyze whole chromosomes or long lengths of DNA to identify large-scale changes.
  • Gene expression tests look at which genes are turned on or off (expressed) in different types of cells.
